Description

The invention relates to a method for setting parameters of electronic Motor controls for hoists, in particular cable and chain hoists.

• Einstellung der Hubwerksrichtung bei Rechtslauf des Motors durch Änderung der Polung,
• Einstellen des Verhaltens der elektronischen Bremse auf zwei- oder dreiphasiges Bremsen,
• Einstellen von ein oder zwei Hub-/Senkgeschwindigkeiten und ggf. deren Geschwindigkeit an sich,
• Verriegelung eines Steuerschalters,
• Wahl eines zeit- oder drehzahlgesteuerten Anlaufs,
• Überwachungsdrehzahl der Geschwindigkeiten,
• Zeitfilter der Drehzahl-Überwachung.

In the case of lifting gear with electronic motor control, the control parameters must be set for the application or customer. For example, in chain trains with electronic engine control, the following parameters are adjusted to adapt the engine to local conditions:

• Setting of the hoist direction with clockwise rotation of the motor by changing the polarity,
• Setting the behavior of the electronic brake to two- or three-phase braking,
• Setting one or two lifting / lowering speeds and possibly their speed itself,
• Locking a control switch,
• Choice of a time- or speed-controlled startup,
• Monitoring speed of the speeds,
• Time filter of the speed monitoring.

In addition, the setting of safety-critical parameters, such as the provision of a Error counter.

Typically, for these settings, a rewiring by jumpers, Switch fields, etc. made. However, this solution is not very variable and requires a high effort during commissioning or change the circumstances.

Also known is the setting via data interfaces by means of parameterization terminal or PC or laptop. However, this requires additional resources, the additional costs and effort cause.

EP 0 364 994 A1 and US 4,752,012 disclose electronic motor controls for Cranes in which the operating parameters are stored in a memory.

From Flender Loher: DYNAVERT® L Brief Instructions, as of 11.10.02 it is known to Parameter setting for drive converter to run the parameters sequentially and if necessary to change. A corresponding procedure is known from DE 39 107 18 A1 for Motor protection devices known.

The object of the invention is therefore to provide a method for setting parameters of to provide electronic engine controls on hoists, without additional Aid can be performed and a simple setting different Parameter allowed.

This object is achieved with the reproduced in claim 1 method.

(i) Starten des Modus zur Parametereinstellung,

(ii) Automatisches, sequentielles Durchlaufen und Anzeigen aller Parameter,

(iii) ggf. binäre Auswahl eines angezeigten Parameters,

(iv) ggf. Änderung der Einstellung des ausgewählten Parameters,

(v) Speichern der Änderungen,

(vi) Beenden des Modus zur Parametereinstellung,

durchlaufen. Diese Verfahrensweise wird dabei unter Verwendung der üblicherweise in Hebezeug-Steuereinrichtungen vorgesehenen Hubschalter, Senkschalter und Not-Aus-Schalter in Verbindung mit der Anzeige zu Diagnosezwecken durchgeführt. Es sind keine weiteren Hilfsmittel, wie zusätzliche Schalter, Anzeigen oder Schnittstellen notwendig. Ferner kann das Verfahren mit dem zur Steuerung vorhandenem Mikroprozessor durchgeführt werden. Eine zusätzliche teuere Logik ist nicht notwendig.
Unter "binärer Auswahl" wird die Auswahl zwischen zwei vorgegebenen Möglichkeiten verstanden. Hier handelt es sich konkret um die Auswahl eines Parameters oder Unterparameters durch Betätigung einer Taste. Insbesondere ist dies der Hubschalter. Die zweite Möglichkeit, hier Abwahl ohne Änderung, wird durch Betätigung einer zweiten Taste, insbesondere des Senkschalters ausgewählt. In the method according to the invention, the steps for parameter setting of electronic engine controls in hoists

(i) starting the parameter setting mode,

(ii) automatically, sequentially traversing and displaying all parameters,

(iii) optionally binary selection of a displayed parameter,

(iv) if necessary, changing the setting of the selected parameter,

(v) saving the changes,

(vi) terminate the parameter setting mode,

run through. This procedure is carried out using the commonly provided in hoist control devices Hubschalter, lowering switch and emergency stop switch in conjunction with the display for diagnostic purposes. There are no further aids, such as additional switches, displays or interfaces necessary. Furthermore, the method may be performed with the microprocessor for control. An additional expensive logic is not necessary.
By "binary selection" is meant the choice between two given possibilities. Specifically, this is the selection of a parameter or sub-parameter by pressing a key. In particular, this is the stroke switch. The second possibility, here deselection without change, is selected by pressing a second button, in particular the lowering switch.

The stroke switch thus has the meaning of the positive selection or activation and the lowering switch corresponding to the deselection or negative acknowledgment.

By the binary selection of a displayed parameter or subsequently displayed Subparameters, it is thus possible with the inventive method that already to use existing control devices and still a simple and comprehensive Allow setting.

The usual switches for raising and lowering are usually performed in two stages, d. H. in the first position they allow the selection of a first speed "V1" and in the second position, the selection of a second speed "V2". The two-stage is usually determined by the pressure or the Eindrücktiefe the usual button. To make sure that really is an operation in parameter setting mode can therefore be provided that the switch or Pushbuttons are considered to be actuated only when actuated to the extent that the second stage is triggered.

To leave the parameter setting mode at any time and in the to change normal operating mode, the invention provides that by Operation of the emergency stop switch, the parameter setting mode at any time under Storage of the changes made until then left or ended can.

To select or deselect the displayed parameter or subparameter allow the parameters to be displayed one after the other for about 4 seconds, during which a selection is possible by operating the Hubschalters. The same applies to the sub-parameters.

(a) Betätigen und Halten des Not-Aus-Schalters,

(b) Betätigen und Halten des Hubschalters und

(c) Lösen des Not-Aus-Schalters.

To start the parameter setting mode in step (i), it may be provided that the following steps must be performed sequentially:

(a) actuating and holding the emergency stop switch,

(b) Actuating and holding the lift switch and

(c) releasing the emergency stop switch.

(d) Anzeige des Modus zur Parametereinstellung,

(e) Bestätigung der Wahl des Modus zur Parametereinstellung, insbesondere durch Lösen des Hubschalters und

(f) ggf. Anzeige des Starts des Modus zur Parametereinstellung.

In addition, to start the parameter setting mode in step (i) after step (c), the following steps may be performed:

(d) displaying the parameter setting mode,

(e) confirming the choice of the parameter setting mode, in particular by releasing the stroke switch and

(f) if applicable, display of the start of the parameter setting mode.

To make sure that the parameter setting mode is actually started In addition, it may be additionally provided that the actuation (e) during the display (d) which only takes place over a predetermined period of time (eg about 2 seconds). takes place, must take place. The parameter setting mode can be displayed by Display of "P" done. Accordingly, the actual start of the mode (f) by Display of "o" for O.K. respectively.

(a) Betätigung des Hubschalters zur Auswahl eines angezeigten Parameters oder

(b) Betätigung des Senkschalters zur Abwahl des angezeigten Parameters.

Advantageously, the following steps are performed in step (iii):

(a) operate the lift switch to select a displayed parameter or

(b) Press the down switch to deselect the displayed parameter.

When the lowering switch is pressed to deselect the displayed parameter (b) then the next parameter is displayed.

(a) Betätigung des Hubschalters zur Änderung eines ausgewählten Parameters oder

(b) Betätigung des Senkschalters zur Abwahl des ausgewählten Parameters ohne Änderung.

In a variant, the following steps are performed in step (iv):

(a) operate the lift switch to change a selected parameter or

(b) Press the down switch to deselect the selected parameter without change.

(c) automatische sequentielle Anzeige aller Unterparameter und

(d) ggf. binäre Auswahl eines angezeigten Unterparameters zur Änderung der Einstellung des ausgewählten Parameters durch Betätigung des Hubschalters oder

(e) Betätigung des Senkschalters zur Abwahl eines ausgewählten Parameters ohne Änderung.

In the case of subparameters, in step (iv), in addition to step (a), the following steps are performed:

(c) automatic sequential display of all sub-parameters and

(D) if necessary, binary selection of a displayed subparameters for changing the setting of the selected parameter by pressing the stroke switch or

(e) operate the down switch to deselect a selected parameter without change.

The display and selection of the specified sub-parameters is thus analogous to the Display and selection of parameters. To the operator the specification of subparameters can be announced in step (iv) (c) first for z. B. about 2 seconds "o" for "open" are displayed before the actual subparameter pass through sequentially become.

Conveniently, after changing or deselecting the displayed parameter or Subparameters in step (iv) continue with the next parameter in step (ii). Thus, a simple and quick setting of all parameters with the invention Guaranteed method using a conventional control device.

As a display, the single-digit 7-segment display can be used for diagnostic purposes, which is usually available and therefore does not need to be additionally provided. The Display can be arranged as desired, as long as it is visible to the operator. Of course, any, z. b. multi-digit display used for example, to display more than 10 parameters.

In order to keep the ad as simple as possible, it is advantageous if the available parameters by single digits, d. H. "0" to "9" are displayed and possibly available sub-parameters by a single letter, d. H. "A", "b", "C", "d", "E", "F" etc. are displayed. The selection of the symbols is preferably carried out in such a way that a good recognizability on the single-digit 7-segment display is possible and Confusions are thus excluded.

To prevent momentous incorrect settings in safety-critical Functions can be provided that the setting of the corresponding parameter only after activation of two parameters. So it has to be the first Parameter 8 is activated and then parameter 9 is activated by positive selection be activated by the Hubschalter before the error counter cleared or is reset.

As parameters to be set, all possible parameters come into consideration. Especially these are the following parameters: reverse polarity, 2 or 3-phase electronic braking, one or two lifting / lowering speeds and their speed in itself, locking a control switch, time or speed controlled Start-up, monitoring speed of the speed, time filter of the speed monitoring and error counter reset.

Further features, details and advantages of the invention will become apparent from the following description of the drawing. It shows:

Fig. 1

schematically a conventional control device for carrying out the method according to the invention.

FIG. 1 shows schematically one for carrying out the method according to the invention suitable, as a whole with 10 designated conventional hoist control. This sits down from the actual controller 1 and thus a cable connection. 3 connected control panel or control switch 2 together.

The controller 1 comprises a microcontroller 7 for controlling and monitoring the Functions, especially of the engine. The microcontroller 7 is about a Motor switch 9 connected to this.

The controller 1 further comprises a display 8, which is provided for diagnostic purposes and is designed as a single-digit 7-segment indicator light. It serves during the Mode for setting parameters in the context of the method according to the invention also for displaying the status or user guidance. The display 8 is arranged such that it is visible during operation.

The hand-operated operating part 2 comprises three switches or buttons. The emergency stop switch 4 For immediate shutdown in case of danger, to start the parameter setting mode and also used for its immediate termination. By far are including the stroke switch or button 5 and the lowering switch or button 6, usually with different arrow symbols, such. B. up or to marked below. The button 5 causes when you lift the Load through the appropriate engine control. Accordingly, the button 6 causes Operation a lowering of the load by reverse motor control.

The buttons 5 and 6 are designed as two-stage buttons, d. H. they have two Pressure points assigned to different lifting / lowering speeds V1 and V2 can be. So can the slight lifting / lowering speed by light pressure V1 and the higher lifting / lowering speed V2 is selected by stronger pressure become.

Hereinafter, the exemplary implementation of a variant of the invention Explained method based on the operation of the control panel 2 in more detail.

First, the parameter setting mode must be started. This will be the first the emergency stop switch 4 is operated and held. Subsequently, the stroke switch 5 in his position V2 pressed and held. Thereafter, the emergency stop switch 4 is released and After about 10 seconds, the display will show 8 "P" for parameter setting mode. Before the display 8 goes out after about 2 seconds, the stroke switch 5 is complete solved. If the display has previously gone out, the stroke switch 5 must again be in its Position V2 are pressed and held. Finally, you have to wait until the ad 8 an "o" for O.K. represents, indicating that the parameter setting mode was started.

"Heben-V2" =

Ja bzw. Ein

"Senken-V2" =

Nein bzw. Aus

"Not-Aus" =

Parametereinstellungsmodus beenden unter Speicherung der bis dahin erfolgten Änderungen

The switches 4, 5 and 6 therefore have the following meanings in the parameter setting mode in addition to their actual meaning in normal operation:

"Lift-V2" =

Yes or one

"Sink V2" =

No or Off

"Emergency stop" =

End parameter setting mode by saving the changes made so far

If the parameter setting mode has been activated successfully, successively all available parameters are shown on the display 8. This is done by means of the digits "0" to "9", each of the digits representing a parameter.
