General tips for the adaptation of the VVVF controller to the motor:
Some drive manufacturers (e.g. Schindler) always "stamp" their drives with the synchronous speed
(no slip). This must not be mixed up with the nominal speed the drive achieves when loaded. The
slip, i.e. the difference between the synchronous speed and the nominal speed is
approx. 2.5 to 4 %
in the case of one-speed motors for VVVF controllers . In the case of 50 Hz motors with 2 pole
pairs, this corresponds to a nominal speed of approx. 1440 – 1465 rpm . In the case of pole-changing
motors , the slip is approx. 5 to 8 % , which corresponds to a nominal speed of 1380 to 1425 rpm .
In order to ensure a perfect driving behaviour, the rated speed must be adjusted at the VVVF
controller. This speed must not be mixed up with the actual speed (V4). This is always less
than 1500 rpm in the case of 50 Hz motors !
8.4 First travel operation
Issue travel command from the control system. The following commands are required for a travel
operation at speed V1:
Travel up: GS, RO and V1
Travel down: GS, RU and V1
In the case of an upward movement of the cabin, a positive speed must
be displayed.
In the case of a downward movement, the value is negative.
Tip for checking the incremental encoder (only with Vector Asynchronous operating mode):
After entering system-related data, we recommend checking the general function of the incremental
encoder before running for the first time. This can be done easily:
Call up the standard display on the unit's display. If you are in a sub-
menu, press the
"C" key as often as necessary until the following text is
displayed.
Release brake briefly so that the cabin drifts upwards a few centimetres
and observe the display at the same time. A
positive speed must be
displayed. If the speed is negative, the sensor tracks on the unit have to
be reversed (terminal 27, 28 and 62, 63). If no speed is displayed, check
the encoder connection and the entered data (number of encoder pulses
and supply voltage) in the menu
General Settings.
If the assignment between the sense of rotation of the motor (terminals U, V, W) and incremental
encoder tracks is defective or if defective or no incremental pulses are detected, the motor runs for
some 2 seconds before it is switched off and the error message "Wrong tacho polarity" and "no start-
up" is displayed (see troubleshooting
Section 15.1
).
