9.10.2 Calibration
9.10.2.1 General
To enable operation of the synchronous machine it is necessary to measure the angle offset between
the encoder zero point and the electrical zero point of the motor winding (
calibration
). The converter
features different variants for performing this measurement, with the calibration method with the
synchronous machine turning being the preferred variant. This measurement is slightly more precise
and assignment of the direction of rotation is done automatically.
9.10.2.2 Calibration with synchronous machine turning
During the calibration, the inverter automatically detects whether the ropes are putted on or not and
activates the appropriate method:
9.10.2.2.1 Requirements for the measurement without ropes
•
The measurement must be carried out with a free-running motor and without a load (slack
rope).
•
Even small friction torques can falsify the measuring result so that no proper operation is
possible
9.10.2.2.2 Requirements for the measurement with ropes putted on
•
Cabin and counterweight must be free to move
•
The rated load of the motor must not be exceeded (nominal torque)
•
For the driving distance, approx. 3x the traction wheel circumference is to be assumed
•
Both directions are possible
•
In the first calibration drive, the direction of movement is unknown
•
No persons may be in or on the cabin or in the shaft
•
The load transfer is unregulated: a rollback of several centimeters is normal. Vibrations and
noises are normal.
9.10.2.3 Procedure
Activation of calibration:
Measurement in menu extended-synchronous machine-calibration=1.
Definition of drive commands by means of restoring control
Motor turns until the measurement is complete, the status of the
measurement is displayed.
Now, cancel all drive commands.
The measured angle offset is displayed
Save the result by pressing the "E" key. Press the "C" key to quit.
