Resetting the travel direction counter
Information
At the end of the maximum change of direction, the ZAdyn4C is locked and the error
"E950 TD_CNT:
Drive limit"
appears on the display.
To enable the cabin to be moved to the position for replacement of the suspension means after locking
the frequency inverter, the ZAdyn4C must be switched off and back on. Further travel is then possible.
After successfully replacing the suspension means, the password has to be entered in the
Statistics
menu and the reverse counter set to a new initial value:

Restore the counter reading from the absolute value encoder
The counting value of the travel direction change counter is automatically saved in the absolute value
encoder. This is performed at the following intervals:
•
every 100 changes in direction up to 1,000 changes in direction
•
every 1,000 changes in direction up to 10,000 changes in direction
•
every 3,000 changes in direction from 10,000 changes in direction
The function is possible in absolute value encoders with EnDat, Codeface and Hiperface interface.
The current counter reading can be loaded into the ZAdyn from the absolute value encoder:
