Cause:
- no signal is present at the digital input parameterized with the function "ZR_RDY" at the start of the trip
Remedial action:
- exit the parameter change level of the ZArec
- check whether there is an active error at the ZArec
- check the parameter "BC_TYP = ZArec" in menu "Encoder & BC"
- check the wiring between ZAdyn and ZArec
