- if, while at a standstill, the drive is rotated externally by more than the
value in the positioning window
This bit is reset:
- by transmitting a new positioning command
- after a start-up reference loop has been correctly executed
Bit 12
:
Incorrect target value
This bit is set:
- if a transferred target value lies outside the range of the limit switches,
caused e.g. by the current referencing value (ISDU 119)
- if a transferred target value lies within the range of the limit switches,
but would leave the specified range during the required loop
This bit is reset:
- by transmitting a valid target value
Bit 13
:
Motor power was missing
This bit is set:
- if the motor voltage is less than the UMot limit (ISDU 179) or above 30V
when initiating a positioning run or start-up reference loop
- if the motor voltage leaves the specified range during the run
This bit is reset:
- if the motor voltage is greater than the UMot limit and under 30V when
initiating a positioning run or start-up reference loop
Bit 14/15
: Forward/reverse limit reached
This bit is set:
- if the limit value is reached during a manual run (not when reached
during a positioning run)
- if a limit is modified such that the current position lies beyond it.
- if, when at a standstill, the drive is moved to a position beyond the
range defined by the limit switches by an external force
This bit is reset:
- when the actual position is again within the positioning range limits
(exception: after completing a manual run, the drive is at the range
limit, still within the positioning window and new run command has not
yet been issued).
