– The occurrence of an A.9A0 warning will not stop the motor or have
any effect on host controller motion operations. The next step (e.g.,
the next motion or command) can be executed even if an overtravel
warning exists.
However, depending on the processing specifications and program-
ming for warnings in the host controller, operation may be affected
when an overtravel warning occurs (e.g., motion may stop or not
stop). Confirm the specifications and programming in the host con-
troller.
– When overtravel occurs, the SERVOPACK will perform stop pro-
cessing for overtravel. Therefore, when an A.9A0 warning occurs, the
Servomotor may not reach the target position specified by the host
controller. Check the feedback position to make sure that the axis is
stopped at a safe position.
The following parameter is set for this function.
