5.12.4 Overtravel Warnings

You can set the system to detect an A.9A0 warning (Overtravel) if overtravel occurs while the
servo is ON. This allows the SERVOPACK to notify the host controller with a warning even
when the overtravel signal is input only momentarily. An alarm occurs only if overtravel occurs
while the servo is ON. An overtravel warning will not be detected when the servo is OFF, even if
overtravel occurs.
Important
The following parameter is set for this function.

1. The occurrence of an A.9A0 warning will not stop the motor or have any affect on host control-
ler 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 programming 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 controller.
2. When overtravel occurs, the SERVOPACK will perform stop processing for overtravel. There-
fore, when an A.9A0 warning occurs, the Servomotor may not reach the target position speci-
fied by the host controller. Check the feedback position to make sure that the axis is stopped
at a safe position.
