Overspeed
•
The rotation speed has exceeded the
instantaneous permissible speed.
•
When the acceleration/deceleration overshoots,
check the acceleration/deceleration time constant
in the fixed parameters.
•
If the servo gain cannot be set to a proper value:
-
Reduce the load inertia moment ratio (servo
parameter) of the servo motor.
→
Refer to Subsection 11.2.2
-
Review the acceleration/deceleration time
constant.
•
Change the servo motor.
