Cause
Remedy
A
The product of the square of rotational
motor speed and the combined inertia of the
motor and load (rotation energy) exceeds
the capacity of the dynamic brake resistor
built into Servo Driver.
• Lower the rotational speed.
• Lower the load inertia.
• Do not frequently use dynamic braking.
B
Circuit board (1PWB) is defective.
Replace the Servo Driver.
