Error name
Speed has exceeded the
Overspeed
instantaneous permissible speed.
Current that flew is higher than the
Overcurrent permissible current of the servo
amplifier.
Description
15 - 40
MELSEC-Q
Cause
Small acceleration/deceleration
time constant caused overshoot to
be large.
Servo system is instable to cause
overshoot.
The setting value of the electric gear
ratio is large.
Fault in the encoder.
Output phases U, V, W phase of the
servo amplifier were connected with
each other.
Transistor of the servo amplifier
damaged.
Ground fault occurred in servomotor
power (U, V, W).
External noise caused the
overcurrent detection circuit to
misoperate.
