7.2 The reason and handling of alarm
Err 1 (Over speed)
Potential cause Check Handle
Servomotor U
、
V
、
W
connection is not correct
Check U
、
V
、
W wiring Correct U
、
V
、
W wiring. The U
、
V 、 W must connect with servo
driver terminal U 、 V 、 W
correspondently.
Speed overshoot Check the operation status
and the parameters Adjust servo gain to reduce the
overshoot; In speed control mode
can increase
acceleration/deceleration time.
Encoder wiring error Check the encoder wiring Correct wiring.
Err 2 (Main circuit over-voltage)
Potential cause Check Handle
The voltage of input AC
power supply is too high Check the voltage of
power supply Use correct power supply
according with the specifications.
Regeneration fault Regenerative resistor
and/or IGBT damaged;
Connection circuit is open.
Repair.
Regeneration energy too
large Check the regeneration
load factor Decrease the start-stop frequency.
Increase acceleration/deceleration
time
Reduce the torque limit.
Reduce the load inertia.
Replace a bigger power servo
driver and servomotor
Replace a bigger brake resistor
