Error and Maintenance
The motor rotates without
a command.
There are inputs of small
values in speed control
mode.
Check if there is any inputs in
speed control mode.
Set the speed command
to 0.
Alternatively, change the
mode to position control.
There are inputs of small
values in torque control
mode.
Check if there is any inputs in
torque control mode.
Change the mode from
torque control to position
control.
The Servo Drive breaks
down.
Replace the Servo Drive
with a new one.
The motor rotates in the
reverse direction from the
command.
The value set on the
Rotation Direction Switching
(Pn000) is incorrect.
Check the value set on the
Pn000.
Chang the setting on the
Pn000.
The command given by the
host controller is incorrect.
• The absolute command is
set improperly in size.
• The incremental command
is set improperly in polarity.
• Check the present and
target values.
• Check the rotation
direction.
The holding brake does
not work.
Power is supplied to the
holding brake.
Check whether power is
supplied to the holding brake.
• Check the brake
interlock output (BKIR)
signal and the relay
circuit.
• Check that the holding
brake is not worn
down.
Motor rotation is unstable. The motor power cable or
encoder cable is wired
incorrectly.
Check the wiring of the motor
power cable's phases U, V,
and W and check the encoder
cable's wiring.
Wire correctly.
Low rigidity. It causes
vibration.
Measure the vibration
frequency of the load.
Enable the damping
control. Set the damping
filter frequency.
The load's moment of inertia
exceeds the Servo Drive's
allowable value.
Calculate the load inertia.
• Check if the manual
tuning can make a
proper adjustment.
• Increase the
Servomotor capacity.
Loose joint and/or large
clearance with the machine
Check the joint with the
machine.
Remove the joint
looseness with the
machine.
The pulse signal line's
connections are loose.
Check the pulse signal line's
wiring at the controller and
Servo Drive.
Wire correctly.
Check the controller's
command pulse type and the
Servo Drive's commands
pulse type.
Set the Servo Drive's
pulse type to match the
controller's command
pulse type.
The load and gain do not
conform.
Check the response
waveforms for speed and
torque.
Adjust the speed loop
gain to stabilize the
rotation.
