System
Z-phase is not detected.
Check that the Z-phase matches to the center of proximity dog.
Execute the homing matching to the controller correctly.
+RPLQJFUHHSVSHHGLVIDVW
Lower the homing speed at origin proximity. Or widen the origin
sensor.
Wiring
Chattering of proximity sensor
(proximity dog sensor) output .
Check the dog sensor input signal of the controller with
oscilloscope.
Review the wiring near to proximity dog and make a noise measure
or reduce noise.
Noise is on the encoder line.

treatment of I/F cables, use of a twisted pair or separation of power
and signal lines.
No Z-phase signal output.
Check the Z-phase signal with oscilloscope. Check that the Pin-

controller. Connect the earth of the controller because the open
collector interface is not insulated. Replace the motor and driver.
Request for repair.
Miswiring of Z-phase output.
Check the wiring to see only one side of the line driver is connected
or not. Use a CZ output (open collector if the controller is not
differential input.

Motor bearing
Check the noise and vibration near the bearing of the motor while
running the motor with no load. Replace the motor to check.
Request for repair.
Electro-magnetic sound, gear
noise, rubbing noise at brake
engagement, hub noise or
rubbing noise of encoder.
Check the noise of the motor while running the motor with no load.
Replace the motor to check. Request for repair.
