Troubleshooting

Table 7.1: Troubleshooting

Symptom

Cause

Action

Motor cannot be rotated
manually without
connecting the
controller.

Mechanical interference

Remove interference.

Motor three-phase short circuit

Fix three-phase short circuit.

Motor can’t rotate at
all.

Wrong cable wiring

Check the cable connected to the controller.

Current overload

Check whether there are interfering objects and remove
them.
Fix the brake clamping failure.

Over temperature protection

Check the over temperature setting of controller.

Abnormal insulation resistance

Measure insulation resistance after cooling
Measurement of stator three-phase to ground (U/V/W to PE):
1000

60 sec > 100

at 25

℃

If it does not reach 100

, please contact HIWIN.

Wrong rotating
direction

Wrong encoder setting

Check encoder setting.

Wrong motor power cable wiring Interchange the two-phase power cable connected to the

controller.

Smell of burning

Abnormal operation of cooling
system

Check cooling system.

Wrong controller setting

Check controller setting.

Wrong motor parameters setting Check motor parameters setting.

Abnormal temperature
of motor outer casing

Speed is too slow

Use the stall condition when switching frequency < 1 Hz.

Abnormal operation of cooling
system

Check cooling system.

Wrong controller setting

Check controller setting.

Wrong motor parameters setting Check motor parameters setting.

Abnormal operation of bearing

Check installation.

Unstable rotation
(vibration)

Insulation failure

Check the resistance value of phase/earth is larger than
50

Wrong encoder installation

Check installation stiffness of encoder.

Wrong encoder signal

Check encoder grounding and connection.

Wrong controller setting

Check controller setting.

Wrong motor parameters setting Check motor parameters setting.

Hard to rotate or
abnormal friction noise

Abnormal installation of rotor

Check installation.

Unbalanced system

Check the dynamic balance

Loose system

Fix it tight again

Foreign object exists in air gap.

Remove foreign object.

Motor generate local
high heat (uneven)

Air bubbles blocked in the cooling
circuit

Remove air bubbles or increase flow rate to remove air
bubbles.

Incorrect position of inlet and
outlet of cooling circuit

Check the inlet/outlet of cooling circuit to fit according to
approved drawing.
