Category: Warning

Cause

1. Incorrect or poor motor wiring or encoder wiring
2. The load is too heavy, and motor output effective torque exceeds rated torque during prolonged continuous operation
3. Acceleration/deceleration too frequent or excessive load inertia
4. Inappropriate gain adjustment or excessive rigidity
5. Incorrect drive or motor model setting
6. Mechanical factors cause motor stalling and excessive operating load
7. Servo drive fault

Corrective action

1. Compare with the correct wiring diagram and check wiring between the motor, drive, and encoder. ◆Connect cables according to the correct wiring diagram. ◆Prefer our standard cables. ◆For self-made cables, make and connect them according to the hardware wiring instructions.
2. Confirm the motor or drive overload characteristics. Check whether drive average load ratio (2008-0Dh) exceeds 100.0% for a prolonged period. Replace with a higher-capacity drive and matching motor, or reduce the load and increase acceleration/deceleration times.
3. Check the mechanical inertia ratio or perform inertia identification, and check inertia ratio 2008-10h. Confirm the single cycle during cyclic servo motor operation. Increase acceleration/deceleration times.
4. Observe whether the motor vibrates or makes abnormal noise during operation. Readjust the gain.
5. Check bus motor model 2000-06h and drive model 2001-0Bh. Check the drive nameplate, set the correct drive model (2001-0Bh), and update the motor model to a matching model.
6. Use the Inovance drive commissioning platform or panel to check the operating command and motor speed (200B-01h): ◆Operating command in position mode: 200B-0Eh (input position command counter) ◆Operating command in speed mode: 200B-02h (speed command) ◆Operating command in torque mode: 200B-03h (internal torque command). Confirm whether the operating command is not 0 or is very large while motor speed is 0 in the corresponding mode. Eliminate mechanical causes.
7. Turn off the power, then power on again. If the fault remains after powering on again, replace the servo drive.
