Cause : Excessive positioning deviation comes when the actual position of the controlled system (like a motor) deviates significantly from the desired position.
"d0" fault in Fuji FRENIC-VG drive indicate "excessive positioning deviation error". This means the position error exceeds the allowable limit set in the drive's parameters. This is usually related to applications involving servo control or positioning tasks, where the drive is controlling the precise position of a motor.
Troubleshooting Steps:
-
Check Positioning Parameters: Review and adjust the drive's positioning parameters, including gain settings, acceleration/deceleration times, and allowable deviation limits. Ensure they are appropriate for your application.
-
Inspect Mechanical Components: Examine the mechanical setup for issues like loose couplings, gear backlash, or any physical obstructions that could cause the motor to deviate from its commanded position.
-
Check Load and Disturbances: Ensure that the load is within the drive's capacity and that there are no sudden disturbances that could affect the motor's ability to maintain its position.
-
Verify Feedback Device Operation: Check the encoder or other feedback devices for proper operation. Ensure they are correctly aligned and that their signals are being correctly received by the drive.
-
Inspect Wiring and Connections: Verify that all connections between the drive, motor, and feedback devices are secure and free from damage or interference.
