Why does Sunfar Inverter show over current during acceleration?
- MMiranda RobinsonAug 21, 2025
The Sunfar Inverter might show an over current during acceleration due to: * Short acceleration time: Adjust the acceleration time. * Improper V/F curve or torque boosting settings: Adjust the V/F curve or torque boosting parameters. * Restart after transient stop: If the rotating motor restarts after being re-energized upon a transient stop, set [F0.4.38] as 1 to recover operation in deceleration mode and restart after power off. * Inverter capacity: The frequency inverter may have smaller capacity, so select a frequency inverter with matched capacity level. * Encoder issues: If accelerating with PG, the encoder might be faulty or disconnected, so inspect the encoder and its connection.
