A (Rated Speed): Sets the nominal speed for the connected motor.
C (Rated Current): Adjusts the motor current limit (1A to 5A).
F (Acceleration Time): Defines the time taken to reach the target speed.
H (Hall Sensor): Must be set to "ON" for motors using Hall sensors to avoid "Error 01".
L (Loop Control): Toggles between open-loop and closed-loop (feedback) operation for higher precision.
U (Pole Count): Must be set accurately (Total permanent magnets divided by 3) to ensure correct speed readings. Operation and Maintenance Tips
