Reason for alarm 1: Wrong selection of regenerative resistor or external regenerative resistor not connected.
Check: Confirm the connection status of the regenerative resistor.
Remedy: Recalculate the regenerative resistance value and set the parameter values of P1-52 and P1-53 correctly again. If the alarm is still not cleared, please return the driver to the original factory.
Reason 2: When the regenerative resistor is not used, the parameter of the regenerative resistor capacity (P1-53) is not set to zero.
Check: confirm whether the regenerative resistance capacity parameter (P1-53) is zero;
Treatment method: If the regenerative resistor is not used, please set the regenerative resistor capacity parameter (P1-53) to zero.
Alarm reason 3: Parameter setting error
Check: Confirm the setting value of the regenerative resistance parameter (P1-52) and the setting of the regenerative resistance capacity parameter (P1-53).
Treatment method: reset the parameter values of P1-52 and P1-53 correctly
If the above method still fails to lift the alarm, please return to the original factory for repair.
