Explanation of the Status Bits
Bit 00, Control not ready/ready:
Bit 00 = ’0’: The frequency converter trips. Bit 00 = ’1’: The frequency converter controls are ready but the power component does not necessarily receive
any power supply (in case of external 24 V supply to controls).
Bit 01, Drive ready:
Bit 01 = ’1’: The frequency converter is ready for operation but the coasting command is active via the digital inputs or via serial communication.
Bit 02, Coasting stop:
Bit 02 = ’0’: The frequency converter releases the motor. Bit 02 = ’1’: The frequency converter starts the motor with a start command.
Bit 03, No error/trip:
Bit 03 = ’0’ : The frequency converter is not in fault mode. Bit 03 = ’1’: The frequency converter trips. To re-establish operation, enter [Reset].
