If operation mode “Control via remote contacts” is used, controller release must be
turned on at STOA (Terminal X210A.3) and STOB (Terminal X210B.2) and
control word must be set in order to be able to start the drive.
Operation modes “Control via contracts” and “Control via remote contacts” only su

ACTIVE CUBE frequency inverters support an external 24 V power supply for the fre-
quency inverter control electronics. Even when mains voltage is disconnected, co
munication between the controller (PLC) and the frequency inverter is still possible.
Bit 4 “Power supply –
enabled” of the status word shows the current mains power
supply status:
Bit 4 “Power supply – enabled” = 0
signals “No mains voltage”, starting of drive not
possible.
Bit 4 “Power supply – enabled” = 1 signals “Mains voltage on”, drive ready for star
