Explanation of the Status Bits
B
it 00, Control not ready/ready
When bit 00 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3) - or the frequency
converter is switched off (trip).
When bit 00 = "1", the frequency converter control is ready, but there is not necessarily power supply to the
unit present (in the event of external 24 V supply of the control system).
Bit 01, VLT not ready/ready
Same significance as bit 00, however, there is a supply of the power unit. The frequency converter is
ready when it receives the necessary start signals.
Bit 02, Coasting/Enable
When bit 02 = "0", bit 00, 01 or 02 of the Control word is "0" (OFF 1, OFF 2 or OFF 3 or coasting) - or the
frequency converter is switched off (trip).
When bit 02 = "1", bit 00, 01 or 02 of the Control word is "1"; the frequency converter has not tripped.
B
it 03, No error/Trip
When bit 03 = "0", no error condition of the frequency converter exists.
When bit 03 = "1", the frequency converter has tripped and requires a reset signal before it can start.
Bit 04, ON 2/OFF 2
When bit 01 of the Control word is "0", then bit 04 = "0".
When bit 01 of the Control word is "1", then bit 04 = "1".
Bit 05, ON 3/OFF 3
When bit 02 of the Control word is "0", then bit 05 = "0".
When bit 02 of the Control word is "1", then bit 05 = "1".
