Significance of the individual bits
Bit Value Significance Comments
0 0 Not on standby
1 Standby Initialisation complete, load relay on, output voltage blocked
1 0 Not operational Causes: No On command, an error has occurred, OFF 2 or OFF 3
active, switch-on block status active.
1 Ready for operation On command active, no errors. The inverter can be started with the
ENABLE OPERATION command.
2 0 Operation blocked
1 Operation enabled Output voltage enabled, run-up to present setpoint.
3 0 No errors
1 Error Drive malfunctioning therefore out of order, if acknowledgement is
successful, will go to switch-on block status.
4 0 OFF 2 OFF 2 command active
1 No OFF 2
5 0 OFF 3 OFF 3 command active
1 No OFF 3
6 0 No switch-on block
1 Switch-on block Goes through OUT 1 to Standby status
7 0 No warning
1 Warning Drive still in operation, no acknowledgement necessary
8 0 Actual value not O.K. Actual value does not match the setpoint (with posicon: Setpoint
position not reached)
1 Actual value O.K. Actual value matches the setpoint (setpoint reached)
(with posicon: Setpoint position reached)
9 0 Local guidance Local guidance active on device
1 Guidance required The Master is called upon to take over the guidance.
10 0 MFR 1 reference value
undershot Programmed function of the MFR 1 not met or
actual value < programmed reference value
1 MFR 1 reference value
reached Programmed function of the MFR 1 met or
actual value > programmed reference value
