Meaning Remarks
0 0 Not ready to start
1 Ready to start Initialisation completed, charging relay ON, output voltage disabled
1 0 Not ready for operation Causes: No command has been activated, fault is signaled, OFF2 or OFF3
activated, starting disabled state activated
1 Ready for operation ON command activated, no faults present. The inverter can be started with the
command ENABLE OPERATION
2 0 Operation not enabled
1 Operation enabled The output voltage is enabled; ramp to the existing setpoint
3 0 No error
1 Fault Drive fault resulting in stoppage; this state is changed to starting disabled after
the fault has been successfully acknowledged
4 0 Voltage not enabled OFF2 command applied
1 Voltage enabled
5 0 Emergency stop OFF3 command applied
1 No emergency stop
6 0 Starting not disabled
1 Starting disabled Switches first to OFF1, then to ready-to-start status
7 0 No warning
1 Warning active Drive operation continues, no acknowledgement necessary
8 0 Setpoint not reached Actual value does not match the setpoint (with posicon: failure to reach setpoint
position)
1 Setpoint reached Actual value matches required setpoint (setpoint has been reached)
(with posicon: setpoint has been reached)
9 0 Bus control not active Guidance on local device has been activated
1 Bus controller active The master has been requested to assume guidance.

Table 4: Status word (ZSW)
4.1.3 Frequency inverter status machine
The frequency inverter passes through a status machine. The changes between various states are
triggered by the respective control commands in the process data control word. The actual status is
returned in the process data status word.
After switching on, the inverter is in switch-on disabled status. This status can only be ended by
transmitting the “Shut down (Off 1)” command.
The answer to a master telegram normally does not yet contain a reaction to the control command.
The controller must check the answers from the slaves as to whether the control command has been
carried out.
The following bits indicate the status of the frequency inverter:
