ZSW1 - status word (StatW)

Status word 1 (ZSW1) is identical to the specification in the PROFIBUS profile "Variable-
speed drives".
Bits 0 to 10 correspond exactly to the specifications for the PROFIBUS profile "Variable-
speed drives". The use and non-use of specific bits is marked accordingly.
The table below describes the assignments of the bits in status word 1.

Value Note
1 Power supply switched on and system initialized
0 Not ready for switch on
1 Ready to run, system is switched on ("ON" command present), no fault active, system
can start as soon as the "Enable operation" command is given (see also STW1 bit 0)
0 Not ready to run, no "ON" command
1 Operation enabled, drive order is executed (system follows the setpoints)
See also STW1 bit 3
0 Drive order is not executed, operation is locked
1 Drive is faulty and therefore out of service.
The drive switches to "switching on inhibited" once the fault has been acknowledged
and the cause has been remedied
0 No fault present
1 No OFF2 active
0 Coast down (deenergize) active, an OFF2 command is present
1 No OFF3 active
0 Rapid stop (stop) active, an OFF3 command is present
