Status word 1 (ZSW1)
Status word 1 (bits 0 to 10 as per PROFIdrive Profile and VIK/NAMUR, bits 11 to 15 specific
to SINAMICS G120).
Table 5-33 Bit assignments status word 1 (for all PROFIdrive and VIK/NAMUR telegrams)
Bit Value Meaning Remarks
1 Ready to switch on Power supply is switched on, electronics initialized, pulses
disabled.
0
0 Not ready to switch on --
1 Ready to operate Inverter is switched on (ON command is applied), no fault is
active, inverter can start when "Enable operation" command
is issued. See control word 1, bit 0.
1
0 Not ready to operate --
1 Operation enabled Drive follows setpoint. See control word 1, bit 3. 2
0 Operation disabled --
1 Fault present Drive has faulted. Drive is faulty and thus inoperative,
switches to starting lockout state after successful correction
and acknowledgement of fault.
3
0 No fault --
4 1 Coast Stop not activated --
