CHAPTER5 OPERATING

Profidrive Status Word (ZSW):

The status word indicates the status of the inverter (Inverter -> PLC).

			Status word
Bit	Value	Meaning	Remark
0	1	Ready to switch-on	Control word bit 0=0 and bits 1, 2, 10 are set to 1 (Ready to switch-on
			state).
	0	Not ready to switch-on	Control word bit 0, 1 or 2 (OFF1, OFF2, OFF3) is set to 0, or the inverter
			is tripped.
1	1	Ready for operation	Control word bit 0, 1 and 2 are set to 1. Inverter is not faulted (Ready
			state).
	0	Not ready for operation	Control word bit 0, 1 or 2 (OFF1, OFF2, OFF3) is set to 0, or the inverter
			is faulted.
2	1	Operation enabled	Control word bit 0, 1, 2 and 3 are set to 1. Inverter is not faulted (Enable
			operation state).
	0	Operation inhibited	Control word bit 0, 1, 2 or 3 (OFF1, OFF2, OFF3, Operation disabled) is
			set to 0, or the inverter is faulted.
3	1	Fault	Inverter is faulted.
	0	No fault	Inverter is not faulted.
4	1	ON2	Control word bit1=1.
	0	OFF2	OFF2 command active. Control word bit1=0 (OFF2 active state).
5	1	ON3	Control word bit2=1.
	0	OFF 3	OFF3 command active. Control word bit2=0 (OFF3 active state).
6	1	Start enable	Control word bit1 or 2 (OFF2, OFF3) is set to 0 or fault has been
			acknowledged (Switch-on inhibit state).
	0	No switch-on inhibit	Control word bit 0=0 and bit10=1 (Not ready to switch-onstate).
7		Not used
8	1	Frequency equal set-point	Actual output frequency does equal frequency set-point.
	0	Frequency not equal set-	Actual output frequency does not equal frequency set-point
		point	(i.e. motor accelerating/decelerating).
9	1	Bus control	Run command or frequency setting is valid via Profibus.
	0	Local control	Run command and frequency setting are invalid via Profibus.
10	1	Frequency within range	Actual output frequency is above or equal to the limit specified by “Arrival
			frequency at acceleration/deceleration 1” (C042/C043).
	0	Frequency out of range	Actual output frequency is below the limit specified by by “Arrival
			frequency at acceleration/deceleration 1” (C042/C043).
