Bit Meaning
0 ON/OFF1
1 OFF2
Note:
Control signal OFF2 is generated by ANDing BI: p0844 and BI: p0845.
2 Reserved
3 Enable operation
4 Reserved
5 Inhibit motor operation
Note:
When "Inhibit motoring operation" is present, power can still be drawn from the DC link. The DC link voltage is then
no longer controlled. The voltage level is the same as the rectified value of the current line voltage.
6 Inhibit regenerating
Note:
If regenerative operation is inhibited and power is fed to the DC link (e.g. by braking the motor), the DC link voltage
increases (F30002).
7 Acknowledge error
Note:
Faults are acknowledged at a 0/1 edge via BI: p2103 or BI: p2104 or BI: p2105.

1 Control via PLC
This signal must be set so that the process data
transferred via PROFIdrive is accepted and
becomes effective.
0 No control via PLC
Process data transferred via PROFIdrive is
rejected - i.e. it is assumed to be zero.
