Bit Meaning
4 Reserved
5 Inhibit motor operation
Note:
During "Inhibit motoring operation", 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 regenerative operation
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 fault
Note:
Faults are acknowledged at a 0/1 edge via BI: p2103 or BI: p2104 or BI: p2105.
8...9 Reserved
10 Master control by PLC
Note:
This bit should not be set to "1" until PROFIdrive has returned an appropriate status via E_ZSW1.9 = "1".

10.1 Communication according to PROFIdrive
Remarks
0 Disable operation
Pulse inhibit is present
- -
1 Inhibit motor operation
Motoring operation as step-up converter is
inhibited.
0 Enable motor operation
Motoring operation as step-up converter is
enabled.
1 Inhibit regenerative operation
Regenerative operation is inhibited.
0 Enable regenerative operation

0/1 Acknowledge fault
- -
1 Master control by PLC
This signal must be set so that the process data
transferred via PROFIdrive is accepted and
becomes effective.
0 No master control by PLC
Process data transferred via PROFIdrive is
rejected, i.e. assumed to be zero.
