Bit Meaning Comments BICO
0/1 ON
Pulse enable possible
0 ON/OFF1
0 OFF1
Reduce DC link voltage via ramp (p3566), pulse
inhibit/line contactor open
BI: p0840
1 No OFF2
Enable possible
OFF2
0 OFF2
Immediate pulse cancellation and power-on
inhibit
BI: p0844 1
Note:
Control signal OFF2 is generated by ANDing BI: p0844 and BI: p0845.

1 Enable operation
Pulse enable is present
3 Enable operation
0 Disable operation
Pulse inhibit is present

1 Inhibit motor operation
Motoring operation as step-up converter is
inhibited.
Inhibit motor operation
0 Enable motor operation
Motoring operation as step-up converter is
enabled.
BI: p3532 5
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.
1 Inhibit regenerative operation
Regenerative operation is inhibited.
Inhibit regenerating
0 Enable regenerative operation
Regenerative operation is enabled.
BI: p3533 6
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).
Acknowledge error
0/1 Acknowledge error BI: p2103 7
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.
10 Master ctrl by PLC
0 No control via PLC
Process data transferred via PROFIdrive is
rejected - i.e. it is assumed to be zero.
