Inhibit motor operation

1

Inhibit motor operation

BI: p3532

 

 

 

Motoring operation as step-up converter is

 

 

 

 

inhibited.

 

 

 

0

Enable motor operation

 

 

 

 

Motoring operation as step-up converter is

 

 

 

 

enabled.

 

 

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

1

Inhibit regenerative operation

BI: p3533

 

 

 

Regenerative operation is inhibited.

 

 

 

0

Enable regenerative operation

 

 

 

 

Regenerative operation is enabled.

 

 

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

 

BI: p2103

 

Note:

 

 

 

 

 

Faults are acknowledged at a 0/1 edge via BI: p2103 or BI: p2104 or BI: p2105.

Control via PLC

BI: p0854

 

 

 

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.
