Bit Meaning
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.
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".
