7.14.2 Switch-off behavior
The drive’s 24 V supply must remain constant. Hardware Enable input disables the power

The enable/disable button in WorkBench issues a drv.dis command internally to the drive.
See WorkBench Online Helpfor configuring inputs and software commands. Sometimes this
enable signal is called "Software Enable" (SW-Enable).
DRV.DISMODE DRV.DISMODE controls the behavior of the drv.dis command issued
through WorkBench, or terminal, or fieldbus. Consult the WorkBench
Online Helpfor configuring.
