Safe torque offXSTO
XSTO: Factory connection. Both circuits (power module, control unit) must
be closed for the drive to start (STO1 and STO2 must be connected to OUT).
Refer to chapter The Safe torque off function (page 307).

Ground selection switch. Determines whether DICOM is separated from
DIOGND (ie. common reference for digital inputs floats). ON: DICOM con-
nected to DIOGND. OFF: DICOM and DIOGND separate.
