Digital input/output groundDIGND8
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.

1)
Must be set to ON when the unit is the first or last unit on a drive-to-drive (D2D) link. On intermediate units, set
termination to OFF (1).
2)
Default use of the signal in the control program. The use can be changed by a parameter. See also the delivery-specific
circuit diagrams.
3)
This input only acts as a true Safe torque off input in inverter units. In other applications (such as DC/DC converter
unit), de-energizing the STO1 and/or STO2 terminal will stop the unit but not constitute a SIL/PL classified safety
function.
4)
Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and DIO2.
