The table above shows the control connections of the supply unit, and the default
meaning or use of the signals in the control program.
The wire size accepted by all screw terminals (for both stranded and solid wire) is
2
0.5 ... 2.5 mm (24...12 AWG). Tightening torque is 0.45 N·m (4 lbf·in).
Notes:
As the very same control program is in use with different diode supply types, the default connections
are not applicable with them all. For example, some units have the DC link charging, some do not have
it. The default parameter settings and I/O connection are valid for the version without the charging
circuit.
1)
Use of the signal in the control program. The use is fixed and it cannot be changed by a parameter.
2)
Default use of the signal in the control program. The use can be changed by a parameter. For the
delivery-specific use, see the delivery-specific circuit diagrams.
3)
Current [0(4)...20 mA,
AI1. Change of setting requires reboot of control unit.
4)
Current [0(4)...20 mA,
AI2. Change of setting requires reboot of control unit.
5)
Must be set to ON when the drive is the first or last unit on the drive-to-drive (D2D) link.
6)
Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and
DIO2.
7)
Determines whether DICOM is separated from DIOGND (ie. common reference for digital inputs
floats).
DICOM = DIOGND ON: DICOM connected to DIOGND. OFF: DICOM and DIOGND separate.
8)
This input is used in inverter units only, not in supply units. This input only acts as a true Safe torque
off input in control units controlling an inverter unit. In other applications (such as a supply or brake
unit), de-energizing the IN1 and/or IN2 terminal will stop the unit but not constitute a true safety
function.
