Control units of the drive 341
The table above shows the control connections of the unit, and the default meaning or use
of the signals in the control program. Most I/O connections are reserved and wired for the
internal use at the factory. Do not change the connections.
Wire sizes and tightening torques: 0.5 … 2.5 mm
2
(24…12 AWG) and 0.5 N·m (5 lbf·in) for
both stranded and solid wiring.
There are additional fiber optics connections from the BCU control unit to the D8T
modules.
Notes:
1)
See section Drive-to-drive link (XD2D) (page 345).
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)
Use of the signal in the control program. The use is fixed and it cannot be changed by a parameter.
4)
This input only acts as a true Safe torque off input in control units controlling a motor. 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.
5)
Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and DIO2.
6)
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.
7)
Current [0(4)…20 mA, R

Change of setting requires reboot of control unit.
