42 Program features
The table above shows the control connections of the DC/DC converter, and the default
meaning or use of the signals in the control program.
Wire sizes and tightening torques: 0.5 ... 2.5 mm
both stranded and solid wiring.
There are additional fiber optic connections from the BCU control unit to the DC/DC
converter modules (frame size R8i).
Notes:
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, R
Change of setting requires reboot of control unit.
4)
Current [0(4)...20 mA, R
Change of setting requires reboot of control unit.
5)
Must be set to ON when the converter 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 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.
