(24…12 AWG) and 0.5 N·m (5 lbf·in) for both stranded and
solid wiring.
As the very same control program is in use with different diode supply types, the default connections are not
applicable to them all. For example, some units have the DC link charging, some do not have it. The default
parameter settings and IO connections are valid for the version without the charging circuit.
1)
Use of the signal in the control program. When parameter 120.30 External charge enable has value Yes, the
control program reserves this I/O terminal for external charging circuit control and monitoring, and parameters
110.24 RO1 source and 110.30 RO3 source are write-protected. If the value is No, you can use the I/O terminal
for other purposes.
2)

Determines whether DICOM is separated from DIOGND (ie. common reference for digital inputs floats). See
also section Ground isolation diagram (ZCU) on page 155.
DICOM connected to DIOGND.
DICOM and DIOGND separate.
6)
Total load capacity of these outputs is 4.8 W (200 mA / 24 V) minus the power taken by DIO1 and DIO2.
7)
The function is only implemented in inverter units, not with the supply units.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.
External power supply for the control unit (XPOW)
The cabinet builder must arrange an auxiliary voltage of 24 V DC to power up the ZCU
control unit. External +24 V (2 A) power supply for the control unit is connected to terminal
block XPOW.
All digital inputs share a common ground (DICOM connected to DIOGND). This is the default setting.
