Control units of the drive 99
Notes:
The wire size accepted by all screw terminals (for both stranded and solid wire) is
0.5…2.5mm
2
(24…12 AWG). The torque is 0.5 N·m (5 lbf·in).

2)
See chapter Safe torque off function.
3)
0 = Acceleration/deceleration ramps defined by parameters 23.12/23.13 in use.
1 = Acceleration/deceleration ramps defined by parameters 23.14/23.15 in use.
4)
Constant speed 1 is defined by parameter 22.26.
5)
See section DIIL input (page 100).
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; in practice, selects whether the digital inputs are used in current
sinking or sourcing mode). See also Ground isolation diagram.
DICOM=DIOGND ON: DICOM connected to DIOGND. OFF: DICOM and DIOGND
separate.

External power supply for the control unit (XPOW)
The BCU-x2 is powered from a 24 V DC, 2 A supply through terminal block XPOW. A
second supply can be connected to the same terminal block for redundancy.
DI6 as a PTC sensor input
A PTC sensor can be connected to this input for motor temperature measurement as
follows. The sensor can alternatively be connected to FEN-xx encoder interface module.
Do not connect both ends of the cable shield directly to ground. If a capacitor cannot be
used at one end, leave that end of the shield unconnected. See the firmware manual for
parameter settings.
