122 Control unit of frames R6 to R9
Notes:
1)
Current [0(4)...20 mA, R
= 100 ohm] or voltage [ 0(2)...10 V, R
in
setting requires reboot of control unit.
2)
Current [0(4)...20 mA, R
= 100 ohm] or voltage [ 0(2)...10 V, R
in
setting requires reboot of control unit.
3)
Total load capacity of these outputs is 4.8 W (200 mA / 24 V) minus the power taken by DIO1 and DIO2.
4)
0 = open, 1 = closed
DI4
Ramp times according to
0
Parameters 23.12 and 23.13
1
Parameters 23.14 and 23.15
5)
Constant speed 1 is defined by parameter 22.26.
Further information on the usage of the connectors and jumpers is given in the sections below. For the technical data of the

Jumpers and switches
Jumper/
Switch
J1
Determines whether analog input AI1 is used as a current or
voltage input.
(AI1)
J2
Determines whether analog input AI2 is used as a current or
voltage input.
(AI2)
J3
Drive-to-drive link termination. Must be set to terminated
position when the drive is the last unit on the link.
J6
Common digital input ground selection switch. Determines
whether DICOM is separated from DIOGND (ie, common
reference for digital inputs floats). See the
diagram
on page 127.
External power supply for the control unit
External +24 V (2 A) power supply for the control unit can be connected to terminal block
XPOW. Using an external supply is recommended if
•
the control unit needs to be kept operational during input power breaks, for example,
due to uninterrupted fieldbus communication
•
immediate restart is needed after power breaks (that is, no control unit power up delay
is allowed).
See also the firmware manual, parameter 95.04.
