92 Control unit of frames R6 to R9
Notes:
1)
Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] input selected with jumper J1. Change of
setting requires reboot of control unit.
2)
Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] input selected with jumper J2. Change of
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
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
connectors, see section
Technical data on page 95 .


External power supply for the control unit
Ex24 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).

Description Positions
J1
(AI1) Determines whether analog input AI1 is used as a current or
voltage input. Current (I)
Voltage (V)
J2
(AI2) Determines whether analog input AI2 is used as a current or
voltage input. Current (I)

J3 Drive-to-drive link termination. Must be set to terminated
position when the drive is the last unit on the link. Bus is terminated.
Bus is not terminated.
J6 Common digital input ground selection switch. Determines
whether DICOM is separated from DIOGND (ie, common
reference for digital inputs floats). See the
Ground isolation
diagram on page 97 .
