• Tightening torques: 0.5…0.6 N·m (0.4 lbf·ft)
Notes
1)
Current [0(4)…20 mA, R
in
< 500 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] input as
selected with parameter 12.15 AI1 unit selection .
2)
Current [0(4)…20 mA, R
in
= 100 ohm] or voltage[ 0(2)…10 V, R
in
> 200 kohm] input as
selected with parameter 12.25AI2 unit selection .
3)
Total load capacity of the auxiliary voltage 24V (X2:10) = 6.0 W (250 mA / 24 V)
- User can use this source for either of theI/O connections (DI1... DI2- RO1 or DI3...DI6 -
RO2~RO3).
4)
Connected with jumpers at the factory.
5)
Applicable for R0~R2 frames only.
6)
Use shielded twisted-pair cables for digital signals.
7)
Ground the outer shield of the cable 360 degrees under the grounding clamp on the
grounding shelf for the control cables.

Position Description Switch
Term & BIAS off
1
Modbus link termination and biasing voltages to
the bus.
Set to ON position when the drive is the last unit
on the link.

Term & BIAS on
ON
BUS not terminated ( default )
1
Modbus link termination. Must be set to the ter-
minated (ON) position when the drive is the first
or last unit on the link. S100

BIAS off ( default )
1
Switches on the biasing voltages to the bus. One
(and only one) device, preferably at the end of
the bus must have the bias on. S200
