If the jumper switch is set at SINK
As shown in Figure 2.15, you can
turn digital input terminals [X1] to
[X3], [FWD], and [REV] on or off by
open collector transistor outputs if
you connect the power input (+) of
the external device such as a
programmable controller to termi-
nal [PLC] that supplies power to
the device.
To do so, switch the jumper to
SINK.

Connecting a programmable controller to the inverter
Figure 2.16 (b) Programmable Controller Connection
Do not connect terminal [CM] of the inverter to a common terminal of a programmable
controller.
To turn terminals [X1] to [X3], [FWD], and [REV] on or off with relay contact input, use
reliable contacts free from poor contact.
