Turning on or off [X1], [X2], [X3], [FWD], or [REV] using a relay contact
Figure 2.15 shows two examples of a circuit that turns on or off control signal input [X1],
[X2], [X3], [FWD], or [REV] using a relay contact. Circuit (a) has a connecting jumper
applied to SINK, whereas circuit (b) has one that is applied to SOURCE.
Note: To configure this kind of circuit, use a highly reliable relay
(Recommended product: Fuji
control relay Model HH54PW.)
(a) With a jumper applied to SINK
(b) With a jumper applied to SOURCE

Turning on or off [X1], [X2], [X3], [FWD], or [REV] using a programmable logic
controller (PLC)
Figure 2.16 shows two examples of a circuit that turns on or off control signal input [X1],
[X2], [X3], [FWD], or [REV] using a programmable logic controller (PLC). Circuit (a) has a
connecting jumper applied to SINK, whereas circuit (b) has one that is applied to
SOURCE.
In circuit (a) below, short-circuiting or opening the transistor's open collector circuit in the
PLC using an external power source turns on or off control signal [X1], [X2], [X3], [FWD],
or [REV]. When using this type of circuit, observe the following:
- Connect the + node of the external power source (which should be isolated from the
PLC's power) to terminal [PLC] of the inverter.
- Do not connect terminal [CM] of the inverter to the common terminal of the PLC.
(a) With a jumper applied to SINK
(b) With a jumper applied to SOURCE
Digital input

SINK/SOURCE (jumper switch)."
