Using a relay contact to turn [X1], [X2], [X3], [X4], [X5], [FWD], or [REV] ON or OFF
Figure 2.23 shows two examples of a circuit that uses a relay contact to turn control signal input [X1],
[X2], [X3], [X4], [X5], [FWD], or [REV] ON or OFF. In circuit (a), the slide switch SW1 has been turned
to SINK, whereas in circuit (b) it has been turned to SOURCE.
Note: To configure this kind of circuit, use a highly reliable relay
(Recommended product: Fuji control relay Model HH54PW.)
(a) With the switch turned to SINK
(b) With the switch turned to SOURCE

Using a programmable logic controller (PLC) to turn [X1], [X2], [X3], [X4], [X5], [FWD], or
[REV] ON or OFF
Figure 2.24 shows two examples of a circuit that uses a programmable logic controller (PLC) to turn
control signal input [X1], [X2], [X3], [X4], [X5], [FWD], or [REV] ON or OFF. In circuit (a), the switch SW1
has been turned to SINK, whereas in circuit (b) it has been turned 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 the switch turned to SINK
(b) With the switch turned to SOURCE
