Table 2.2-10 Description of control circuit terminal functions (cont.)
This is a common terminal for digital input signals.
The terminal is insulated from terminals [11], [CMY].

When turning terminals [X1] to [X9], [FWD], [REV] ON/OFF using relay contacts
An example of a circuit configuration using relay contacts is shown in Fig. 2.2-18. Circuit (a) in the diagram
shows the circuit configuration when the switch is at the SINK side, and circuit (b) shows the circuit
configuration when the switch is at the SOURCE side.
Caution: Use relay contacts which do not have contact failures (high contact reliability).
(Recommended product: Fuji Electric control relay, model: HH54PW)

When turning terminals [X1] to [X9], [FWD], [REV] ON/OFF using a programmable
controller
An example of a circuit configuration using a programmable controller is shown in Fig. 2.2-19. Circuit (a) in the
diagram shows the circuit configuration when the switch (SW1) is at the SINK side, and circuit (b) shows the
circuit configuration when the switch is at the SOURCE side.
In circuit (a), terminals [X1] to [X9], [FWD], and [REV] can be turned ON/OFF by shorting/opening the open
collector transistor output of the programmable controller using an external power supply. Follow the
instructions below when using this type of circuit.
∙ Connect the + side of an external power supply insulated from the programmable controller power supply to
the [PLC] terminal.
∙ Do not connect the inverter [CM] terminal and the common terminal of the programmable controller.
(a) If switch at SINK side
(b) If switch at SOURCE side
