Analog input
[X1] Digital input 1 (1) The various signals such as coast-to-stop, alarm from external equipment, and mul-
tistep frequency selection can be assigned to terminals [X1] to [X3], [FWD] and [REV]
by setting function codes E01 to E03, E98, and E99. For details, refer to Chapter 5,
Section 5.2 “Overview of Function Codes.”
(2) Input mode, i.e. Sink/Source, is changeable by using the built-in jumper switch.
(3) Switches the logic value (1/0) for ON/OFF of the terminals between [X1] to [X3],
[FWD] or [REV], and [CM]. If the logic value for ON between [X1] and [CM] is 1 in
the normal logic system, for example, OFF is 1 in the negative logic system and
vice-versa.

Common terminal for digital input signals
TIP: As shown in Figure 2.15, the digital input terminals
[X1] to [X3], [FWD] and [REV] can be switched on or off
with the open collector transistor outputs by connecting
the power input (+) of the external device, such as a
PLC, to terminal [PLC] that supplies power to the device.
To do so, switch the jumper to SINK.
NOTE: Do not connect terminal [CM] of the drive to the
common terminal of a programmable controller.
NOTE: To switch terminals [X1] through [X3], [FWD] and
[REV] on or off with contact input, use reliable contacts.
