command
The following features can be set to terminals [X1] -
[X3], [FWD] and [REV] and the commands function
according to the input signals at the terminals.
The commands (FWD) and (REV) are factory setting
assigned at terminals [FWD] and [REV],
respectively.
Common features
•
Sink/Source switching feature:
Sink and source can be switched by using the
built-in jumper switch.
•
Normal/negative logic input switching feature:
Switches the logic value (1/0) for ON/OFF of
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.

[CM] Digital common Common for digital input signals
(Isolated from terminals [11] and [Y1E].)
As shown in Figure 8.3, you can switch 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 PLC to terminal [PLC] that supplies power to the device.
To do so, switch the jumper to SINK.
Do not connect terminal [CM] of the inverter to a common terminal of a programmable
controller.
Figure 8.3 External Power Supply Connection
To turn terminals [X1] to [X3], [FWD], and [REV] ON or OFF with relay contact input,
use reliable contacts free from poor contact.
Recommended relay: Fuji's control relay
