Possible to assign various signals to terminals [X1] to
[X3], [FWD] and [REV] using function codes. For
details, refer to Section 9.2.2 "E codes."
By factory default, FWD and REV signals are
assigned to 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.
