Terminal name
Forward rotation When the FW signal is ON, the motor runs
command terminal forward. When it is OFF, the motor decelerates
and stops.
Multi-function input Select 8 functions from among the 61 functions
and allocate them to terminals 1 to 8.
Note: Only terminals 1 and 3 can be used for the
Multi-function input The sink and source logic for contact input can
common be switched by connecting a short-circuit bar on
the control terminal block.
Short-circuiting P24 and PLC ⇒ Sink logic,
Short-circuiting PLC and CM1 ⇒ Source logic
To activate contact input via an external power
supply, remove the short-circuit bar and
connect CM1 terminal to the external interface
circuit.
Multi-function output Select 5 functions from among 45, and allocate
them to terminals 11 through 15.
If an alarm code is selected in C062, terminals
11 to 13, or terminals 11 to 14 always output an
alarm factor code (e.g. Inverter trip). The signal
between each terminal and CM2 always
corresponds to the sink or source logic.
Multi-function output Common terminals for multi-function output
common terminals 11 to 15.
Relay output Select the desired functions from among 45
functions, and allocate them. SPDT contact
output.
By factory default, the relay output (AL2, AL1)
contact selection (C036) is set at NC contact
between AL2-AL0, and NO contact between
Relay output
AL1-AL0.
