Function
Common terminal of contact input signals.
When the frequency setting signal is provided with voltage or
current, this changes over the input signal to be used.
AUT-CM On = Selects current input (4 to 20
AUT-CM Off = Selects voltage input and frequency setting input,
Forward command via FWD-CM (closed). Reverse command via
REV-CM (closed). When FWD-CM is closed and REV-CM is closed
at the same time, the inverter will decelerate and stop (only when
Function Code 41 is set inactive).
Motor will coast-to-stop with BX-CM (closed). No alarm signal will be
output. If BX-CM is opened while FWD or REV closed , the inverter
will start to operate because a RUN command is present.
Eight
frequency settings can be made with the
combinations of ON and OFF of each terminal.
By changing Function Code 42 to YES, the
and X2 terminals are
changed from multi-step speed commands to increase and
decrease commands. The increase and decrease commands
simulate a motorized speed pot.
By changing
Code 41 to YES, the X3 terminal is changed
from a multi-step speed command to a momentary pushbutton
common input for momentary START/STOP commands. With X3-
CM closed, FWD and REV signals input by a pulse signal (pulse
width of 50
or greater) can be self-sealed.
(closed),
(closed),
(closed) are the
second, third, and fourth types of acceleration/deceleration time
selections. NOTE: When there is no input to
operation is
by normal first acceleration/deceleration time.
With THR-CM open, OH2 trip will occur and motor will coast-to-stop.
NOTE: With no external thermal relay or external braking resistor
thermostat, the THR-CM terminals must be
or the inverter
not operate.
Faults are reset when a momentary contact is made between the
RST-CM terminals for more than 0.1 seconds.
NOTE: If there is an input to the
or REV terminals, the unit
not RESET.
