*1: Low indicates that the open collector output transistor is on (conducts). High
indicates that the transistor is off (does not conduct).
*2: Not output during inverter resetting.
Terminal
Name
Change-over contact output indicating that
the output has been stopped by the inverter
protective function activated. 230VAC 0.3A,
30VDC 0.3A. Alarm: discontinuity across B-
C (continuity across A-C), normal:
continuity across B-C (discontinuity across
A-C).
Switched low when the inverter output
frequency is equal to or higher than the
starting frequency (factory set to 0.5Hz,
variable). Switched high during stop or DC
injection brake operation (*1).
Permissible load 24VDC 0.1A.
Switched low when the output frequency
has reached or exceeded the detection
frequency set as appropriate. Switched
high when below the detection frequency
(*1).
Permissible load 24VDC 0.1A
Common to the RUN and FU terminals
One selected from output
frequency, motor current
and output voltage is output
(*2). The output signal is
proportional to the
magnitude of each
monitoring item.
With the operation panel connector, communication can
be made using the RS-485 protocol.
