Description
Contact
A, B, C Alarm output
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).
RUN
Inverter
running
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.
FU
Frequency
detection
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

*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.
