running
Switched low when the inverter output frequency is equal to or
higher than the starting frequency (initial value 0.5Hz). Switched
high during stop or DC injection brake operation.

Permissible load
24VDC (27VDC
maximum) 0.1A
(A voltage drop is
2.8V maximum
when the signal is
ON.)
Low is when the
open collector
output transistor is
ON (conducts).
High is when the
transistor is OFF
(does not conduct)

SU
Up to
frequency
Switched low when the output
frequency reaches within the range of
±10% (initial value) of the set frequency.
Switched high during acceleration/
deceleration and at a stop.

warning
Switched low when stall prevention is
activated by the stall prevention
function. Switched high when stall
prevention is cancelled.

IPF
Instantaneous
power failure
Switched low when an instantaneous
power failure and under voltage
protections are activated.

Frequency
detection
Switched low when the inverter output
frequency is equal to or higher than the
preset detected frequency and high
when less than the preset detected
frequency.

For meter
Select one e.g. output frequency from
monitor items. Not output during
inverter reset.
The output signal is proportional to the
magnitude of the corresponding
monitoring item.
Use Pr. 55, Pr. 56, and Pr. 866 to set full
scales for the monitored output
frequency, output current, and torque.
