Description
1 changeover contact output indicates that the
inverter's protective function has activated and the
output stopped.
Fault: No conduction between B and C (conduction
between A and C)
Normal: Conduction between B and C (No conduction
between A and C)
1 changeover contact output
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.
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.
Switched low when stall prevention is
activated by the stall prevention
function. Switched high when stall
prevention is cancelled.
Switched low when an instantaneous
power failure and under voltage
protections are activated.
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.
Common terminal for terminals RUN, SU, OL, IPF, FU
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.
To set a full-scale value for
monitoring the output frequency and
the output current, set Pr.56 and
Pr.158.
With the PU connector, communication can be established through RS-485.
