The inverter will be damaged if power is applied to the inverter output terminals (U, V, W). Never perform such wiring.
indicates that terminal functions can be selected fromPr. 178 to Pr. 196 (I/O terminal function selection)
*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 reset.
Terminal Name
Changeover contact output indicates that the inverter protective function has activated and the
output stopped. Abnormal: No conduction across B-C (Across A-C Continuity), Normal: Across
B-C Continuity (No conduction across A-C) Contact capacity: 230VAC 0.3A (Power factor=0.4)
30VDC 0.3A
1 changeover contact output Contact capacity: 230VAC 0.3A (Power factor=0.4) 30VDC 0.3A
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.
*1
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. *2
The output signal is proportional to the magnitude of the
corresponding monitoring item.
With the PU connector, communication can be made through RS-485.
