Description
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.
With the PU connector, communication can be made through RS-485.
(for connection on a 1:1 basis only)
