Remote setting function

Even if the operation panel is located away from the enclosure, contact signals can be used to perform continuous variable-
speed operation, without using analog signals.

Description
The inverter accelerates the motor in the forward or reverse direction up to
the main speed or to the frequency stored by the remote setting function.
The set frequency increases according to the Pr.44 setting.
The set frequency decreases according to the Pr.45 setting.
The set frequency is cleared and the main speed is applied.
The setting of the main speed is used as a base. The main speed is
increased by the RH signal and decreased by the RM signal.
Decreased according to
the Pr.45 setting
