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.

 Remote setting function
• Use
to enable/disable the remote setting function and enable/disable the frequency setting storage function during
Pr.59
remote setting.
• When
≠ "0" (remote setting function valid), the functions of the RH, RM and RL signals are changed to acceleration
Pr.59
(RH), deceleration (RM) and clear (RL).

 Acceleration/deceleration operation
• When the acceleration (RH) signal is turned ON, the set frequency increases. The increased speed at this time is
determined by the setting of
set frequency and run the motor at the frequency at that time.
• When the deceleration (RM) signal is turned ON, the set frequency decreases. The decreased speed at this time is
determined by the setting of
the same as
Pr.44
frequency at that time.
