Frequency setting by external terminals
4.7.3 Input compensation of multi-speed and remote setting (Pr. 28)
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 201)
4.7.4 Remote setting function (Pr. 59)
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 201)
* External operation frequency (other than multi-speed) or PU running frequency
By inputting the frequency setting compensation signal (terminal 1, 2), the speed (frequency) can be compensated
for relative to the multi-speed setting or the speed setting by remote setting function.

Even if the operation panel is located away from the enclosure, you can use contact signals to perform
continuous variable-speed operation, without using analog signals.
By simply setting this parameter, you can use the acceleration, deceleration and setting clear functions of
the motorized speed setter (FR-FK).
