PARAMETERS
4.11.3 Input compensation of multi-speed and remote setting (Pr. 28)
4.11.4 Remote setting function (Pr. 59)
* 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.

REMARKS
⋅ Select the terminal (terminal 1, 2) used for compensation input voltage (0 to ±5V, 0 to ±10) using Pr. 73 Analog input selection.
⋅ When using terminal 1 for compensation input, set "0" (initial value) in Pr. 868 Terminal 1 function assignment.

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).
