Frequency setting by external terminals
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
(1) Remote setting function
⋅ Use Pr. 59 to select whether the remote setting function is used or not and whether the frequency setting storage
function in the remote setting mode is used or not.
When Pr. 59 is set to any of "1 to 3" (remote setting function valid), the functions of the RH, RM and RL signals are
changed to acceleration (RH), deceleration (RM) and clear (RL).
⋅ When the remote function is used, the output frequency of the inverter can be compensated for as follows:
External operation
.. Frequency set with RH and RM operation + external operation frequency other than multi-speed
(PU operation frequency when
Pr. 79
= "3" (external, PU combined)) and terminal 4 input.
(When making analog input compensation, set "1" in Pr. 28 Multi-speed input compensation
selection.
When Pr. 28 is set to "0" and acceleration/deceleration is made to reach the set frequency of
the analog voltage input (terminal 2 or terminal 4) by RH/RM, the auxiliary input by terminal 1
becomes invalid.)
PU operation ...........Frequency set by RH/RM operation + 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.
