Remote setting function (Pr. 59)

Even if the operation panel is located away from the enclosure, you can use contact signals to perform
Pr. 58
continuous variable-speed operation, without using analog signals.

(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 by RH/RM operation
PU operation .............Frequency set by RH/RM operation + PU running frequency
(2) Frequency setting storage
⋅ The frequency setting storage function stores the remote setting frequency (frequency set by RH/RM operation)
into the memory (EEPROM). When power is switched off once, then on, operation is resumed with that output
frequency value. (Pr. 59 =1)
<Frequency setting storage conditions>
⋅ Frequency at the point when the start signal (STF or STR) turns off
⋅ The remotely-set frequency is stored every one minute after one minute has elapsed since turn off (on) of
both the RH (acceleration) and RM (deceleration) signals. (The frequency is written if the present
frequency setting compared with the past frequency setting every one minute is different. The state of the
RL signal does not affect writing.)

(When making analog input compensation, set "1" to 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.)
