Remote Setting Function (Pr. 59) - Mitsubishi Electric FR-F740-00023-EC Instruction Manual

Remote setting function (Pr. 59)

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.

(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 + external running frequency or PU running frequency
(other than multi-speed).
(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.)
PU operation ............. Frequency set by RH/RM operation + PU running frequency
(2) Frequency setting storage
⋅ The frequency setting storage function stores the remotely-set 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.)
