Remote Setting Function (Pr. 59) - Mitsubishi Electric 700 Series Instruction Manual

5.7.2

Remote setting function (Pr. 59)

Continuous variable-speed operation can be performed using acceleration and deceleration signals.
By simply setting this parameter, you can use the acceleration, deceleration and setting clear functions of the
motorized speed setter (FR-FK).

(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 using the remote setting function, following frequencies can be compensated to the frequency set by RH and RM
operation according to the operation mode.
During FL remote communication operation .....................FL remote communication frequency command other than for
During PU operation..........................................................PU operation 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>
Remote setting frequency is saved in the following timings:
When the start signal (STF or STR) turns OFF
Every minute after turning OFF (ON) the RH (acceleration) and RM (deceleration) signals together. (The frequency
is overwritten if the latest frequency is different from the previous frequency when comparing the two. The state of
the RL signal does not affect writing.)
When the power supply changes to the 24V external power supply while the start signal (STF or STR) is ON. (When
the operation panel indication shows "EV.")
