Remote Setting Function Selection (Pr. 59) - Mitsubishi Electric FR-E500 Instruction Manual

4.2.23 Remote setting function selection (Pr. 59)

Pr. 59 "remote setting function selection"
If the operator panel is located away from the
control box, you can use contact signals to
perform continuous variable-speed operation,
without using analog signals.
y By merely setting this parameter, you can use
the acceleration, deceleration and setting clear
functions of the motorized speed setter (FR-FK).
y When the remote function is used, the output frequency of the inverter can be
compensated for as follows:
External operation mode
PU operation mode

y 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 "remote setting function - yes" is selected, the functions of signals RH, RM
and RL are changed to acceleration (RH), deceleration (RM) and clear (RL). Use
Pr. 180 to Pr. 183 (input terminal function selection) to set signals RH, RM and RL.
Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration)
between 0 and the maximum frequency (Pr. 1 or Pr. 18 setting).
2. When the acceleration or deceleration signal switches on, the set frequency
varies according to the slope set in Pr. 44 or Pr. 45. The output frequency
acceleration/deceleration times are as set in Pr. 7 and Pr. 8, respectively.
Therefore, the longer preset times are used to vary the actual output
frequency.
3. If the start signal (STF or STR) is off, turning on the acceleration (RH) or
deceleration (RM) signal varies the set frequency.
4. T he frequency setting storage function stores in m em ory the rem otely-set
frequency (frequency set by R H /R M operation) w hen the acceleration and
deceleration signals rem ain off for m ore than 1 m inute or as soon as the start
signal (S T F or S T R ) sw itches off. W hen pow er is sw itched off once, then on,
operation is resum ed w ith that value.
