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.
z When the remote function is used, the output frequency of the inverter can be compensated for as follows:
External operation mode Frequency set by RH/RM operation plus external running frequency other
than multi-speeds
(Set "1" in Pr. 28 to select the compensation input (terminal 1).)
PU operation mode Frequency set by RH/RM operation plus PU running frequency

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. 186 (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. The frequency setting storage function stores in memory the remotely-set frequency (frequency
set by RH/RM operation) when the acceleration and deceleration signals remain off for more than
1 minute or as soon as the start signal (STF or STR) switches off. When power is switched off,
then on, operation is resumed with that value.
