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.
By merely setting this parameter, you can use the acceleration, deceleration and setting clear functions of
z
the motorized speed setter (FR-FK).
When the remote function is used, the output frequency of the inverter can be compensated for as follows:

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 terminals RH, RM and RL are changed to acceleration (RH), deceleration (RM)
and clear (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. 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.
