4.2.24 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.
variable-speed operation, without using analog signals.
z
By merely setting this parameter, you can use the acceleration, deceleration and setting clear functions of
the motorized speed setter (FR-FK).
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
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* 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).
RH, RM and RL are changed to acceleration (RH), deceleration (RM) and clear (RL).
* Frequency setting storage function
The remote setting frequency (frequency set by RH, RM operation) is stored into memory. When power is
switched off once, then on again, operation is resumed at this setting of the output frequency. (Pr. 59=1)
<Frequency setting storage condition>

<Frequency setting storage condition>
•
Frequency at the time when the start signal (STF or STR) has switched 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 value compared with the past frequency value every one minute is different. ) (The state of the
RL signal does not affect writing. )
