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).
Use Pr. 60 to Pr. 62 (input terminal function selection) to set the signals RH, RM, RL.
* Frequency setting storage function
The remote setting frequency (frequency set by RH/RM operation) is stored in
memory.
When power is switched off once and then on again, the inverter resumes
running at this setting of output frequency. (Pr. 59="1")
Frequency as soon as the start signal (STF or STR) turns off.
Frequency when the RH (acceleration) or RM (deceleration) signal has remained off
for longer than 1 minute.
REMARKS
A restart (STF signal ON) after ON-OFF of the clear signal (RL) should be made
after more than 1 minute has elapsed. The output frequency provided when a
restart is made within 1 minute is the output frequency given after the clear signal
(RL) is turned off (multi-speed frequency).
