Remote setting function
1. Whether the remote setting function is valid and whether the frequency setting storage function
in the remote setting mode is used or not is selected by P.61.
Set P.61=1~3 (remote setting function is valid), the function of terminals RM, RH and RL are
changed to acceleration (RH), deceleration (RM) and clear (RL). As shown in the following

2. During remote setting, the output frequency of the inverter is:
(frequency set by RH/RM operation
＋
external set frequency other than multi-speeds/PU set
frequency)
•
Frequency setting storage function
1. The frequency setting storage function is to storage in memory (EEPROM) the remote-set
frequency (frequency set by RH/RM opertion). Once the power supply is cut off, then on, the
inverter can start running again at the remote-set frequency (When P.61=1).
<Frequency setting storage condition>
(1). The frequency when the start signal (STF/STR) is
‘
off
’
(2). When the signals RH(acceleration) and RM(deceleration) are both
‘
off
’
(
‘
on
’
), the remote-set
frequency is storaged each minute(The current frequency set value and the last frequency set
value are compared each minute. If they are different, then the current frequency set value is
written in the memory. If RL is on, write will not perform.).
