2. At the remote setting, the output frequency of the inverter is:
Target Frequency set by external terminals:
Frequency set by RH/RM operation
+
external set frequency other than multi-speeds
Target Frequency set by operation panel:
PU set fre external set frequency other than multi-speeds
• Frequency setting storage function
The frequency setting storage function is to store the remote-set frequency (frequency set by
RH/RM operation) in memory (EEPROM). Once the power supply is shut off, 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 either off (or on), the remote-set
frequency is stored per minute. The current frequency set value and the last frequency set value
is compared at each minute. If they are different, then the current frequency set value is written
in the memory. No writing if RL is on.
Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration) between 0 and the maximum
frequency. The upper limit of the setting frequency is the maximum frequency, as shown below:
2. When the acceleration or deceleration signal is on, the output frequency acceleration/deceleration times
are determined by P.7 (first acceleration time) and P.8 (first deceleration time) (When RT is ‘off’).
3. When P.44≠9999 (the second acceleration time) and P.45≠9999 (the second deceleration time), the
acceleration/deceleration times are due to P.44, P.45.
4. When the start signal (STF/STR) is off, the target frequency will also change if RH (acceleration)/RM
(deceleration) is on.
5. When the start signal (STF/STR) is changed from on to off, or the frequency is continually changed by
RH/RM, make the frequency setting storage function invalid (P.61=2, 3).
6. If the frequency setting storage function is valid (P.61=1), the life of the EEPROM will be shortened
because of frequent writing of frequency onto EEPROM.
7. Signals RH, RM and RL are determined by P.80~P.84, P.86. If the functions of the terminals are changed,
other functions are likely to be affected. Please make sure that the functions of the terminals before
changing the functions.
