Frequency setting storage condition
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 cut off and turned on again, the inverter can start running again at
the remote-set frequency (10-11=1).
<Frequency setting storage condition>
1. It is the frequency when the start signal (STF/STR) is “off”.
2. When the signal RH (acceleration) and RM (deceleration) are both “off” and “on”, the remote-set frequency is
stored every minute. (Current frequency set value and the last frequency set value are compared ever minute. If
they are different, then the current frequency set value is written in the memory. If RL is on, write-in will unavail-
able).

1. The frequency can be varied by RH (acceleration) and RM (deceleration) between 0 and (the maximum frequency – frequency
set by the main speed). The output frequency is limited by 01-00.
2. When the acceleration or deceleration signal is “on”, the acceleration / deceleration time will be determined by the set value of
01-06 (the first acceleration time) and 01-07 (the first deceleration time)
3. When RT signal is “on” and 01-22≠99999 (the second acceleration time), 01-23≠99999 (the second deceleration time), the
acceleration / deceleration time will be determined by the set value of 01-22 and 01-23.
4. When the start signal (STF/STR) is “off” and RH (acceleration) / RM (deceleration) is “on”, the target frequency will also
change.
5. When the start signal (STF/STR) becomes “off”, make the frequency setting storage function invalid (10-11=2, 3) if the fre-
quency has to be changed continuously through RH/RM. If the frequency setting storage function is valid (10-11=1), the life of
EEPROM will be shortened by frequent EEPROM data writing.
6. RH, RM and RL mentioned in this chapter are function names of “multi-function digital input terminal”. If the functions of the
terminals are changed, other functions are likely to be affected. Please verify the functions of the terminals before changing
the options and functions of the multi-function digital input terminal (please refer to 03-00~03-05, 03-06 and 03-09). For wiring,
please refer to Section 3.3.
