Whether the UP/DOWN terminal is effective or not, the reference frequency will be
the sum of initial value of UP/DOWN and frequency setting 2. If any UP/DOWN
terminal is effective, the frequency will increase or decrease at the rate of UP/DN rate
(P3.10). And the UP/DOWN frequency range will be from the sub of frequency
setting 2 and P3.11 to the sum of frequency setting 2 and P3.11. If UP/DOWN
function terminal is not effective, the frequency reference of UP/DOWN will keep
constant. The frequency reference of UP/DOWN will be saved or not according to
the UP/DN reference saving selection P3.12, if UP/DOWN function is not effective
and STOP key has been pressed. But if UP/DOWN function is effective, the frequency
reference of UP/DOWN will keep the initial value. As shown in Fig.5-3-3.

Note: UP/DOWN Terminal is valid only when P0.01 is set to 7 and the inverter must
be in running state.
◆ If frequency setting selection (P0.03) is not 2,the frequency set mode will be
frequency setting mode 1. If frequency setting mode 1 has chosen Terminal UP/DN
(setting value is 7) function, whether the terminal UP/DN is effective or not, the
inverter will run at initial value of UP/DN (If the UP/DN reference is lower than zero,
the inverter will run at zero-speed). If any UP/DN function terminal is effective, the
UP/DN reference frequency will be changed by terminal UP/DN. And the frequency
is increased or decreased on currently operating frequency at the rate of Terminal
UP/DN rate setting (P3.10). At this time, if UP/DN is disabled, currently running
frequency will be the final UP/DN reference frequency. The frequency reference of
UP/DN will be saved according to selection of saving the UP/DN reference if
UP/DOWN function is not effective and “STOP/RESET ” key has been pressed. The
saved direction is positive. However, if UP/DOWN function is effective, the
