7: Setting frequency selection

FC frequency setting options: If the "FC frequency setting options" is "enable function terminals", the
frequency set point is determined by P0.06 running frequency setting combination 2; if this function terminal
is inactive, the frequency set point is determined by P0.05 running frequency setting combination 1. During
inverter operation, frequency setting mode can be switched through FC terminal to control the inverter output
frequency flexibly.
8~9:Jog operation signal (FJOG/RJOG)
 If setting is 8 or 9, this terminal can enable jog operation, when inverter didn't start up by other running
command. FJOG is for jog forward command and RJOG is for jog reverse command, as shown in
Figure.5-3-2. The defined Jog function of terminal isn't limited by run command mode selection (P0.07).
When Jog frequency, and jog Acc/Dec time can be defined in P2.00~P2.02.
Operation Freq.(Hz)
10~12: UP/DOWN
 When P0.05 is 4, the frequency is set to 1 +2
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 (P3.16). And the UP/DOWN frequency range will be from the sub of
frequency setting 2 and P3.17 to the sum of frequency setting 2 and P3.17. 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
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 Figure.5-3-3.
 When P0.05 is not 4, the frequency is set to 1 and terminal is UP / DN;
At the beginning of the running, if UP / DOWN terminals are all inactive or are active, then the inverter runs
at the initial set point of UP / DOWN (if the value is negative, the inverter runs at 0 frequency); if one
terminal of UP / DOWN is active, then the set frequency is controlled by UP / DOWN terminal, increase or
decrease on the basis of the current speed at the speed of terminal UP / DOWN (P3.16). At this point, if the
UP / DOWN terminal is inactive, then the running frequency at this time is the set frequency. When the UP /
DOWN terminal is inactive, press STOP key, save the current set frequency to the given value of UP /
DOWN in the method determined by the function code P3.18 with the sign as positive. When the UP /
DOWN terminal is active, then the given value of UP / DOWN is the initial value as shown in Fig. 5-3-4.
