9. Explanation of I-Group Function
100
The FW terminal and RV terminal become redundant when the 3 wire control terminal is as
follows:
STA
STP
F/R
Output frequency
ON
ON
Forward
Reverse
Fig. 9- 22 The output waveform of the 3 Wire(3-Wire) input function
Note) If STP terminal function is set, FW and REVS terminal function is invalid.
9.2.15
PID function selection and PIDC
(1) When using this function turn on the terminal in the case that you invalidate this function after
assigned 21 (PID ) to intelligent input terminal in the case of switching valid / invalid of this
function with the outside signal
(2) PIDC is the function to clear integral value of PID action.
(3) Assign 22(PIDC) to an intelligent input terminal.
(4) It is cleared whenever the PIDC terminal is turned ON.
(5) Don't turn absolutely ON PID terminal during PID action, because there is a possibility of
overcurrent trip.
(6) Turn ON PIDC terminal after turning OFF PID action.
Note) Please refer to PID control part for details.
9.2.16 UP/DOWN
function(UP,DOWN,UDC)
(1) The Inverter output frequency can be changed with the UP and DWN intelligent input
terminals.
(2) Assign 24 (UP) and 25(DWN), 26(UDC) to two of the intelligent input terminals 1~8.
(3) This function is valid only when the frequency command selection F010 is set to 01 or 02.
However, when 01 (control terminal) is set, this can only be used for multi-speed operation.
(4) This function will not operate when the external analog frequency command or the jogging
operation is used.
(5) Acceleration time operates according to F007, F008 when UP/DOWN terminal is ON.
(6) To change 1 /2 /3 control, assign 08(SET)/17(SET3) to an input terminal, change with
SET/SET3 terminal.
(7) It is possible for the Inverter to retain the frequency setting value from the UP/DOWN
terminals.
Parameter I048 switches the memory ON or OFF. It is also possible to clear the memory and
return to the original set frequency.
