12. 1-00~05=15, 16: UP / DOWN Function (Actual ACC/DEC time is based on the setting):
(1)00-05/00-06 = 3 to use the UP/DOWN Function. The other frequency signals are ignored.
(2)Set 01-07=0 and 01-08=0. The inverter accelerates to the preset value of 03-01 when in RUN,
and then it maintains a constant speed. As the inverter receives either the UP/DOWN
command, it will accelerate / decelerate until the command is released. The inverter runs at
the speed setting at the time of release. The inverter will ramp stop or Free-Fun stop which is
determined by the 04-01 as long as the inverter receives the STOP command. The frequency
at Stop time will be stored in03-01. The UP/DOWN KEY is invalid when the inverter is
stopped. It is necessary to use the Keypad to modify the preset parameters.
(3)Set 01-08 = 1, the inverter will operate from 0Hz when the operation terminal is ON. The
action of UP/DOWN is the same as above. The inverter will ramp stop or free-run stop as
determined by 04-01 setting when it receives the Stop Command. The next operation will
start at 0 Hz.
(4)UP/Down Signals simultaneously pressed are invalid
(5)01-07≠ 0, the inverter accelerates to the setting of 03-01 and maintains speed. When the
UP/Down terminal is on, setting frequency is the value 03-01±01-07, and the inverter will
accelerate/ decelerate to frequency 03-01. The upper frequency limit and lower frequency
limit also restrict the operation. If the signal of UP/ DOWN is maintained over 2 seconds, the
inverter will begin to accelerate/ decelerate. If 01-07=0, the operation is the same, until the
UP/ DOWN signal is released. Please refer to the time diagram of 01-07.
13. 1-00~05=17 Main/sub Frequency Command Selection
When External multifunction input terminals are off, the inverter Frequency Command is
operated by 00-05.
When External multifunction input terminals are on, the inverter Frequency Command is
operated by 00-06.
14. 01-00~05=18(PID Function Disable)
When the PID Function Disable is ON, PID is not controlled by 09-00.
15. 01-00~05=19 (Integration Value Resets to Zero)
When the multifunction terminal 01-00~05 is set at 19 and the input terminal is on, the
Integration Value of PID Resets to Zero .
16. 01-00~05=20(Reset Command)
The Reset command is same as the Reset Key on the panel. When the command is OFF, the
inverter does not respond.
