PID Enable/Disable and PID Integral Reset
The PID enable/disable function disables the PID function temporarily through terminal input. This
overrides the A071 setting to control the motor frequency. Also, the PID integral reset function
clears the PID integral value that has until then been integrated through terminal input. This helps
stop the motor when the frequency control is shifted to the PID control.
For details on the PID function, refer to "PID Function" (page 4-20).
UP/DOWN Function
This function changes the Inverter output frequency using UP and DWN terminals of the multi-
function inputs.
•While the UP/DWN terminal is turned on, the acceleration/deceleration time depends on F002,
F003/F202, and F203.
•You can store a frequency set value after UP/DWN adjustment. Choose whether to store the value
with C101.
Also, you can clear the stored frequency set value by allocating 29 (UDC) to the desired multi-
function input and turning on/off the UDC terminal.
