Required settings
•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.
