* 1. Hold the operation signal to continue operation after recovery from a
momentary power loss.
* 2. When 2 is selected, the Inverter restarts if power supply voltage recovers
while the control power supply is held.
No fault signal is output.
* 3. Do not select 3 to 100 as they are reserved for future use.
S-curve Selection (n023)
To prevent shock when starting and stopping the machine, acceleration/
deceleration can be performed using an S-curve pattern.
Note: The S-curve characteristic time is the time from acceleration/decelera-
tion rate 0 to the normal acceleration/deceleration rate determined by the
set acceleration/deceleration time.
The following time chart shows switching between FWD/REV run
when decelerating to a stop.
