6. APPLICATION FUNCTIONS
When the acceleration time constant is changed during the acceleration, acceleration based on the Sin-curve
is performed again from the time of the completion of acceleration time constant change preparation.

When deceleration to a stop is performed with rapid stop time constants such as rapid stop (RSTP) and
interlock (ITL), the S-curve acceleration/deceleration is canceled and linear deceleration is performed. When
deceleration to a stop is performed with deceleration time constants such as operation alarms, the S-curve
acceleration/deceleration is performed.
