Value Description
0 Accelerates or decelerates at acceleration/deceleration time 1 or 2 presently selected.
1 Accelerates or decelerates at acceleration/deceleration time 2 set in n021 and n022.
• Select the acceleration/deceleration time with the stall prevention function operating function
enabled.
• To accelerate or decelerate quicker or slower than normal, set 1 in n116 and the acceleration time in
n021 (acceleration time 2) and deceleration time in n022 (deceleration time 2) for stall prevention use.
