Examples of Gear Setting6.8 Speed Control Setting6.8.1 Smooth Acceleration/DecelerationFor smooth acceleration/deceleration during speed control, you can operate the motor bycreating acceleration/deceleration profile in trapezoidal and s-curve shapes. In addition, youcan perform s-curve operation by setting the speed command s-curve time to 1[ms] or more.The speed command acceleration/deceleration time (0x2301, 0x2302) is the time it takes toaccelerate to the rated speed or decelerate from the rated speed to full stop. (See the figurebelow)Figure 46. Speed ControlThe actual acceleration/deceleration time can be calculated as follows.Speed commandSpeed commandwww.comoso.com
