Note
• Trapezoidal acceleration/deceleration and approximate S-shaped acceleration/deceleration
If trapezoidal acceleration/deceleration and approximate S-shaped acceleration/deceleration are
performed under the same conditions (travel distance, operation speed and acceleration/deceleration
time), the positioning time of approximate S-shaped acceleration/deceleration becomes longer by 64ms.
• Approximate S-shaped acceleration/deceleration
Specify 64ms or larger (64 to 5000) acceleration and deceleration time.
• If the operation speed [jog speed, operation speed 1, operation speed 2, zero return speed (high speed) or
zero return speed (creep)] is 0Hz, operation is at 1Hz.
• When the operation speed is changed by the override function during interpolation operation, the
acceleration/deceleration time (interpolation time constant) changes according to the ratio by which the
operation speed changes
