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 for the approximate S-shaped acceleration/deceleration is longer by 64ms.
• Approximate S-shaped acceleration/deceleration
Specify 64ms or more (64 to 5000) for the acceleration time, acceleration time 2, deceleration time or
deceleration time 2.
• 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 performed 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

Description
Time needed to reach the maximum speed from zero speed
Time needed to reach zero speed from the maximum speed
Acceleration/deceleration time for interpolation operation.
Time to reach the operation speed from zero speed (for
acceleration) or time to reach zero speed from operation
speed (for deceleration)
Target position (absolute address) or travel distance (relative
address) in each operation mode
Target position (absolute address) or travel distance (relative
address) for two-speed positioning operation
The flag is reset at the beginning of each operation or at the
error occurrence, and it is set upon normal completion.
However, the flag is not set during stop operation or for the
following operations even if the operation finishes normally.
• JOG operation
• Mechanical zero return (data setting type)
• Manual pulse generator operation
• Variable speed operation
