CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Acceleration/Deceleration Operation with Short Movement
When the Command Speed is Higher than the Present Speed
When the Command Speed is Lower than the Present Speed
If the movement is short relative to the command speed, acceleration time or deceleration time
and you execute the axis start which cannot generate acceleration/deceleration curves
according to the command, perform the acceleration/deceleration operation as specified
below.
When positioning operation starts while the axis is stationary or the command speed becomes
higher than the present speed, the shorter the movement, the shorter the constant-speed
section becomes. In addition, when the movement becomes shorter, the acceleration /
deceleration operation is performed with the lowered reached speed while maintaining the
initial acceleration and deceleration speed (slopes).
When you change the command position by duplicate starts during direct operation or the
command speed becomes lower than the present speed, the shorter the movement, the
shorter the constant-speed section becomes. In addition, when the movement becomes
shorter, the deceleration operation is performed with the shorter deceleration time.
