Trapezoidal and square sine acceleration.

ACCEL
Acceleration.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): From 0.0000 to 600000000.0000 mm/s².
Possible values (2): From 0.00000 to 23622047.24409 inch/s².
Possible values (3): From 0.0000 to 600000000.0000 degrees/s².
Default value: 3000.0000 mm/s² / 118.12023 inch/s² / 3000 degrees/s².
Associated variable: (V.)[ch].MPA.ACCEL[set].xn
See machine parameter DECEL.
DECEL
Deceleration.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): From 0.0000 to 600000000.0000 mm/s².
Possible values (2): From 0.00000 to 23622047.24409 inch/s².
Possible values (3): From 0.0000 to 600000000.0000 degrees/s².
Default value: 3000.0000 mm/s² / 118.12023 inch/s² / 3000 degrees/s².
Associated variable: (V.)[ch].MPA.DECEL[set].xn
Parameters ACCEL and DECEL set the acceleration values when it is trapezoidal or square-
sine (bell shaped) (parameter SLOPETYPE). The CNC applies parameters ACCEL and
DECEL to the movements in G1, G2 and G3; movements in G0 depend on parameter
G0ACDCJERK.

1 The axis starts moving with a uniformly increasing acceleration, with a slope limited
by ACCJERK, until reaching the acceleration indicated in ACCEL.
2 The acceleration becomes constant at the ACCEL value.
3 Before reaching the programmed feedrate, there is a steady deceleration with a slope
limited by ACCJERK.
4 It goes on at the programmed feedrate and with no acceleration.
5 To slow down or stop the axis, a deceleration is applied with a slope limited by
DECJERK.
6 The deceleration becomes constant at the DECEL value.
7 Before reaching the programmed feedrate, or stopping, there is a deceleration limited
by DECJERK.
Meaning.
Movements in G0 use parameters ACCELG0 and DECELG0.
Movements in G0 use parameters ACCEL and DECEL.
