G08
Acceleration for approach ramp and braking ramp
ć stepping motor axis; ć permitted in operating modes: Start/Stop, Record Select
Nn G08 X<Acceleration> [Y.., Z.., U..]
<Accelera-
tion>
n
Acceleration in %−steps of the configured maximum
acceleration; 0 = 100 %, 1 = 1 % ... 99 = 99 %
n = 0 ... 99
Rn
1)
Acceleration in %−steps of the configured maximum
acceleration saved in register Rn;
0 = 100 %, 1 = 1 % ... 99 = 99 %
n = 0 ... 99
@n
1)
Absolute value of the acceleration in [m/s
2
] or [10
3
°/s

]
saved in position register @n; permitted:
0.01
Ţ @n Ţ defined maximum acceleration
n = 0 ... 99
Effect
With the following command the stepping motor is moved and braked at maximum
with the acceleration specified here:
Ĉ G01
Example
N020 G08 X50 Y50
N021 G01 X80 FX50
N022 G08 X0
;Approach ramp and braking ramp = 50 %
;Move to position X80
;Approach ramp and braking ramp with
;maximum acceleration
The X−axis is accelerated and braked when approaching position X80 by only 50 %
of the configured maximum acceleration. The acceleration for the X−axis is then
switched to maximum acceleration.
Remark
This command has a saving effect. It remains effective until a new approach ramp
and braking ramp is defined.
