4.8.2.4.2 Jerk limiting
The maximum acceleration change (jerk) is parameterized via the following ob-
jects. The resolution of the values is 1/100 s
-3
= 0.01 s

Maximum jerk at deceleration in FOR direction of rotation
(low speed)
0x2538
co56
rev acc jerk ls [s-3]
Maximum jerk at acceleration in REV direction of rotation
(low speed)
0x2539
co57
rev acc jerk hs [s-3]
Maximum jerk at acceleration in REV direction of rotation
(high speed)
0x253A
co58
rev dec jerk hs [s-3]
Maximum jerk at deceleration in REV direction of rotation
(high speed)
0x253B
co59
rev dec jerk ls [s-3]
Maximum jerk at deceleration in REV direction of rotation
(low speed)
Example:
The acceleration in the previous example should be reached after one second.
r = Δa/Δt
In our case with constant jerk it is:
r = a / t = 16.67s
-2
/ 1s = 16.67 s
