Acceleration

102
The run profile is defined by jerks, acceleration, and deceleration. Each jerk, accel
and decel holds three different values and is indexed through the offset number
(lead number in from of the parameter number). These different values make
up three different run profiles which are either assigned based on the selected
speed or through another parameter. The adjustment range for each is the same
although the default values vary.
When adjusting a profile, change the offset number first and then go to each
parameter. The profile number will not change when switching between
parameters making it easy to adjust one complete profile. Refer to section
4.3 for selecting the profile number.
In general higher values result in a hard/fast profile, while lower values give
softer, slower transitions.
Empirical values: 2.00...3.00 for retirement homes, hospitals,
3.00...5.00 for office buildings, banks etc.
When LF.2 is set to AbSPd, A SPd or A Tor, the values of all profiles are
When LF.2 is set d SPd or bnSPd the default values are loaded in all
Profile 2 is used for emergency operation as selected in parameter LF.61.

rated of acceleration or deceleration that the jerk must work with. Therefore the
minimum jerk value is limited by the actual adjusted value of the acceleration or
deceleration. If a lower jerk value is required, you must first reduce the rate of
acceleration or deceleration.
