BECKHOFF AX5000 S-IDN Parameters - Manual (Page 112)

S­IDNs
S­x­0137 Negative acceleration limit value
The parameter limits the maximum drive delay (negative acceleration) to the specified value. The
acceleration is negative if the magnitude of the velocity decreases.

This parameter influences the axis control in all position­ and velocity­controlled operating modes. The
dynamics of the control­side set value specification should be lower than the limit configured here, because
otherwise the axis cannot follow the specified acceleration, resulting in discrepancies between the set and
actual positions (following error).
Note
Parameter set switchover is possible!
This IDN exists as S­0­0137; S­1­0137; S­2­0137; S­3­0137; S­4­0137; S­5­0137; S­6­0137
and S­7­0137. Ex factory, all values are identical.
