2.17.2 Activation
2.17.2.1 Parameterization
Activation
The jerk filter is activated using the machine data:
MD32400 $MA_AX_JERK_ENABLE = TRUE
The jerk filter is active in all operating modes and with all types of interpolation.
Filter mode
The mode is selected using the machine data:
MD32402 $MA_AX_JERK_MODE =
mode
Mode = 1 (2nd-order filter)
Mode = 2 (Sliding mean value generation)
Mode = 3 (Bandstop filter)
2.17.3 Programming
Key statement
The function is not programmable.

2.18.1 Detailed description
2.18.1.1 Adaptation for the motor characteristic curve
Key statement
Various types of motor, particularly stepper motors, have a torque characteristic that is highly
dependent upon speed and shows a steep decrease in torque in the upper speed range. To
ensure optimum utilization of the motor characteristic curve, it is necessary to reduce the
acceleration once a certain speed is reached.
