Filtering the Jerk
The Actual Jerk is filtered by default. See the Actual Jerk Filter
topic for details on filtering
the Actual Jerk. Filtering makes the Actual Jerk less noisy.
Algorithm Usage
The Actual Jerk is used in both Active Damping and Acceleration Control. The following
gains apply to the Actual Acceleration:
• Triple Differential Gain
• Active Damping Differential Gain

Description
The Actual Pressure or Actual Force is the measured pressure or force of the axis at any
moment. This value is updated every control loop.
The pressure or force is calculated as follows:
Pressure Input:
Voltage Input:
Actual Pressure = Voltage * Pressure Scale + Pressure Offset
Current Input:
Actual Pressure = Current * Pressure Scale + Pressure Offset
Single-Input Force:
Voltage Input:
Actual Force = Voltage * Force Scale + Force Offset
Current Input:
Actual Force = Current * Force Scale + Force Offset
Dual-Input (Differential) Force:
Actual Force = Channel A Force - Channel B Force
The Actual Pressure or Force may be filtered. See the Actual Pressure/Force Filter
for
details.
