B.2.16.22 Velocity Feedback Filters
The Velocity Feedback Filters panel allows the user to set the cut-off factor of this filter.
This is a low-pass filter included on the motor feedback velocity. It’s a simple Euler approximation filter
characterised by two filter coefficients (a
1
and b
0
).
VELOCITY FEEDBACK FILTER PARAMETERS :
• Cutoff → The cutoff frequency as a fraction of the velocity loop sample rate. Setting this factor to 0.5 sets the
filter cut-off to half the velocity loop sample rate.
B.2.16.23 Command Direction
The Command Direction panel allows the user to set the command polarity.
COMMAND DIRECTION PARAMETERS :
• Command Polarity → Allows the user to choose the command polarity to be either positive or negative.
