Potentiometers/Tuning
The C1 has 4 potentiometers (RP1, RP2, RP3 and RP4) which
allow the user to adjust different gains depending on jumper
configuration. For instructions on how to switch between
configurations see the Jumper Configurations section. A
polymer non-conductive screwdriver is the preferred method
for adjusting the potentiometers. Care should be taken not to
allow metal screwdrivers to touch other components on the
board.
Proportional Gain –By adjusting the proportional gain,
the user can adjust the responsiveness of the system
to changes in command or feedback. The
responsiveness of the system can be increased or
decreased by turning the proportional gain clockwise
or counterclockwise, respectively. A gain that is too
low can result in an unresponsive system while a gain
that is too high can cause the system to become
unstable.
Derivative Gain – By adjusting the derivative gain, the
user can set the damping applied to the system. This
damping can be increased or decreased by turning
derivative gain clockwise or counterclockwise,
respectively. Damping helps reduce overshoot and
smoothes out system performance. However, too
much derivative can cause the system to undershoot
and “creep” into the target position or become
unstable.
Integral Gain – By adjusting the integral gain, the user
can reduce the steady state error of the system.
Integral gain be increased or decreased by turning the
potentiometer clockwise or counterclockwise,
respectively. Too little integral gain can result in
steady state error while too much integral gain can
cause oscillations and overshoot.
Ramp Rate – By adjusting the ramp rate, the user can
set the ramp rate of the command input to the
controller. The ramp rate be increased or decreased
by turning the potentiometer clockwise or
counterclockwise, respectively. A high ramp rate
results in a slower rise time while a lower ramp rate
results in a faster rise time.
Minimum Feedback –By adjusting minimum feedback,
the user can offset the minimum feedback value for
the controller. For feedback sensor with a minimum
output greater than 0V or 4mA, this adjustment should
be used. The minimum feedback be increased or
decreased by turning the potentiometer clockwise or
counterclockwise, respectively. For sensors that do not
require any offset, this potentiometer should be set
fully counter clockwise.
Maximum Feedback –By adjusting maximum feedback,
the user can offset the maximum feedback value for
the controller. For feedback sensor with a maximum
output less than 10V or 20mA, this adjustment should
be used. The maximum feedback be increased or
decreased by turning the potentiometer clockwise or
counterclockwise, respectively. For sensors that do not
require any offset, this potentiometer should be set
fully clockwise.
