IL (Integrator Limit)
[Tuning]
DESCRIPTION:
The IL command limits the effect of the integrator function in the filter to a certain voltage. For example, IL
2 limits the output of the integrator to the +/-2 Volt range. This is very effective in allowing higher
KI
(Integrator) values without adding instability.
A negative parameter also freezes the effect of the integrator during a move. For example, IL -3 limits the
integrator output to +/-3V. If, at the start of motion, the integrator output is 1.6 Volts, that level will be
maintained through the move. Note, however, that the
KD (Derivative Constant) and KP (Proportional
Constant) terms remain active in any case.
ARGUMENTS: IL x, y, z, w or ILX=x or IL a, b, c, d where
x, y z, w, or a, b, c, d are unsigned integers
USAGE:
OPERAND USAGE:
_ILn contains the value of the integrator limit in volts where n is an axis letter.
