Description
AXIS#.PL.KI sets the integral gain of the position regulator PI loop. It is only active when AXIS#.OPMODE = 2 (Position).
The user can also configure when the position integrator is disabled. By setting AXIS#.PL.KITHRESH, whenever the velocity trajectory exceeds AXIS#.PL.KITHRESH, the position integrator will turn off.
Integrator Dependencies
- By default, the drive is configured to only allow one integrator to be active at a time (See AXIS#.VL.KIMODE for details).
- The position integrator takes precedence
In arithmetic and algebra, when a number or expression is both preceded and followed by a binary operation, a rule is required for which operation should be applied first. From the earliest use of mathematical notation, multiplication took precedence over addition, whichever side of a number it appeared on. Thus 3 + 4 × 5 = 5 × 4 + 3 = 23.
To change the order of operations, we use parentheses (). Thus, if we want to force addition to precede multiplication, we write (3 + 4) × 5 = 35 over the velocity integrator. If AXIS#.PL.KI is being used, AXIS#.VL.KI
will be disabled.
To use both integrators together, use AXIS#.PL.KITHRESH to set the point at which the integrators toggle, or set AXIS#.VL.KIMODE to allow all integrators to be active at the same time.
- If AXIS#.IL.CMD saturates and is clamped by AXIS#.IL.LIMITP or AXIS#.IL.LIMITN , then the integrator will hold and stop integrating. The integrator will keep its current state and continue to wind up or discharge once the axis comes out of current saturation
