VL.KIMODE

Description

This parameter sets whether the velocity mode is:

0 – Always on

1 – On ONLY if the position loop integrator is inactive.

PL.KITHRESH can be used to set a velocity command threshold to control at what part of a move the position loop integrator is active. When the position loop integrator becomes inactive, the velocity loop integrator will become active.

Common Uses

As a general rule, PL.KI should not be used at the same time as VL.KI , the two integrators will oppose each other and likely cause undesirable results, sometimes a runaway. Using PL.KITHRESH in conjunction with VL.KIMODE the user can specify operating conditions to switch between integrators based on machine operation.

Often times it makes sense to use the velocity integrator during a move, but as the motion comes to an end, to switch back to the position integrator for fine positioning.
