Short Description Current Limit for velocity-dependent friction compensation

Description

The two parameters ISTFR and VSTFR define the friction compensation curve. If ISTFR is set to 0 the function is inactive. The friction compensation changes the additional current from -ISTFR to ISTFR if the velocity changes from -VSTFR to VSTFR. The current is added before the velocity filter, so the filter applies also to the friction compensation.

It is a configuration parameter if it is changed from "0" to another value, other changes can be done online.

V=0 -> IFRICT = 0
V= 50% of VSTFR -> IFRICT = 50% of ISTFR
V>=VSTFR -> IFRICT = ISTFR
V= -50% of VSTFR -> IFRICT = -50% of ISTFR
V<=-VSTFR -> IFRICT = -ISTFR
