VL.LIMITN
General Information
Type NV Parameter
Description
Sets the velocity lower limit; active in opmodes 1 (velocity) and 2 (posi-
tion) only.
Units
Depends on UNIT.VROTARY or UNIT.VLINEAR
Rotary: rpm, rps, deg/s, (PIN/POUT)/s, rad/s
Linear: counts/s, mm/s, µm/s, (PIN/POUT)/s

Description
VL.LIMITN sets the velocity command negative limit.
If the input to the velocity loop is lower than VL.LIMITN, then the actual velocity command VL.CMD is limited by
the value of VL.LIMITN.
