VLIM
Definition User Velocity Limit
Type Variable (R/W)
Description Gets/sets the application velocity limit, allowing the user to
limit the motor’s peak velocity.
VLIM limits the velocity command that will be accepted from
the user (using the J command in OPMODE 0) or issued by
the control loops (in OPMODE 1). VLIM is an independent
variable that is not calculated from hardware parameters and
is not tied to any other variables. VLIM is similar to ILIM
(used in OPMODE 2 and OPMODE 3) and can be used to
protect delicate load equipment.
When the value of VLIM is changed, CONFIG is required.
