parameters for
path-specific limit
values
 In CfgLaPath, define the path-specific limit values for feed rate, acceleration
and jerk.
MP_minPathFeed allows you to define the minimum feed rate in an NC block.
The parameter is intended for technological purposes, in particular for
preventing dwell marks in small radii. If the values are too large, feed-rate
optimization becomes ineffective. This might lead to excessive dynamic load
on the machine.
MP_minPathFeed

Note
MP_minPathFeed is always limited to the programmed feed rate; this
means that look-ahead violates the defined minimum feed-rate value only
if a lower value is programmed in the NC block or is set by the override
potentiometer.
