V1101, 3.32

Parameter 32:

Closing ramp offset

Range

: -9.99 -+ 9.99

Default

: 2.50

Units

:

mm

Function

Offset to adjust beam at mute position.

Description

When the beam approaches the mute point it starts braking. The braking ramp is computed by
the control. With the parameter "closing ramp offset" the start of the braking ramp can be set
relative to the mute position.
