Programming

Channel-specific activation (DRIVE)
Syntax
DRIVE
Functionality
The knee-shaped characteristic curve is activated for path acceleration using the DRIVE part-
program instruction.
G group: 21
Effective: Modal
Reset response
The channel-specific default setting is activated via a reset:
MD20150 $MC_GCODE_RESET_VALUES[20]
Dependencies
If the knee-shaped acceleration characteristic curve is parameterized for a machine axis, then
this becomes the default acceleration profile for all traversing operations.
If the effective acceleration profile is changed for a specific path section using the SOFT or
BRISK part-program instructions, then an appropriate substitute characteristic curve with lower
dynamic limit values is used in place of the knee-shaped acceleration characteristic curve.
The knee-shaped acceleration characteristic curve can be reactivated by reprogramming
DRIVE.
Axis-specific activation (DRIVEA)
Syntax
DRIVEA (
Functionality
The knee-shaped characteristic curve is activated for all single-axis interpolations (positioning
axis, reciprocating axis, etc.) for specific axes using the part-program command.
