Functions
2.18 Kneeshaped acceleration characteristic curve
Basic logic functions: Acceleration (B2)
50 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
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.
2.18.3.2 Axis-specific activation (DRIVEA)
Syntax
DRIVEA (
Axis
{
Axis
})
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 instruction.
G group: -
Effective: modal
Axis
:
• Value range: Axis identifier for channel axes
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 axis using the SOFTA or BRISKA
part-program instructions, then an appropriate substitute characteristic curve is used in place
of the knee-shaped acceleration characteristic curve.
It is possible to switch back to the knee-shaped acceleration characteristic curve for a
specific axis by programming DRIVEA.
