Deactivation (Cc_Fastoff) - Siemens sinumerik 840D sl Function Manual

Detailed description
2.3 Programming
Programming example
DEF REAL DIFFON= -0.08
DEF REAL DIFFOFF= 0.08
DEF REAL FEEDTOSWITCH= 20000
CC_FASTON( DIFFON, DIFFOFF, FEEDTOSWITCH )
Changing parameters
The parameters for the CC_FASTON( ) procedure can be modified at any time during the
execution of the part program. To do this, enter the procedure call again with the new
parameter values. The switching criterion (G0 edge change / velocity threshold value) may
also be changed.
Reset response
A reset (NC RESET or end of program) deactivates the function.
Boundary conditions
The following boundary condition must be observed:
Continuous-path mode
Although the CC_FASTON( ) procedure call must be programmed in a dedicated part
program block, this will not lead to a drop in velocity while continuous-path mode is active
(G64, G641,...).
2.3.2

Deactivation (CC_FASTOFF)

Syntax
CC_FASTOFF( )
CC_FASTOFF( ) is a procedure call and must therefore be programmed in a dedicated part
program block.
Functionality
The CC_FASTOFF( ) procedure call deactivates the function.
Boundary conditions
The following boundary condition must be observed:
Continuous-path mode
Although the CC_FASTON( ) procedure call must be programmed in a dedicated part
program block, this will not lead to a drop in velocity while continuous-path mode is active
(G64, G641,...).
