Programming; Activation (Cc_Faston) - Siemens sinumerik 840D sl Function Manual

Effect on other output signals
The hardware-timer-controlled output of the switching signal at the parameterized output
delays the signal output for the other digital on-board outputs, e.g. due to synchronized
actions, by 2 IPO cycles.
Note
The output of the switching signal delays the signal output of the other digital on-board
outputs by 2 IPO cycles.

Activation (CC_FASTON)

Syntax
CC_FASTON( <
CC_FASTON( ) is a procedure call and must therefore be programmed in a dedicated part
program block.
Functionality
The parameters for the CC_FASTON( ) procedure have the following meaning:
• Parameter 1
• Parameter 2
• Parameter 3
Special functions: Cycle-Independent Path-Synchronous Signal Output (TE8)
Function Manual, 11/2006, 6FC5397-2BP10-2BA0
Parameter 1
Length of the offset distance for activation of the switching signal. The parameter unit
corresponds to the specified setting via the following machine data:
MD10240 $MN_SCALING_SYSTEM_IS_METRIC (basic system metric)
Length of the offset distance for deactivation of the switching signal. The parameter unit
corresponds to the specified setting via the following machine data:
MD10240 $MN_SCALING_SYSTEM_IS_METRIC
This parameter is optional.
If the parameter is not specified in the procedure call, the G0 edge change is used as the
switching criterion.
If the parameter is specified in the procedure call, it contains as a switching criterion the
velocity threshold value, which, when undershot or exceeded, activates or deactivates the
switching signal accordingly.
