Activating and deactivating clearance control (CLC)

Syntax
CLC(
Mode
• Format: Integer
• Range of values: -1, 0, 1, 2, 3
CLC(...) is a procedure call and must therefore be programmed in a dedicated part program
block.
Functionality
The following modes are available for activating/ deactivating clearance control:
• CLC(1)
Activation of the clearance control with compensation vector in the direction of the tool
orientation
The evaluation of the sensor collision signal is deactivated.
• CLC(2)
Activation of the clearance control with compensation vector in the direction of the tool
orientation
The evaluation of the sensor collision signal is activated.
• CLC(3)
Activation of the clearance control with programmed compensation vector
The evaluation of the sensor collision signal is deactivated.
• CLC(0)
Deactivation of clearance control without canceling the position offset.
If the clearance-controlled axes are still moving at the instant of deactivation due to the
sensor signal, they are stopped. The workpiece coordinate system (WCS) is then
synchronized with the corresponding standstill positions. An automatic preprocessing stop
is executed.
• CLC(-1)
Deactivation of clearance control with cancellation of the position offset
If the clearance-controlled axes are still moving at the instant of deactivation due to the
sensor signal, they are stopped. A position offset to the last programmed position is
canceled automatically with the deactivation command.
