Tangential Control (T3)
22.3 Use of "Tangential control" function
22.3.4

Response at corners, activation "with intermediate block": TLIFT

Programming
Following the definition with TANG( ), the TLIFT instruction with the following axis must be
written if the corner response "with intermediate block" is required.
TLIFT (C)
The control considers the associated machine data MD37400 EPS_TLIFT_TANG_STEP for
the tangential following rotary axis C. If the tangential angle jump exceeds the angle
(absolute value) of the angle set in the MD, the control recognizes a "corner" and
approaches the new position of the follow-up axis via an inserted intermediate block.
22.3.5

Switching off the axis coupling: TANGOF

Programming
The axis coupling is switched off using the predefined subroutine TANGOF( ). The following
axis is hereby specified. This specification refers to the definition of leading and following
axes made beforehand with TANG. With reference to the above example, the termination is:
TANGOF(C)
The follow-up control process initiated with TANGON is terminated. Termination of follow-up
control initiates a preprocessing stop (preprocessor stop).
Information
The master (leading) axes and following axis, defined using TANG( ... ) are not cleared by
TANGOF.
After RESET/part program end, no tangential control is active (default setting).
22.3.6

Deactivation of corner response "with intermediate block"

Programming
In order to stop generating the intermediate block at corners with active tangential follow-up
control, the definition block TANG(...) must be repeated without a following TLIFT( ).
