Abbr. Inputs
PLC-VAL Value of this tool that is to be sent to the PLC.
Input range: -99999.9999 to +99999.9999
PTYP Tool type for evaluation in the pocket table.
Input range: 0 to +99
NMAX Limits the spindle speed for this tool. The programmed value is
monitored (error message) as well as an increase in the shaft
speed via the potentiometer. Function inactive: Enter –
Input range: 0 to +99999, if function not active: enter –
LIFTOFF Definition of whether the TNC should retract the tool in the
direction of the positive tool axis at an NC stop or power failure in
order to avoid leaving dwell marks on the contour. If Y is entered,
the TNC retracts the tool from the contour by up to 30 mm,
provided that this function was activated in the NC program with
M148 (see "Automatically retract tool from the contour at an NC
stop: M148" on page 341)
Input : Y and N
Machine-dependent function: Transfer of a value to the PLC.
P1 ... P3
Refer to your machine manual
Input range: -99999.9999 to +99999.9999
KINEMATIC Machine-dependent function: Kinematics description for vertical
milling heads, which the TNC adds to the active machine
kinematics. Assign available kinematic descriptions by using the
ASSIGN KINEMATICS soft key (see also "Tool-carrier
kinematics" on page 180)
Input range: 16 characters max.
T-ANGLE Point angle of the tool. Is used by the Centering cycle (Cycle 240)
in order to calculate the centering depth from the diameter entry
Input range: -180 to +180°
PITCH Thread pitch of the tool (currently without function)
Input range in mm: 0 to +99999.9999
Input range in inches: 0 to +3936.9999
Control setting for the adaptive feed control AFC that you have
AFC
defined in the NAME column of the AFC.TAB table. Apply the
feedback-control strategy with the ASSIGN AFC CONTROL
SETTING soft key (3rd soft-key row)
Input range: 10 characters max.
