6.17 Arc end-point tolerance

The control uses the NC-data which is entered to calculate the deviation in the arc radius between
the beginning and end of the arc. If the tolerance defined in MP7431 is exceeded, the error
message "Arc end-point in correct" will appear.
MP7431 Arc end-point tolerance
Entry: 0.0001 to 0.016 [mm]

6.18 Radius compensation R+, R-

A path to be traversed can be increased or decreased by the tool radius by entering "R+" or "R-".
The input dialogue is not initiated with the "L" key but directly with the orange axis direction key. For
reasons of compatibility this function has been retained for point and straight cut controls.
Example: X + 20 R+
G07
Paraxially corrected positioning blocks (R+/R-) and radius-corrected positioning blocks (RR/RL) must
not be entered one after another.
To avoid erroneous entries MP7246 can be used to disable the input of paraxial positioning blocks.
MP7246 Disable paraxial positioning blocks
Entry: 0 or 1
0 = paraxial positioning blocks enabled
1 = paraxial positioning blocks disabled

6.19 "POWER INTERRUPTED" Message

When the control voltage is disconnected the TNC issues the message "POWER INTERRUPTED".
The PLC is not active until this message is reset with the CE key.
The "POWER INTERRUPTED" message does not appear if MP7212 is set to 1.
MP7212 "POWER INTERRUPTED"
Entry: 0 or 1
0 = Reset "POWER INTERRUPTED" message with CE key
1 = No "POWER INTERRUPTED" message
