General machine parameters
LOOPTIME (P72)
It sets the sample period used by the CNC and, consequently, affects the block processing time.
At the FL model, if general machine parameter LOOPTIME (P72) is set with a value lower than 4,
the period will be 4 ms.
IPOTIME (P73)
Not used
COMPTYPE (P74)
It determines how tool radius compensation is applied. This parameter has three digits.
(units) Type of tool radius compensation beginning and end.
The units set the type of beginning/end of tool radius compensation applied by the CNC.
(tens) Additional compensation block.
The tens indicate whether the additional compensation block is executed at the end of the current
block or at the beginning of the next block with compensation.
When the beginning or the end of the compensation takes place in a different plane (there is an
intermediate vertical movement) and with angle greater than 270º, one should be analyze the CNC's
behavior as shown next:
Value Meaning
0 4 ms period (standard).
1··6 Period in milliseconds.
Default value: 2 (Power model)
Default value: 0 (FL model)
Value Meaning
xx0 It approaches the starting point going around the corner.
xx1 It goes directly perpendicular to the point; without going around the corner.
Default value: 0
Value Meaning
x00 It is executed at the end of the current block.
x10 It is executed at the beginning of the next block with compensation.
Default value: 00
COMPTYPE = x0 COMPTYPE = x1
COMPTYPE = 00 COMPTYPE = 10
Executing block by block (single block
mode), the first movement ends at point
"B".
Executing block by block (single block
mode), the first movement ends at point
"A".
