4. When circular interpolation has been specified, an error is generated if cutter compensation is started or canceled. When positioning
(G00) or linear interpolation (G01) has been specified, cutter compensation should be started or canceled.
5. When cutter compensation for circular interpolation is performed, parameters cannot be changed using the display with operation
paused.
6. When fixed-cycle operation has been specified, executing or canceling cutter compensation causes an error to be generated.
7. Performing any of the following operations or settings during cutter compensation causes an error to be generated.
Changing the offset number
Switching the direction of compensation : When G41 (cutter compensation -- left) has been used, executing G42 causes an error to
Specifying a plane
Scaling
Fixed cycle
Specifying a coordinate system
Calling a subprogram or returning to the main program : Executing M98 or M99 causes an error to be generated.

Setting the Amount of Offset
The PNC-3200 allows amounts of offset to be set individually for offset numbers 1 to 10. An amount of offset can be set using either of
two methods.
1. Using the display on the PNC-3200
The PNC-3200's LCD screen and control keys are used to set the amount of offset. See the "User's Manual 3 Cutting Using NC-
Codes" for a description of the procedure.
2. Using code (G10)

Note: The ranges shown above are the ranges where the amount of offset for cutter compensation can be used.
* If G41 or G42 is used to specify an offset number for which no amount of offset has been set with G10, the value that has been set on
the PNC-3200 is used.
* Setting a negative value for an amount of offset causes the offset direction of G41 and G42 to be reversed as shown below.
G00G41D01X100.0
G00G42D01X100.0
* An amount of offset of zero is set for offset number 0. The amount of offset for offset number 0 cannot be changed.
: To change the offset number, first cancel cutter compensation. Then execute G41 or G42
again, and change the offset number.
be generated. Similarly, when G42 (cutter compensation -- right) has been used, executing
G41 causes an error to be generated.
: Executing G17, G18, or G19 causes an error to be generated.
: Executing G50 or G51 causes an error to be generated.
: Executing G80, G81, G82, G85, G86, or G89 causes an error to be generated.
: Executing G10, G54 to G59, or G92 causes an error to be generated.
: Executing M06 causes an error to be generated.
