8025/8030 CNC PROGRAMMING MANUAL 127
Example:
To program K=1/3, if M45 K0.3333 is programmed, a lesser accuracy will be obtained
than if the following is programmed:
N - P1=K1 F4 K3
N - M45 KP1
If the rpm’s are greater than the limit established by machine- parameter P802, the CNC
will display error 17. Also, when the following error of the synchronized tool is too large,
the CNC will display error 71.
Nothing else can be programmed in the block whether is format a) or b).
To stop the rotation of the live tool in either case M45 S0 or only M45 must be
programmed.
c) Machine parameters associated with the synchronized or live tool.
Parameters to be borne in mind as as follows:
P802 indicates the maximum number of rpm of the synchronized tool(when exceeded,
the CNC produces error 17). Its maximum number is 9999.
P803 indicates the number of impulses/encoder rotation of the live tool.
P609 bit 8 indicates whether we can vary the speed of the live tool by means of the
SPEED RATE (between 50% and 120%).
P711 defines the gain of the synchronized tool. (acceleration/ deceleration).
P607 bit 2 indicates the counting direction of the synchronized tool.
P607 bit 1 indicates the analog sign of 1 to the synchronized tool.
Atention:
If these last two parameters are not well coordinated the CNC immediately
produces the following error as soon as the synchronized tool begins to
move.
