General
1.3 Programming cycles
No plausibility checks are made of parameter values
with a discrete or limited value range unless an error
response has been specifically described for a cycle.
If the parameter list contains more entries than defined
as parameters in the cycle when the cycle is called, the
general NC alarm 12340 "Too many parameters" is
generated. The cycle is not executed in this case.
Cycle call
The various methods for writing a cycle call are shown
in the following example, CYCLE100, which requires the
following input parameters.
Example
Definition of the machined shape
FORM
Values: E and F
Infeed depth (to be entered without a sign)
MID
Feedrate
FFR
Machining type
VARI
Values: 0, 1 or 2
Final machining allowance
FAL
The cycle is called with command
CYCLE100 (FORM, MID, FFR, VARI, FAL).
1. Parameter list with constant values
Rather than input individual parameters, you can
directly enter the concrete values to be used in the
cycle.
Example
CYCLE100 ("E", 5, 0.1, 1, 0)
2. Parameter list with variables as transfer
parameters
You can transfer the parameters as arithmetic
variables that you define and assign values before
you call the cycle.
