2.4.5 Time setting (channel).
PREPFREQ
Maximum number of blocks to prepare per cycle.
Possible values: From 1 to 8.
Default value: 1.
Associated variable: (V.)[ch].MPG.PREPFREQ
While executing a program, the CNC reads in advance the blocks to be executed in order
to calculate the path to follow; this is known as block preparations. The number of blocks
to be prepared depends on the type of machining operation; it is not the same to process
blocks generated with a CAD-CAM and the blocks coming from a program edited manually
or with canned cycles.
This parameter sets the maximum number of blocks the CNC must process in each cycle
(parameter LOOPTIME). The CNC will try processing the number of blocks set in this
parameter and, if not possible, it will only process the number of blocks that it can.
Besides preparing the blocks, the CNC carries out several tasks in each cycle. Increasing
the value of parameter PREPFREQ unnecessarily can jeopardize the rest of the task. Before
modifying the value of this parameter, check with the service department.
ANTIME
Anticipation time.
Possible values: From 0 to 10000000 ms.
Default value: 0.
Associated variable: (V.)[ch].MPG.ANTIME
This parameter is used on punch presses that have an eccentric cam as a punching system.
This parameter indicates how long before the axes reach position, the anticipation logic
signal ADVINPOS of the channel is activated .
This signal may be used to start the movement of the punch before the axes reach the
position. This reduces idle time, thus increasing the number of punches per minute.
If the total duration of the movement is lower than the value in the parameter, the anticipation
signal ADVINPOS will be activated immediately.
If set to zero, the anticipation signal ADVINPOS is always active.
