Operation
pressing the mode switch key;
2) When the system executes the MPG trial-cut control, the single block signal and the feed
hold signal are valid. When the single block or feed hold stops, the program execution state
is recovered to the MPG trial-cut control after the cycle start key is pressed.
3) Execution speed of blocks for movement and pause can be controlled by rotating MPG.
Their speed of blocks with M, S, T, F, i.e. without movement or pause cannot be
controlled(except for executing the tool offset in traverse mode) by rotating MPG which only
controls whether they are executed.
4) The spindle speed is not related to the MPG pulse. The spindle rotates with the commanded
speed even if the system is in the MPG trial-cut mode. For feed per rotation, reading the
current spindle speed is switched to the execution after feed per minute.
9.3.4 Temporarily Invalid in MPG Trial-cut Mode
1) Executing screw cutting commands
In the course of executing screw cutting blocks (G32, G32.1, G33, G34, G76, G84, G88,
G92
，
G92.1), the MPG trial-cut function is temporarily invalid with the speed under the override
100%, and is valid in the next block again. The MPG control is invalid when the screw cutting is
executed actually, and it is valid in others.
2) Executing from the middle point to machine zero
In the course of executing the block (G28, G30) from the middle point to machine, the MPG
trial cutting function is enabled from the start to intermediate point, and the MPG trial cutting is
temporarily disabled from intermediate point to mechanical zero. The block is executed with the
speed under the override 100%, and the next block is valid again.
3) Measuring related G commands execution with the override 100%
When the system measures the related G commands, the MPG trial-cut is invalid
temporarily, is executed with the speed under the override 100%, at the moment, execution of
the next block is valid again. The related G commands include:
G31, G36, G37
9.4 MPG Interrupted Function
In the Auto (Auto, MDI) and Edit mode, In the Auto (Auto, MDI) and Edit mode, the movement
value from MPG can be overlapped to the Auto movement by rotating the MPG. The axis performed
the MPG interruption can be selected by the MPG interruption axis selection signal. The movement
distance of the MPG interruption is determined by the rotation value of the MPG and hand-wheel
federate.
Note
：
It is necessary to set the Bit 1 of parameter No.0012 to "1" when using the MPG interruption
function, it is necessary to support by dedicated PLC program.
9.4.1 MPG Interrupted Operation
In the Auto, MDI and Edit mode, enter to the MPG interruption state to perform the MPG based
upon the MPG axle number on the selection panel after controlling the [MPG interruption switch]
(External switch) once; retreat from the MPG interruption by pressing the [MPG interruption switch]
again.
