4.3 Spindle control
The spindle may be controlled manually using the following keys of the operator
panel. The keys always refer to the master spindle of the active channel.
The spindle speed should be set (in the MDI mode) before selecting the turning
direction, thus avoiding a sudden start of the spindle when setting an "S" because
the turning direction was active.
Starts the spindle clockwise. Same as function M03.
Start the spindle counteclockwise. Same as function M04.
To stop the spindle. Same as function M05.
Spindle speed override.
Spindle orientation. Same as function M19.
Customizing the keys
The machine manufacturer sets the minimum and maximum percentages between
which the speed may be varied as well as the percentage of variation every time one
of these keys is pressed.
They are set using the following machine parameters.
MINOVR Minimum override.
MAXOVR Maximum override.
STEPOVR Override increment (step).
Starts the spindle clockwise at the active speed.
Displays function M03 in the history of the current machining conditions.
Starts the spindle counterclockwise at the active speed.
Displays function M04 in the history of the current machining conditions.
To stop the spindle.
Displays function M05 in the history of the current machining conditions.
It may be used to vary the spindle turning speed, a typical value being a variation
between 50% and 120%. Every time one of these keys is pressed, the speed varies
5%.
These values may be different depending on how the machine manufacturer has
defined them.
It orients the spindle.
Displays function M19 in the history of the current machining conditions.
