Special points to be noted
•
The accelerations are defined in the following machine data:
–
MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL
(acceleration in position control mode)
–
MD35200 $MA_GEAR_STEP_SPEEDCTRL_ACCEL
(Acceleration in the speed control mode)
•
The spindle override switch is active.
•
The positioning action (
SPOS
,
M19
and
SPOSA
) is canceled with each reset.
•
The positioning action is canceled with
NC STOP
.
•
The positioning velocity can also be programmed with
FA[Sn]
.
2.1.5
Axis mode
Why axis mode?
For certain machining tasks (e.g., on turning machines with end-face machining), the spindle
not only has to be rotated with
M3
,
M4
and
M5
and positioned with
SPOS
,
M19
and
SPOSA
, but
also addressed as an axis with its own identifier (e.g., C).
Prerequisites
•
The same spindle motor is used for spindle mode and axis mode.
•
The same position measurement system or separate position measurement systems can
be used for spindle mode and axis mode.
•
A position actual-value encoder is a mandatory requirement for axis mode.
•
If the axis is not synchronized, e.g.,
M70
is programmed after POWER ON, the axis must
first be homed with
G74
. Only then does the mechanical position match the programmed
one.
Example:
M70
G74 C1=0 Z100
G0 C180 X50
Configurable M function
The M function, which switches the spindle to axis mode, can be configured in machine data:
MD20094 $MC_SPIND_RIGID_TAPPING_M_NR.
The value on delivery is 70.
