Phase 1
Case 1: Spindle not synchronized
The programming of
SPOS
,
M19
or
SPOSA
accelerates the spindle with the acceleration from
machine data:
MD35200 $MA_GEAR_STEP_POSCTRL_ACCEL (Acceleration in positioning mode).
The direction of rotation is defined in machine data:
MD35350 $MA_SPIND_POSITIONING_DIR (Direction of rotation when positioning from
standstill)
.
Exception:
If
ACN
,
ACP
,
IC
is used for positioning, the programmed direction of travel is activated.
The spindle is synchronized with the next zero mark of the spindle-position actual value
sensor and goes into position control mode.
It will be monitored whether the zero mark is found at the distance stored in the machine
data:
MD34060 $MA_REFP_MAX_MARKER_DIST
(except for IC).
If the speed defined in machine data:
MD35300 $MA_SPIND_POSCTRL_VELO (Positioning speed)
is reached before the spindle is synchronized, the spindle will continue to rotate at the
positioning creep speed (the spindle is not accelerated further).
Case 2: Spindle synchronized
SPOS
,
M19
or
SPOSA
will switch the spindle to position control mode.
The acceleration from the following machine data is active:
MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL (acceleration in the position control mode)
.
Rotational direction is determined through the programmed movement (
ACP
,
ACN
,
IC
,
DC
) or
through the queued remaining distance.
The speed given in the machine data:
MD35300 $MA_SPIND_POSCTRL_VELO (position control activation speed)
is not exceeded.
The travel path to the end point is calculated.
The spindle travels to the programmed end point optimally in terms of time.
This means that the end point is approached at the highest possible speed
(maximum MD35300 $MA_SPIND_POSCTRL_VELO).
Depending on the appropriate secondary conditions, the operational sequences in phases 1
- 2 - 3 -4,
or 1 - 3a - 4a are executed.
