December 2001 Spindle 6 – 203
With Module 9171 you can specify the speed, nominal position and direction
of rotation for spindle orientation.
M4130 is set as long the positioning movement lasts.
The module functions only in the cyclic PLC program. If you call the module
while the spindle is rotating, the transferred direction will be ignored. The
spindle will be oriented in the direction of spindle rotation.
If the values 2 to 4 are transferred as direction of rotation, the spindle will be
oriented to the angle last defined in CYCL DEF 13. The transferred angle is
added to the value from CYCL DEF 13.
Module 9171 Oriented spindle stop
Can only be called from the sequential program.
Call:
PS
B/W/D/K <Angle [1/10 000 °]>
or additional preset if there is a value from CYCL DEF 13
PS B/W/D/K <Speed [1/1000 rpm]>
0: MP3520.1 is assumed
PS B/W/D/K <Direction of rotation>
–1: Negative direction (M04)
0: Direction of the shortest path
1: Positive direction (M03)
2: Same as –1 but angle from CYCL DEF 13
3: Same as 0 but angle from CYCL DEF 13
4: Same as +1 but angle from CYCL DEF 13
