Reference mark for spindle not yet

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.

B/W/D/K <Angle [1/10 000 °]>

or additional preset if there is a value from CYCL DEF 13

B/W/D/K <Speed [1/1000 rpm]>

0: MP3520.1 is assumed

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

Error recognition:

Spindle is brought to an oriented stop

Error code in W1022

Incorrect value for direction of rotation or rotational

Incorrect speed

No feedback-controlled spindle
