January 2012 6.18 Spindles 1027
Positioning the
spindle (M19/trip
dog position)
The PLC command defined in
Module 9414 instructs the NC to activate spindle positioning.
Module 9412 instructs the NC to deactivate spindle positioning.
Use Module 9414 to switch on position feedback control. Position feedback
control is effective until it is switched off by Module 9412.
Module 9414 Position the spindle
The module is used for the following functions:
Position the spindle (M19): The spindle is stopped at the specified position.
The mode defines the direction of rotation.
Stop the spindle at the trip dog position (mode bit 3 = 1): The spindle is
positioned to the trip dog at the specified rotational speed (see "Stopping/
referencing the spindle at trip dog position" on page 1005).
This module is only supported by the new symbolic memory interface. If the
iTNC-compatible interface (API 1.0) is used, the module returns an error.
Call:
PS B/W/D/K <>Spindle index>
PS B/W/D/K <>Mode>
Bits 0 to 2: Direction of rotation
000 = Shortest direction of rotation, absolute position
entry
001 = Rotation CW, absolute position entry
010 = Rotation CCW, absolute position entry
100 = Relative position entry, rotational direction from
algebraic sign of position entry
Bit 3: Select the function
0 = "Position the spindle (M19)" function
1 = "Stop spindle at trip dog position" function
PS D/K <>Absolute or relative position in [0.0001°]>
PS D/K <>Rotational speed in [0.0001 rpm]>
