HEIDENHAIN TNC 430 PA/M - Direction of Spindle Rotation

6 – 186 HEIDENHAIN Technical Manual TNC 426, TNC 430
MP3412 Multiplication factor for MP3411.x
Input: 0.000 to 1.999
MP3412.0 with M05
MP3412.1 with spindle orientation
MP3412.2 for tapping with floating tap holder

7 In MP3140, enter the counting direction of the position encoder signals.
As soon as you set M4005 for M03, or M4006 for M04, the nominal speed
value is output. With M4007 for M05, the nominal speed value zero is output
(spindle stop).
M4005 to M4007 also controls the miscellaneous functions in the status
window. (See "Position and Status Display” on page 6 – 231).
If more than one marker is set at the same time, the error message
PLC: M4005, M4006, M4007 INCORRECT appears.
With M4014 you can reverse the direction of rotation, in order to adjust the
transmission for horizontal or vertical spindles, for example. The polarity of the
nominal spindle speed is inverted.
M4019 reverses the counting direction of the spindle.
