Free Rotation - HEIDENHAIN TNC 426 PB/M Technical Manual

Free rotation

Free rotation
defined by words
Free rotation with
Module 9223
6 – 234
Free rotation means that the rotary axis rotates as often as required (with a
display range of 0 to 360°) without being affected by software limit switches.
You can define the free rotation function through words (axis 4 and 5) or with
Module 9223 (axis 1 to 9).
The maximum feed rate is 300 000 °/min. The feed rate is not shown in the
status window. You can change the feed rate with the override potentiometer
(W754), for example by copying W494 (active feed rate override) to W754.
MP7620 bit 3 is accounted for.

M4133 Starting and stopping the free rotation function
If you set M4133, the NC takes the information from B518 and B519 and
resets M4133.
If a program has been started, the module may be called only in conjunction
with an M/S/T/Q strobe.
Module 9223 Free rotation
When the module is called, M4133 is set (start and stop).
The feed-rate override in W754 remains in effect.
