HEIDENHAIN TNC 430 PA/M - Speed Controller (Only TNC 426 PB;M, TNC 430 PA;M)

6 – 212 HEIDENHAIN Technical Manual TNC 426, TNC 430
6.12.11 Speed Controller (Only TNC 426 PB/M, TNC 430 PA/M)
A digital speed controller for the spindle is integrated in the TNC 426 PB/M and
TNC 430 PA/M:
7
77
7 With MP2501.x adjust the proportional factor, and with MP2511.x the
integral factor of the speed controller of the first spindle.
With Module 9164 you can read the actual speed value of the motor. (See "The
Control Loop” on page 6 – 109).
For the speed controller of the spindle, you can define the differential factor,
the low-pass filter, PT
2
second-order time-delay element, and the band-
rejection filter (See "Commissioning” on page 6 – 462).
