Monitoring The Speed Controller - HEIDENHAIN TNC 415 Technical Manual

If the motor and drive spindle are linked by a toothed belt then an initial overshoot will occur in the
step response – this must be disregarded for trimming purposes.

Monitoring the speed controller

Once the proportional and integral components of the speed controller have been trimmed, a
suitable value must be calculated for MP1910.x.
Example: MP1920.x = 180
For MP1910.x with a Vlimit = 15 V, the following value is obtained:
MP1910.x =
11-14 TNC 407/TNC 415/TNC 425
MP1940.x = 60
Vlimit
= 9000
MP1920.x * 9.7 µV
