848 HEIDENHAIN Technical Manual iTNC 530 HSCI
6.8.4 Speed controller
Up to 20 digital speed controllers for the axes and spindle(s) are possible in the
iTNC 530 HSCI:
The actual speed values are measured directly at the motors with
HEIDENHAIN rotary encoders. The position controller provides the nominal
speed value. The speed controller is driven by the difference between nominal
and actual speed values. It provides the nominal current value as output.
“Commissioning" on page 1004.
With Module 9164 you can read the actual speed value of the motors.
You can adjust the step response of the speed controller:
With the position controller switched off, enter with MP2500.x a
proportional factor and with MP2510.x an integral factor for the speed
controller. Adjust the step response so that only one overshoot is visible and
the settling time t
off
is as small as possible.
Realistic values for the settling time: 3 ms to 15 ms.
MP2500.x Proportional factor of the speed controller
Input: 0 to 1 000 000.000 [As]
MP2510.x Integral factor of the speed controller
Input: 0 to 100 000 000 [A]
