TDA7272A
In order to compensate the behaviour of the
whole system regulator-motor-load (considering
axis friction, load torque, inertias moment of the
motor of the load. etc.) a RC series network is
also connected between pins 13 and 14 (fig. 12).
The value of CA and RA must been chosen ex-
perimentally as follows:
- Increase of 10 % the speed with respect to
the nominal value by connecting in parallel
to Rp a resistor with value about 10 time
larger.
- Vary the RA and CA values in order to ob-
tain at pin 13 a voltage signal with short re-
sponse time and without oscillations. Fig.
13 shows the step response at pin 13 ver-
sus RA and CA values.
Pin 14
