DD5 also controls the PC on function to reduce motor rotation overshoot when MD9 is 1
(discriminator control). This function does not operate when D9 is 0. The precharge voltage (i.e.,
the integrator output voltage initial clamp voltage) can be set by Vp1 to Vp3 (DD6 to DD8). The
figure shows the precharge operation.
