U211B2/ B3
Figure 23. Speed control, automatic retriggering, load switch-off, soft start
The switch-off level at maximum load shows in principle
the same speed dependency as the original version (see
figure 2), but when reaching the maximum load, the
motor is switched off completely.
This function is effected by the thyristor (formed by T1
and T2) which ignites when the voltage at Pin 15 reaches
typ. 7.4 V (Reference point Pin 16). The circuit is thereby
switched into the âstand-byâ over the release Pin 18.
