Preliminary Information
Applications
In contrast to simple speed controller”, the circuits shown in Figures 15 and 16, react to the load dependent speed drop
in which the magnitude of the load current acts on the speed compensation.
For this purpose, the load current is measured by shunt resistor R
8
. The voltage drop generates a current at Pin 11
dependent of R
5
, which reflects in the specified current at the output of Pin 12.
Rated impedance of the output current at Pin 12 is represented through the coupling resistance R
7
and the total impedance
of the set point.
The integrated load current proportional signal at C
3
effects in the same direction on the control input as the set point i.e.,
by the increase of load current follows an automatic increase of manipulated set point, so that a compensation of speed
falls.
Compensation arrangement is influenced with resistance values i.e. R
5
(= 100 ... 5 k ) and R
7
(= 10 k
whereas the higher effect is achieved by increasing the value of R
7
and decreasing R
5
. Influence of compensation can be
increased up to the value where the drive system (motor) starts to oscillate.
... 150 k )
Dimensioning in the applications are with the drill machine of 700 W power.
