Amplification current controller
If the armature circuit inductivity is high, all contacts of the switch S1 are
in ‘OFF’ position.
If the inductivity is low, all contacts are in ‘ON’ position.
The adjusted values can be exactly measured by displaying the motor
current on an oscilloscope.
Preset the command value step-change.
The first current half-wave must not exceed 1.5A.
(Adjustment by means of S1-3, S1-4).
The current should rise to 4A via 5 half-waves.
(Adjustment by means of S1-1, S1-2)
IxR compensation
(only for armature voltage control)
Adjust the speed to 10%.
Change the load between idle running and full load.
Compensate for the speed loss at full load by turning the potentiometer
IxR (P1) clockwise.
