Descriptions
This is output of the internal regulated supply voltage. Make
connections from this pin to pot-entiometer and pulse
stretcher resister.
Connect the capacitor and resistor of the pulse stretcher
section.
Connect the capacitor and band can be changed according
the value of this capacitor.
Connect a capacitor that will determine the constant current
value of pin 6. Constant current will became 100 µA at the
time of the resistance of 18 k
Connect a capacitor that will adjust a triangular wave
made by charging of constant current.
Connect to the potentiometer for the position detection
connected with the output axis.
Grounding
Connect to the base of the external NPN transistor
Connect to the base of the external PNP transistor
Connect to the base of the external NPN transistor
Connect to the base of the external PNP transistor
Connect a capacitor of more than 10 µF.
Connect a capacitor that will determine the fixed
driving pulse width.
