1.2 Adjustment tools
1.2a Microswitches
The microswitches send a voltage signal when the desired speed request is made.
1.2b Potentiometer
In the 3-wire configuration, the CPOT (C1) useful input signal goes from 0V to 10V.
The resistive value of the potentiometer must be between 500 ohm and 10 kohm, as lower
values overload the power supply.
2-wire potentiometer (please request while ordering):
It is possible to use the potentiometer in the 2-wire configuration but you should state its
ohmic value since a resistor on the logic boars must be installed accordingly.
Correspondence between the voltage signal to pin C1 and motor voltage.
