WebAfter all of the connections are made, the following code can be uploaded to the Arduino to control the speed of the motor: // Include the servo library #include // Create a servo instance Servo servo1; void setup () { servo1.attach (9); // Set the servo to its zero position and wait one second. WebSep 23, 2008 · Its control scheme uses one contactor for one speed and both contactors for the other speed. In your case it is probably a variable torque motor so the normal scheme is: low speed is the first contactor and high speed is both. Motors are the same. Identical towers. 3 phase 480 volt.
