Installation and Configuration Soloist CP
2.2.2.1. DC Brush Motor Phasing
A properly phased motor means that the positive motor lead should be connected to the ØA motor terminal
and the negative motor lead should be connected to the ØC motor terminal. To determine if the motor is
properly phased, connect a voltmeter to the motor leads of an un-powered motor:
1. Connect the positive lead of the voltmeter to the one of the motor terminals.
2. Connect the negative lead of the voltmeter to the other motor terminal.
3. Rotate the motor clockwise by hand.
Figure 2-16: Clockwise Motor Rotation
4. If the voltmeter indicates a negative value, swap the motor leads and rotate the motor (CW, by hand)
again. When the voltmeter indicates a positive value, the motor leads have been identified.
5. Connect the motor lead from the voltmeter to the ØA motor terminal on the Soloist CP. Connect the
motor lead from the negative lead of the voltmeter to the ØC motor terminal on the Soloist CP.
N O T E : If using standard Aerotech motors and cables, motor and encoder connection adjustments are
not required.
