The following describes the method of adjusting the power supply voltage on Servo1 and Quad Drives This
procedure describes how to adjust the 5 volts on the power supply and how to check the other voltages on this
power supply
This procedure should be done with the power supply under load i e still connected to the drive
1 Measure the voltage between V1 and G2 of the power supply See figure 1
2 Turn the voltage adjustment pot until the voltage is around 5 1 volts
3 Measure between pins V2 and G2 and pins V3 and G2 to make sure they are within the specs listed in table
1 Note These voltages are NOT adjustable
4 Replace the power supply if any of the voltages are out of spec
