9. Set the IR COMP trimpot full CCW.
10. Set the TACH VOLTS trimpot full CW.
11. Set the speed adjust potentiometer or input signal to
maximum speed.
12. Adjust the TACH VOLTS trimpot until the armature voltage is the same value as
the voltage measured in step 3.
Check that the TACH VOLTS trimpot is properly calibrated. The motor should run at
the same set speed when SW503 is set to either armature or tachometer feedback.
