11.1.4 AGC Fail / Open Loop Condition

If the red LED is on, there may be a failure in the automatic gain control loop or the
servo loop is open.

11.1.5 Servo Ready Signal

When the servo drive is ready, the Servo Ready Hi output signal (Pin 1 of connector
J8) goes low (0 volts) and the Servo Fault LED (Red, D7) is off. If there is a fault, the
Servo Ready output will go high and the Fault LED (Red, D7) is on. The Servo Ready
Lo output is an inverted version of the Servo Ready Hi output.
