7.3 Diagnostic Output Connector (Personality Board - J12)
The mating connector is a Molex 51090-0800 connector with (8) Molex 50212-8000
or 50212-8100 pins. The pins should be used with AWG 24–30 wire.
The diagnostic output connector
(J12)
provides several output signals that are used to
monitor various functions of the servo and galvanometer. See the output signal
specifications in Section 4 for more details.
Diagnostic Output and Servo Enable Connector – J12 (Optional)
7.3.1 Position Output
The position output signal
(J12, Pin 1)
provides a scaled instantaneous position output
from the galvanometer that is buffered through an amplifier. The signal may be used to
trigger an event when a position is reached or used when tuning the servo driver.
7.3.2 Position Error Output
The position error output signal
(J12, Pin 2)
is the difference between the command
input signal and the position signal. It can be used to signal the arrival at a command
location or as a tracking offset (continuous position error).
7.3.3 AGC Monitor
The AGC signal
(J12, Pin 3)
is a voltage that drives the galvanometer position
detector’s oscillator. If found to be excessive, this could suggest position detector
problems.
Pin No.
