Analog Monitors
You can configure the analog outputs to monitor many different variables, such as
current, velocity, temperature, etc. You can also scale the outputs. See the DMON
commands in
Chapter 3 Configuration
and the
Gemini GV6K/GT6K Command
Reference
for more information.
WARNING
Do not use Analog Monitors as control signals. Because of offsets, limited resolu-
tion and accuracy, use the analog monitor outputs only for oscilloscope monitoring.
Analog Input (optional)
An analog input is available on pins 23 and 24. Use pin 25 as a ground reference
for the analog input.
Connection Instructions for the Analog Input:
1.
Connect Analog Input+ to pin 23.
2.
Connect Analog Input- to pin 24.
3.
Connect your analog source’s ground reference to pin 25.
These connections are illustrated in the next drawing.
