Gemini GT6 Hardware Installation Guide
Analog Monitor (optional)
Two analog monitor outputs are available on pins 21 and 22. Use pin 25 as a
ground reference for these monitors.
Analog Monitor Specifications:
Maximum Output:
±10V (scalable; use DMON command)
Resolution:
8 bits peak to peak (for full scale signal)

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 Programmer's 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.
Connecting Feedback Devices
Gemini GV6 servo products use the 26 pin MOTOR FEEDBACK connector. The
Gemini GT6 drive does not use the MOTOR FEEDBACK connector. You do not
need to make connections to this connector.
Data Bus I/O Connectors
The 9-pin DATA BUS IN and DATA BUS OUT connectors are used for various
options. The connector pinouts can change, based upon the optional circuit board
that is installed in the drive. For more information, see the user guide for your
particular option.
If your drive does not have an optional circuit board installed, you do not need to
make connections to these connectors.
