Gemini GV Hardware Installation Guide
Configuration
You can configure the Gemini drive’s settings for optimum system performance.
For most of these settings, configuration is optional—if you do nothing, the drive
will use default values the very first time it powers up. If you change any settings,
the new settings are saved automatically. Most changed settings are effective
immediately, but some require that you issue a reset (software RESET command,
reset input, or cycle power) before the drive acts upon them.
This chapter will give an overview of all software commands that configure drive
settings. For more in depth descriptions about the software commands, see the
separate Gemini Programmer's Reference.
At the end of this chapter, we have provided tuning procedures you can use to
configure the Gemini drive’s tuning settings.
Software Programs for Configuration
Two software programs are located on the Motion Planner CD-ROM. Motion
Planner runs on a personal computer (PC). Pocket Motion Planner runs on a palm
PC or Handheld Personal Computer (HPC) that uses Windows CE 2.0 or higher,
or on a PC. These programs are also available on the Compumotor web site at
http://www.compumotor.com.
Information about installing and using each of these software tools can be found in
the Gemini Programmer's Reference.
Overview of Configuration Commands
Motion Planner and Pocket Motion Planner’s configuration procedures present
commands in groups organized by function. The overview below is organized
similarly to the software’s Full Configuration procedure. (Express Setup, which
was discussed in Chapter 2 Installation, gives you fewer configuration options.)
Motor Settings
If you select a Compumotor motor from the list of motors the software presents to
you, the software will send settings to the drive for the motor you selected. No
further motor setting configuration is necessary on your part.
If you use a non-Compumotor motor, or choose to manually configure a
Compumotor motor, use the following commands to configure motor settings.
Also see Appendix B – Using Non-Compumotor Motors for additional instructions.
