Gemini Products—Overview
The Gemini Series is a family of high performance digital drives. The family
contains drives for both stepper and servo motors. With many models and options
available, the user can choose the precise level of power and control for the
application’s motion requirements.
Gemini Product Descriptions
Gemini GT and GV
Gemini GT Stepper Drives and GV Servo Drives are the basic Gemini products.
They are controlled with standard command interfaces of step/direction or ±10V,
and can be used with standard indexers or controllers.
The drives are configured over RS-232/485 with either Motion Planner on a
personal computer (PC), or Pocket Motion Planner on a palm PC. Many advanced
features are standard in the drives, such as sensorless stall detect and ABS damp-
ing in the GT, and digital tuning and notch filters in the GV.
Gemini GT6 and GV6
The Gemini GT6 and GV6 are controller/drives available with several different
programming modes. These drives have basic motion control and sequencing
capabilities, and can be used in distributed control applications. By using optional
plug-in cards, they can be equipped with interfaces for SERCOS, Profibus,
Interbus-S, and other industry standard fieldbus networks.
The GT6 and GV6 are configured and programmed over RS-232/485, either with
Motion Planner on a PC, or Pocket Motion Planner on a palm PC.
GT6 or GV6 drives are also available with an optional SERCOS interface. These
drives can be configured via the acyclic channels of the motion bus, or via the RS-
232/485 port using the tools mentioned above.
Gemini GT6K and GV6K
The Gemini GT6K and GV6K are single axis packaged controller/drives that offer
full 6K Series controller functionality and programmability for complex distrib-
uted control applications. Key features include: complex program capabilities such
as math, variables, and logic control; flexible and expandable serial I/O modules;
and Ethernet compatibility for PC bus access. The user programs these devices
over an RS-232/485 communication port; a second port is available for use with a
full-time operator interface.

You will connect together only the components necessary to achieve basic
motion—a drive, a motor (without a load connected), and cables. You will use a
computer to communicate with the drive.

Chapter 2 – Installation 11
In the express setup, we will give procedures for the following steps:
1. Connecting the motor to the drive (without a load connected)
2. Connecting AC power to the drive
3. Establishing communications and configuring the drive for autorun
4. Enabling the drive and observing the motor turn
Information you may need for final installation will be presented in Chapter 3

Step 1 – Connecting the Motor
The Gemini drive is compatible with 4, 6, or 8 lead step motors designed for use
with a bipolar drive.
Connecting the Motor
Make sure power is off before you connect the motor.
1. Wire your motor in series or parallel.
For wiring diagrams, color codes, dimensions and speed/torque curves for
Compumotor motors, consult the separate Gemini Motor Reference Manual .
If you use a non-Compumotor motor, see Appendix B Using Non-Compumotor
Motors for instructions on preparing your motor for connection to the Gemini drive.
2. Prepare four motor phase wires to connect to the Gemini drive, and identify them as
A+, A-, B+, and B-.
3. Remove the clear plastic cover from the drive terminals. Connect the motor cable’s
earth wire to the drive terminal with the symbol. This connects the motor’s
protective conductor terminal to the drive’s safety earth.
4. Connect your motor cable’s phase wires (A+, A-, B+, B-) to the drive’s A+, A-, B+,
B- terminals, respectively, as shown in the drawing below.
WARNING
The drive’s barrier strip terminals are at hazardous voltages when power is
applied to the drive, and up to 30 seconds after power is removed.
Reinstall the clear plastic terminal cover after you make connections.
5. Secure the motor cable to the drive by placing the exposed cable shield in the
saddle clamp on the bottom of the drive. Make the loop of cable between the saddle
clamp and the drive terminals as short as possible.

Step 3 – Configuring the Drive
Gemini drives have no DIP switches or potentiometers for configuration. You will
use software tools to communicate with the drive and configure drive settings.
Configuration Software
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.
Establishing Communications
We assume you are using a Gemini GT6 drive and that you have only one serial
port on your PC.
WARNING
This procedure causes the motor shaft to move. Do not connect a load to the shaft.
1. Verify that a load is not connected to the motor, and that the motor is clamped
securely in place.
2. Verify that a cable is not attached to the DRIVE I/O connector.
3. Using a null modem cable, connect the drive’s RS-232/485 connector to the serial
port on your PC, palm PC, or HPC. (A null modem cable is available from Compu-
motor. See Appendix A Specifications for more information.) It is not necessary to
turn off AC power before you plug in an RS-232 cable; however, connect RS-485
cables before applying AC power.

Appendix A Specifications .)
2. Issue the following command to the drive:
DRIVE1 (enables the drive)
3. Verify that the drive is enabled. (Left LED is illuminated green; right LED flashes
yellow/green during autorun.)
4 Verify that the motor is rotating clockwise at approximately one revolution per
second, as viewed from the shaft end of the motor. (The motor is turning because
earlier you configured the drive for autorun.)
Proceed to Commanding Motion Under Program Control.
Commanding Motion Under Program Control
In this procedure you will use the Gemini command language to make the motor
turn. This will verify that your system is installed correctly.
1. Issue the following commands to change the drive mode and verify correct
resolution:
DRIVEØ (disables the drive and stops motion)
DMODE12 (changes mode from autorun to controller/drive mode)
DRIVE1 (enables the drive)
2. Issue the following commands to the drive to make the motor turn:
LHØ (disables limits)
MAØ (enables incremental positioning mode; disables absolute mode)
MCØ (enables incremental positioning mode; disables continuous mode)
A10 (sets acceleration to 10)
V1 (sets velocity to 1)
D25000 (sets distance to 1 rev (if DRES = 25000) )
GO (initiates motion)
3. Verify that the motor rotates one revolution and then stops.
This completes the Express Setup procedure.
