GT6K Steppers – Commands for Configuration
If you use a non-Compumotor motor, you must configure the drive for your motor
by setting values for all commands in the following table. Also see the
Motor
Parameters
table on the
Motion Planner CD-ROM
for examples of recommended
drive configuration settings for Compumotor motors.
Command
Description
DMTSTT
static torque
DMTIC
continuous current
DMTIND
inductance
DMTRES
phase resistance
DMTJ
rotor inertia
DPOLE
number of pole pairs
DIGNA*
current loop gain
DIGNB*
current loop gain
DIGNC*
current loop gain
DIGND*
current loop gain
*See the
Gemini GV6K/GT6K Command Reference for instructions on calculating DIGN
values
Use Motion Planner to enter these command settings into the drive’s memory. See
the
Gemini GV6K/GT6K Command Reference
for more information on commands.
Step Motor Requirements
We recommend that you use Compumotor step motors with the GT6K drive. If
you use a non-Compumotor motor, it must meet the following requirements:
•
Inductance:
minimum:
0.5 mH
recommended:
5.0 – 50.0 mH
maximum:
100.0 mH
•
A minimum of 500VDC high-pot insulation rating from phase-to-phase and
phase-to-ground.
•
The motor must be designed for use with a bipolar drive (no common center tap).
•
The motor must not have riveted rotors or stators.
•
Do not use solid rotor motors.
•
Test all motors carefully. Verify that the motor temperature in your application is
within the system limitations.
The motor manufacturer’s maximum allowable motor
case temperature must not be exceeded. You should test the motor over a 2-to-3
hour period. Motors tend to have a long thermal time constant, but can still
overheat, which results in motor damage.
CAUTION
Consult your motor vendor to verify that your motor meets the above specifications.
Consult your Automation Technology Center (ATC) if you have questions regarding
the use of a non-Compumotor motor with Compumotor equipment.
