TQ10X User Guide
8. Test Your System
Except for connecting the motor to the load, system installation should be complete
at this point. Perform the test procedure below to verify that your system is func-
tioning properly.
In the test procedure, you will command single revolution moves in the clockwise
and counterclockwise direction. If your mechanics do not permit such moves,
choose a move that allows you to easily verify correct system response.
CAUTION
If you have an SM or NeoMetric Motor, use the drive’s DIP switches to set the peak current
at twice the motor’s continuous current rating, or less. Motor damage due to excessive
heating may result from the combination of high peak current and improper tuning values.
Test Procedure
➀
Apply 120VAC power. The bicolor LED labeled GRN = POWER ON should be
illuminated green.
➁
Command a slow move of one revolution in the clockwise direction. Verify that the
motor turns as commanded. (If you have not connected hardware limit switches,
send the command LD3 to disable limits, before you send a GO command.)
➂
Command a slow move of one revolution in the counterclockwise direction. Verify
that the motor turns as commanded.
➃
Test any of the optional inputs and outputs that you have connected.
You may need to tune your system before you can obtain motion from the motor.
See Chapter 4 Tuning for tuning instructions.
Successful completion of this procedure will verify that your motor and encoder
are correctly connected to the TQ10X, and that the drive is functioning properly.
If the test was unsuccessful, observe the LEDs on the front panel of the TQ10X
while you try the test procedure—they may indicate the cause of the problem.
(Chapter 6 Troubleshooting has a complete description of LED functions.) Review
earlier sections of this user guide, verify that you have completed each step, and try
this test procedure again.
If the test is still unsuccessful, proceed to Chapter 6 Troubleshooting for problem
identification and solution procedures.
9. Connect the Motor to the Load – Couplers
Your mechanical system should be as stiff as possible. Because of the high torques
and accelerations of servo systems, the ideal coupling between a motor and load
would be completely rigid. Rigid couplings require perfect alignment, however,
which can be difficult or impossible to achieve. In real systems, some misalign-
ment is inevitable. Therefore, a certain amount of flexibility may be required in the
system. Too much flexibility can cause resonance problems, however. These
conflicting requirements are summarized below.
•
Maximum Stiffness (in the mechanical system)
•
Flexibility (to accommodate misalignments)
•
Minimum Resonance (to avoid oscillations)
The best design may be a compromise between these requirements.
