ZETA6xxx Installation Guide
Troubleshooting Basics
When your system does not function properly (or as you expect it to operate), the first thing
that you must do is identify and isolate the problem. When you have accomplished this,
you can effectively begin to resolve the problem.
The first step is to isolate each system component and ensure that each component functions
properly when it is run independently. You may have to dismantle your system and put it back
together piece by piece to detect the problem. If you have additional units available, you may
want to exchange them with existing components in your system to help identify the source of
the problem.
Determine if the problem is mechanical, electrical, or software-related. Can you repeat or re-
create the problem? Random events may appear to be related, but they are not necessarily
contributing factors to your problem. You may be experiencing more than one problem. You
must isolate and solve one problem at a time.
Log (document) all testing and problem isolation procedures. You may need to review and
consult these notes later. This will also prevent you from duplicating your testing efforts.
Once you isolate the problem, refer to the problem solutions contained in this chapter. If the
problem persists, contact your local technical support resource (see Technical Support below).
Reducing Electrical Noise
Refer to the guidelines on page 26. General information on reducing electrical noise can be
found in the Engineering Reference section of the Parker Compumotor/Digiplan catalog.
Appendix D (page 63) provides guidelines on how to install the ZETA6xxx in a manner most
likely to minimize the ZETA6xxx’s emissions and to maximize the ZETA6xxx’s immunity to
externally generated electromagnetic interference.
Diagnostic LEDs
POWER
................ On (green) if 120VAC (or 240 VAC for 240V versions) connected. Off if
no power.
STEP
................... Flashes on (green) with each pulse sent to the motor. Off if no pulses.
OVER TEMP
......... On (red) if internal sensor reaches 122°F (50°C). Off = O.K.
MOTOR FAULT
..... On (red) if there is a short in the motor windings, if the motor cable is
disconnected or shorted, or if the INTERLOCK jumper on the MOTOR
connector is removed or extended. Off = O.K.
Test Options
•
Test Panel. Motion Architect’s Panel Module allows you to set up displays for testing
system I/O and operating parameters. Refer to the Motion Architect User Guide for details.
•
Hardware Test Procedure (see pages 27-29).
•
Motion Test. A test program is available to verify that the ZETA6xxx is sending pulses to
the motor and that the motor is functioning properly. The test program can be initiated by
issuing the
TEST
command over the serial interface, or by accessing the RP240
TEST
menu (see 6000 Series Programmer’s Guide for RP240 menu structure).
WARNING
The
TEST
program causes the end-of-travel limits to be ignored. If necessary, disconnect
the load to ensure the test moves do not damage your equipment or injure personnel.
