To get started, the 590+ manual has an extensive amount of troubleshooting assistance. If you are getting unwanted behavior or have a fault, then a dedicated section called "TRIPS AND FAULT FINDING" is the fantastic starting location to solving your problem. The manuals are thorough, and are firmware dependent.
Manuals can be found on the 590+ on Parker.com under the "Product Support" tab. Accessory manuals (such as tech option cards) also have separate manuals associated with them.
"Trips and Fault Finding" section offers (but is not limited to):
- Trips/Faults/Error Codes understanding on the keypad.
- There is a breakdown of trips and possible solutions in the manual to try first.
- Flow-Chart Check Guides for:
- General operation
- Hardware troubleshooting
- Field failures
- Contactor failures
- SCR troubleshooting
- Motor checks
- Alarm Status parameter information well as Diagnostics Information (both on the keypad or in DSELite)
- You may view if there are other present Alarms, if there are issues with parameters related to the issue, or a distinguishable pattern within the alarm history.
- Note: It is common to see "Undervoltage" trips after power-down. If seeing "Undervoltage" during operation that is an issue.
After consulting the manual:
Try checking out the FAQs in the sidebar under "590+" to see if your issue has any write ups on it from an applications engineer.
- If an article relevant to your issue is already posted, Parker Support would have you walk through it to gather more information or narrow down a root cause to start with.
After consulting the sidebar:
- Do you have the proper measuring devices if relevant to the issue (Oscilloscope, current clamp, etc?)
- Are you able to narrow the issue down to one part of the machine?
- Have you tried swapping hardware if pertinent?
- Is one side of the machine working but another not?
- Is the drive getting proper signals from external sources? (Potentiometer, PLC, contactors, power supply, etc)
- As an example; questions for a drive that does not want to start running from a fieldbus command would be: Is your PLC sending the proper control and status words? If so, is the drive accepting those parameters as viewable within DSELite? If further so, then the issue may be programming logic not executing properly or you are missing various bits to send. If your PLC was not sending proper control and status words initially, that's a PLC issue.
- Use the DSELite software to view your programming. If no fault is present but you are getting unwanted behavior, you can extract the programming and then view it Online to see changes in real time with debugging tools, or view how the machine's parameters are designed to interact.
- What Software and Communication Cable are used for Programming?
- How do I Extract Parameters from a 590+ to View Them?
- DSELite has Help files at the top of the window and within every function block to understand your programming and how it is executing.
