Fault Queue for Drive Diagnostics
For general ACH550 diagnostics information, see “Diagnostics” in the ACH550
User’s Manual. The three most recent ACH550 faults are reported to the fieldbus as
defined below.
Serial Communication Diagnostics
Network problems can be caused by multiple sources. Some of these sources are:
• Loose connections
• Incorrect wiring (including swapped wires)
• Incorrect baud rate
• Bad grounding
• Duplicate station numbers
• Incorrect setup of drives or other devices on the network
The major diagnostic features for fault tracing on an EFB network include Group 53
EFB Protocol parameters 5306…5309. The “Parameter Descriptions” section, in the
ACH550 User’s Manual, describes these parameters in detail.
Diagnostic Situations
The sub-sections below describe various diagnostic situations – the problem
symptoms and corrective actions.
Normal Operation
During normal network operation, 5306…5309 parameter values act as follows at
each drive:
• 5306 EFB OK MESSAGES advances (advances for each application message
properly received and addressed to this drive).
• 5307 EFB CRC ERRORS does not advance at all (advances when an invalid
message CRC is received).
• 5308 EFB UART ERRORS does not advance at all (advances when character format
errors are detected, such as parity or framing errors).
• 5309 EFB status value varies depending on network traffic.

- Changes made to drive parameter group 53 efb protocol do not take affect until you perform one of the following 11
- Cycle the drive power off and on or 11
- Enable bacnet protocol set drive parameter 9802 11
- It should read x5xx where x is any value 11
- Note if you cannot see the desired selection on the panel your drive does not have that protocol software in the application memory 11
- Quick start sequence 11
- Set parameter 5302 to 0 and then back to a unique mac id or 11
- Start up 11
- The following steps summarize the process for enabling and configuring bacnet on the ach550 11
- To confirm this selection read drive parameter 5301 11

- Feedback from the drive 15
- Has a resolution of 0 sec which means that in the drive and in the mailbox the value 1 0 seconds so a mailbox value of 10 translates to 1 second a mailbox value of 300 translates to 30 seconds etc refer to the parameter listing in the ach550 user s manual for each parameter s resolution and units of measure 15
- Inputs to the controller drive outputs have pre defined meanings established by the protocol this feedback does not require drive configuration the following table lists a sample of feedback data for a complete listing see input word point object listings in the technical data section 15
- Mailbox read write 15
- Note relay status feedback occurs without configuration as defined below 15
- Note you must read and write mailbox values using the drive s internal scaling for example the parameter 2202 15
- Pre defined feedback 15
- Relay 1 3 status bi0 bi1 bi2 15
- Relay 4 6 status bi3 bi4 bi5 15
- Start up 15
- The ach550 provides a mailbox function to access parameters that have not been pre defined by the protocol using mailbox any drive parameter can be identified and read mailbox can also be used to adjust parameter settings by writing a value to any parameter identified the following table describes the use of this function 15
