For example:
1. Assuming, for the sake of this example, that the Actual Value uses parameter 9908
MOT

SPEED
as the 100% reference, and that 9908 = 1500 rpm.
2. Assuming, for the sake of this example, that the Actual Value uses parameter 9907
MOT
NOM
FREQ
as the 100% reference, and that 9907 = 500 Hz.
Diagnostics – EFB
Fault Queue for Drive Diagnostics
For general ACS510 diagnostics information, see "Diagnostics" starting on page
196. The three most recent ACS510 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)
• 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 "Complete Parameter Descriptions"
section describes these parameters in detail.
