list of the meanings of the numbers in that display:

0 All conditions nominal

1 Undervoltage trip .................................................Line voltage dropped below minimum level

2 Overvoltage trip of drive......................................Bus voltage exceeded safe limit

3 Undervoltage timer tripped ..................................Line voltage low for too long

4 Instantaneous overcurrent ....................................Excessive transistor current

5 Loss of encoder signal..........................................Encoder speed signals lost.

Encoder loss detection applies only when pulse

multiplier is set to 4X

6 Motor thermal tripped ..........................................Motor is too hot or thermal is disconnected

7 Commutation fault ...............................................Signals from position encoder lost

8 +24VDC lost at TB2-A14 and TB2-B1 ...............Fuse FR1 overloaded

9 +24VDC lost at TB3-B1 ......................................Fuse FR2 overloaded

A +5VDC lost at TB1-A8 ........................................Fuse FR4 overloaded

B +24VDC lost at TB1-A10 ....................................Fuse FR3 overloaded
