The DFS-1 has a single-digit alphanumeric display to show error codes when something is wrong. Following is a 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

C

Current limit

Drive is at maximum current output

D

Timed Overload

Timed overcurrent has occured

E

Display fault

Fault in display module

F

Applications fault

Fault in applications program
