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
