CODE ALARM CAUSE WHAT TO DO
2001 OVERCURRENT
(2310)
0308 bit 0
(programmable fault
function
1610 )
Output current limit
controller is active. Check motor load.
Check acceleration time (
2202 and 2205 ).
Check motor and motor cable (including phasing).

(3210)
0308 bit 1
(programmable fault
function
1610 )
DC overvoltage controller
is active. Check deceleration time ( 2203 and 2206 ).
Check input power line for static or transient overvoltage.
2003 UNDERVOLTAGE
(3220)
0308 bit 2
(programmable fault
function
1610 )
DC undervoltage controller
is active. Check input power supply.
2004 DIRLOCK
0308 bit 3
Change of direction is not
allowed. Check parameter 1003 DIRECTION settings.

(programmable fault
function
3018 ,
3019 )
Fieldbus communication
break Check status of fieldbus communication. See chapter
Fieldbus control with fieldbus adapter / Fieldbus control with
embedded fieldbus or appropriate fieldbus adapter manual.
Check fault function parameter settings.
Check connections.
Check if master can communicate.
2006 AI1 LOSS
(8110)
0308 bit 5
(programmable fault
function
3001 ,
3021 )
Analog input AI1 signal has
fallen below limit defined by
parameter
3021 AI1 FAULT
LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
2007 AI2 LOSS
(8110)
0308 bit 6
(programmable fault
function
3001 , 3022 )
Analog input AI2 signal has
fallen below limit defined by
parameter
3022 AI2 FAULT
LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
2008 PANEL LOSS
(5300)
0308 bit 7
(programmable
fault function
3002 )
Control panel selected as
active control location for
drive has ceased
communicating. Check panel connection.
Check fault function parameters.
Check control panel connector.
Refit control panel in mounting platform.
If drive is external control mode (REM) and is set to accept
start/stop, direction commands or references via control
panel:
Check group
10 START/STOP/DIR and 11 REFERENCE
SELECT settings.
