CODE ALARM CAUSE WHAT TO DO
2001
OVERCURRENT 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).
Check ambient conditions. Load capacity decreases if
installation site ambient temperature exceeds 40 °C.
See section Derating on page 103.
2002
OVERVOLTAGE 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 0308 bit 2
(programmable
fault function 1610)
DC undervoltage controller is active. Check input power supply.
2004 DIR LOCK 0308 bit 3 Change of direction is not allowed. Check parameter 1003 DIRECTION settings.
2005
IO COMM 0308 bit 4
(programmable
fault function 3018, 3019)
Fieldbus communication break
Check status of eldbus communication.
See chapter Fieldbus control with embedded eldbus
on page 70.
Check fault function parameter settings.
Check connections.
Check if master can communicate.
2006
AI1 LOSS 0308 bit 5
(programmable
fault function 3001, 3021)
Analog input AI1 signal has fallen below limit dened by
parameter 3021 AI1 FAULT LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
2007
AI2 LOSS 0308 bit 6
(programmable
fault function 3001, 3021)
Analog input AI2 signal has fallen below limit dened by
parameter 3022 AI2 FAULT LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
2008
PANEL LOSS 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. Ret control panel in mounting
platform.
If drive is in external control mode (REM) and is set to accept
start/stop, direction commands or references via control panel:
Check Group 10: AcStart/Stop/Dir and Group 11: Reference
Select settings.
2009
DEVICE OVERTEMP
0308 bit 8
Drive IGBT temperature is excessive. Alarm limit is
120°C.
Check ambient conditions. See also section Derating on page
103.
Check air ow and fan operation.
Check motor power against unit power.
2010
MOTOR TEMP 0305 bit 9
(programmable fault function
3005…3009 / 3503)
Motor temperature is too high (or appears to be too
high) due to excessive load, insufcient motor power,
inadequate cooling or incorrect start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameters.
Measured motor temperature has exceeded alarm limit
set by parameter 3503 ALARM LIMIT.
Check value of alarm limit.
Check that actual number of sensors corresponds to value set
by parameter (2501 SENSOR TYPE).
Let motor cool down. Ensure proper motor cooling: Check
cooling fan, clean cooling surfaces, etc.
2012
MOTOR STALL 0308 bit 11
(programmable fault function
3010…3012)
Motor is operating in stall region due to e.g. excessive
load or insufcient motor power.
Check motor load and drive ratings.
Check fault function parameters.
2013
1
AUTORESET 0308 bit 12 Automatic reset alarm Check parameter Group 31: Automatic Reset settings.
2014
1
AUTOCHANGE 0308 bit 13 PFC Autochange function is active.
2015 PFC I LOCK 0308 bit 14 PFC interlocks are active.
Drive cannot start
• any motor (when Autochange is used)
• the speed regulated motor (when Autochange is not used).
