Alarm messages generated by the drive
CODE ALARM CAUSE WHAT TO DO
A2001 OVERCURRENT
(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 114.
A2002 OVERVOLTAGE
(programmable
fault function 1610)
DC overvoltage controller is
active.
Check deceleration time (2203 and 2206).
Check input power line for static or transient
overvoltage.
A2003 UNDERVOLTAGE
(programmable
fault function 1610)
DC undervoltage controller is
active.
Check input power supply.
A2004 DIRLOCK Change of direction is not
allowed.
Check parameter 1003 DIRECTION settings.
A2006 AI1 LOSS
(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.
A2009 DEVICE
OVERTEMP
Drive IGBT temperature is
excessive. Alarm limit is 120°C.
Check ambient conditions. See also section Derating
on page 114.
Check air flow and fan operation.
Check motor power against unit power.
A2010 MOTOR TEMP
(programmable
fault function
3005...3009)
Motor temperature is too high (or
appears to be too high) due to
excessive load, insufficient motor
power, inadequate cooling or
incorrect start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameter settings.
Let motor cool down. Ensure proper motor cooling:
Check cooling fan, clean cooling surfaces, etc.
A2011 UNDERLOAD
(programmable
fault function
3013
...3015)
Motor load is too low due to e.g.
release mechanism in driven
equipment.
Check for problem in driven equipment.
Check fault function parameter settings.
Check motor power against unit power.
A2012 MOTOR STALL
(programmable
fault function
3010...3012)
Motor is operating in stall region
due to e.g. excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameter settings.
A2013 AUTORESET Automatic reset alarm Check parameter group 31 AUTOMATIC RESET
settings.
A2017 OFF BUTTON Drive stop command has been
given from control panel when
local control lock is active.
Disable local control mode lock by parameter 1606
LOCAL LOCK and retry.
A2023 EMERGENCY
STOP
Drive has received emergency
stop command and ramps to stop
according to ramp time defined by
parameter 2208 EMER DEC
TIME.
Check that it is safe to continue operation.
Return emergency stop push button to normal
position.
