CODE ALARM CAUSE WHAT TO DO
A2001
OVERCURRENT
(programmable fault
function, parameter
1610 DISPLAY
ALARMS)
Output current limit controller is
active. Check motor load.
Check acceleration time (parameters 2202
ACCELER TIME 1 and 2205 ACCELER
TIME 2).
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 138 .
A2002 OVERVOLTAGE
(programmable fault
function, parameter
1610 DISPLAY
ALARMS)
DC overvoltage controller is
active. Check deceleration time (parameters 2203
DECELER TIME 1 and 2206 DECELER
TIME 2).
Check input power line for static or transient
overvoltage.
A2003 UNDERVOLTAGE
(programmable fault
function, parameter
1610 DISPLAY
ALARMS)
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, parameters
3001 AI<MIN
FUNCTION, 3021 AI1
FAULT LIMIT)
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 138 .
Check air flow and fan operation.
Check motor power against drive power.
A2010
MOTOR TEMP
(programmable fault
function, parameters
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, parameters
3013 ... 3015 )
Motor load is too low due to, for
example, release mechanism in
driven equipment. Check for problem in driven equipment.
Check fault function parameter settings.
Check motor power against drive power.
A2012
MOTOR STALL
(programmable fault
function, parameters
3010 ... 3012 )
Motor is operating in stall region
due to, for example, excessive
load or insufficient motor power. Check motor load and drive ratings.
Check fault function parameter settings.
