CAUSE
Output current limit controller is
active.
DC overvoltage controller is
active.
DC undervoltage controller is
active.
Change of direction is not
allowed.
Analog input AI1 signal has fallen
below limit defined by parameter
3021 AI1 FAULT LIMIT.
Drive IGBT temperature is
excessive. Alarm limit is 120°C.
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.
Motor load is too low due to e.g.
release mechanism in driven
equipment.
Motor is operating in stall region
due to e.g. excessive load or
insufficient motor power.
Automatic reset alarm
Drive stop command has been
given from control panel when
local control lock is active.
Drive has received emergency
stop command and ramps to stop
according to ramp time defined by
parameter 2208 EMER DEC
TIME.
WHAT TO DO
Check motor load.
Check acceleration time (2202
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.
Check deceleration time (2203
Check input power line for static or transient
overvoltage.
Check input power supply.
Check parameter 1003 DIRECTION settings.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
Check ambient conditions. See also section
on page 114.
Check air flow and fan operation.
Check motor power against unit power.
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.
Check for problem in driven equipment.
Check fault function parameter settings.
Check motor power against unit power.
Check motor load and drive ratings.
Check fault function parameter settings.
Check parameter group 31 AUTOMATIC RESET
settings.
Disable local control mode lock by parameter
LOCAL LOCK and retry.
Check that it is safe to continue operation.
Return emergency stop push button to normal
position.
