B 4.6 Description of all errors and warnings

W = Warning message, inverter still ready for operation
E= Error message, serious fault, inverter not ready for operation, a reset must be triggered
No. Description
1 W Warning. Motor current has
reached the current limit
P44-I_limit
( )
2 E Temperature monitoring
Motor
3 E Temperature monitoring
Inverter cooler
4 E Inverter output current
too large (15A)
5 E Inverter overcurrent protection
Generator operation (15A)
6 E Voltage monitoring Interme-
diate circuit voltage (380V)
7 E Monitoring Mains undervoltage
8 E Monitoring Mains overvoltage
9 E Overcurrent protection in
inverter (peak current)
10 E Overcurrent protection
DC chopper
11 W Monitoring Brake resistance
12 E Monitoring brake resistance
13 W Nominal speed limit active.
The internal nominal speed
of the motor control

14 W Motor emergency stop is ac-
tivated.
Cause
Motor too highly loaded, rise time
P46-t_rise
too short, startup
P52-I_start
current
Motor too hot, possibly sensor cable
break
Inverter overloaded, cooler too hot
Motor current too high, overload
Generator current too high
ASM motor fall time too short
Mains voltage too low
Mains voltage too high
Inverter overloaded, motor short-cir-
cuit or earth fault
Device error in inverter
Bridge at X6.2-3 for internal brake resi-
stance missing
Bridge at X6.2-3 for internal brake resi-
stance connected but external brake
resistance configured
P1-f_rated
or rated value of
analogue input too high
) is
Mains voltage interruption or mains
input voltage too low.

Check rated parameter value
P1-f_rated
rated value for remote control
P135-f_rem_min
P136-f_rem_max
frequencies P104 ... P107, for
checking the current rated value
