Fault tracing 47
Fault messages
Code Fault Cause What to do
D100 Emergency
stop
Emergency activated. See parameter 74.08
Emergency stop select to
activate or deactivate the
emergency stop with any
particular DI.
D101 Max operation
speed
Speed actual is beyond the
value set in 78.01 SPRS max
speed %.
• Monitor the parameter
09.03 Speed actual [%].
• Compare it to the Max
Speed limit set in
parameter 78.01 SPRS
max speed %.
• Change the speed
reference till the speed
actual is below the limit
and reset the drive.
D102 Rotor over
voltage
Rotor voltage is greater than
the value set in parameter
78.03 Rotor over voltage limit.
• Monitor the parameter
74.16 Rotor over voltage
select, the DI assigned
to detect rotor over-
voltage fault.
• Check the circuit
connected to the chosen
DI for faults.
D103 Earth fault Earth fault relay sensed earth
fault in the converter.
See parameter 74.17 Earth
fault select, the DI
assigned to detect earth
fault. Also check the circuit
connected to the chosen
DI.
D104 Over current
fault
Output current is beyond the
trip current limit.
See parameter 74.13 Over
current relay, the DI
assigned to detect Over
Current Relay pick
condition. Also check the
circuit connected to the
chosen DI.
D105 Min operation
speed
Speed actual is below the value
set in 78.02 SPRS min speed
%.
Monitor the parameter
09.03 Speed actual [%].
Increase the speed limit to
at least more than one
value set in 78.02 SPRS
min speed %.
