Trips Table
The following trips may occur to protect the inverter. The “STATE” can be read through Modbus.
STATE FAULT NAME MEANING POSSIBLE REASON FOR TRIP
0 OK
1 OVERVOLTAGE The Inverter internal DC link voltage is too high.
The supply voltage is too high.
Failure to synchronize properly to the line
2 UNDERVOLTAGE The Inverter internal DC link voltage is too low.
The supply voltage is too low.
The supply voltage is missing.
Grid cables too long.
Possible maintenance required.
3 OVERCURRENT
The output current being drawn from the Inverter
is too high.
Short circuit of the output.
Excessive line disturbance.
Possible maintenance required.
4 HEATSINK The inverter heatsink is too hot.
Excessive ambient temperature.
Cooling fan failure.
Module assembly defect--maintenance required.
17 MOTOR OVERTEMP Filter inductor temperature is too high.
Excessive load.
Prolonged operation without forced cooling (check cooling fan
health)
Check setting of INVERT THERMIST parameter in I/O TRIPS
menu.
Break in filter inductor thermostat wire or defective thermostat.
24 DESAT OVER I
Abnormally high voltage drop across IGBT(s) due
to excessive current within IGBT module
Short circuit of the output.
Excessive line disturbance.
Possible maintenance required.
25 VDC RIPPLE Excessive DC link ripple
Defective DC supply.
Poor DC supply connection.
41 STACK TRIP
The inverter was unable to distinguish between an
overcurrent/desat or overvoltage trip
Short circuit of the output.
Excessive line disturbance.
Possible maintenance required.
