4.4 Error Code
Nr. Code Name Description
1 OC-1 Overcurrent at constant speed
Output current above limit at motor running at con-
stant speed
2 OC-2
Overcurrent during accelera-
tion
Output current above limit at motor accelerating
3 OC-3
Overcurrent during decelera-
tion
Output current above limit at motor decelerating
4 OE-1 Overvoltage at constant speed
DC bus voltage above limit at motor running at con-
stant speed
5 OE-2
Overvoltage during accelera-
tion
DC bus voltage above limit at motor accelerating
6 OE-3
Overvoltage during decelera-
tion
DC bus voltage above limit at motor decelerating
8 UE-1 Undervoltage during run DC bus voltage below limit at converter running
9 SC Surge current or short circuit
Output current sharp increase or short circuit occurs
on motor cable or converter power module has internal
error
10 IPH.L Input phase loss Mains cable disconnected or input imbalance occurs
11 OPH.L Output phase loss Motor cable disconnected or output imbalance occurs
12 ESS- Soft start error Soft start circuit is not working properly
20 OL-1 Converter overload Converter load is above limit for too long
21 OH Converter over temperature Converter temperature is too high
23 FF Fan failure Converter fan is not working properly
24 Pdr Pump dry
PID feedback is excessively low when converter run-
ning at output frequency high limit
25 CoL- Command value lost Command value from panel is lost
26 StO-r STO request
STO function is activated correctly in running mode,
after re-energized input channels and reset the device,
the device goes to normal state
27 StO-E STO error
STO function is activated incorrectly, it happens if one
channel is energized but the other is deenergized
30 OL-2 Motor overload Motor load is above limit for too long
31 Ot Motor over temperature Motor temperature is above limit for too long
32 t-Er Motor parameter tuning error Error occurs during motor parameter auto-tuning
33 AdE-
Synchronous motor angle de-
tection error
Error occurs during synchronous motor angle detec-
tion
34 EnCE- encoder connection error error occures during encoder connection
35 SPE- Speed control loop error
The speed loop difference is outside [C3.26] over a
time of [C3.25]
