Name
Output current above limit at motor running at con-
stant speed
Output current above limit at motor accelerating
Output current above limit at motor decelerating
DC bus voltage above limit at motor running at con-
stant speed
DC bus voltage above limit at motor accelerating
DC bus voltage above limit at motor decelerating
DC bus voltage below limit at converter running
Output current sharp increase or short circuit occurs
on motor cable or converter power module has internal
error
Mains cable disconnected or input imbalance occurs
Motor cable disconnected or output imbalance occurs
Soft start circuit is not working properly
Converter load is above limit for too long
Converter temperature is too high
Converter fan is not working properly
PID feedback is excessively low when converter run-
ning at output frequency high limit
Command value from panel is lost
STO function is activated correctly in running mode,
after re-energized input channels and reset the device,
the device goes to normal state
STO function is activated incorrectly, it happens if one
channel is energized but the other is deenergized
Motor load is above limit for too long
Motor temperature is above limit for too long
Error occurs during motor parameter auto-tuning
Error occurs during synchronous motor angle detec-
tion
error occures during encoder connection
The speed loop difference is outside [C3.26] over a
time of [C3.25]
