Description
Excessive voltage ripple has been detected
on the main DC-link capacitors. This can be
caused by an imbalance of the grid. Reduce
the output power.
An imbalance across the DC-link capacitors is
detected. The imbalance can be caused by a
component fault of the DC link. If the fault re-
mains after resetting the drive, service is re-
quired.
The ambient temperature is too high. Check
the temperature and cooling conditions.
Lower the temperature or improve the cool-
ing conditions.
The temperatute of the brake chopper heat
sink is at the upper limit of the normal tem-
perature range. Check cooling and heat sink
conditions. Reduce the generated regenera-
tive power.
The temperature of the brake chopper heat
sink has exceeded the normal temperature
range. Check cooling and heat sink condi-
tions. Reduce the generated regenerative
power.
The temperature of the brake chopper heat
sink has reached a critical level. Check cooling
and heat sink conditions. Reduce the gener-
ated regenerative power.
The temperature of the brake chopper heat
sink is too low. Check the ambient temper-
ature. Increase the ambient temperature or
consider an external heater to increase the
temperature around the drive.
Temperature protection 1 is triggered. The
temperature has exceeded the configured
value.
