Description
Brake feedback has timed out. The feedback
signal is indicating that the mechanical brake
has not opened or closeed within the config-
ured time.
The control board cooling fan is not running
at the commanded speed.
The main cooling fan is not following its ref-
erence speed. Check the fan's wiring and
whether its blocked or polluted. Replace the
fan if necessary.
The internal fan is running below its reference
speed. Check the fan's wiring and whether its
blocked or polluted. Replace the fan if neces-
sary.
LCL cooling fan not tracking commanded
output.
The Brake Resistor Test is active. Normal run
of the drive is not possible.
The Brake Resistor Test was unsuccessful.
Check the brake resistor and its connections.
The test of the brake resistor is performed
successfully.
A short circuit of the brake chopper switch
has been detected, which can be dangerous.
Disconnect power. Service is required.
A brake chopper overcurrent has been de-
tected. Reduce the brake voltage level and
check the rating of the brake resistor.
The brake resistor temperature is too high.
Check the rating of the brake resistor and
cooling conditions. Reduce the generated re-
generative power.
The brake resistor or its connection is missing.
