Description
The DC link voltage
is less than the
minimum value
The DC link voltage
has exceeded the
maximum value
The drive could not
overcome the n = 0
threshold within the
time limit specified
by the parameter
"blocking-triping
time"
The tracking error
has exceeded the
limit defined in the
parameter "tracking
error limit" for the
time specified in
"tracking window
time"
External 24 V supply
was lower than 18 V
one or more internal
supply voltages has
fallen below their
limit
The average mains
power is too high
Effect Error Correction
– Stop with – Check the voltage of
emergency the power line
stop ramp – Check the parameter
"U
– Acknowledge failure
– Stop with – Check the voltage of
emergency the power line
stop ramp – In generator
operation reduce
braking power
– Acknowledge failure
– Immediate – Eliminate the cause
pulse disable of stalling
– Acknowledge failure
– Stop with – Check the drive
emergency mechanism
stop ramp – Check steepness of
acceleration/
deceleration ramps
and amplifier
parameters in relation
to the parameters
"tracking error limit"
and "tracking window
time"
– Acknowledge failure
– Immediate – Check external power
pulse disable supply
– Acknowledge failure
– Immediate – Note the number of
pulse disable error
– Return the amplifier
for repair
– Immediate – Acknowledge failure
pulse disable – Reduce the average
load of the motor
