84 Jetter AG
F 20 Undervoltage
DC link voltage
The DC link
voltage is less
than the minimum
value
– Stop with
emergency
stop ramp
– Check the voltage of
the power line
– Check the parameter
"U
ZK
min. trip"
– Acknowledge failure
F 21 Overvoltage DC
link voltage
The DC link
voltage has
exceeded the
maximum value
– Stop with
emergency
stop ramp
– Check the voltage of
the power line
– In generator
operation reduce
braking power
– Acknowledge failure
F 22 The drive has
stalled
The drive could
not overcome the
n=0 threshold
within the time
limit specified by
the parameter
"blocking-triping
time"
– Immediate
locking of
controller
– Eliminate the cause
of stalling
– Acknowledge failure
F 23 Tracking error The tracking error
has exceeded the
limit defined in the
parameter
"tracking error
limit" for the time
specified in
"tracking window
time"
– Stop with
emergency
stop ramp
– Check the drive
mechanism
– Check steepness of
acceleration/
deceleration ramps
and amplifier
parameters in
relation to the
parameters "tracking
error limit" and
"tracking window
time"
– Acknowledge failure
F27
(combined with
F01)
Internal supply
error
one or more
internal supply
voltages has fallen
below their limit
– Immediate
locking of
controller
– Note the number of
error
– Return the amplifier
for repair
F28 Error in power
charging circuit
The input current
limitation circuit is
defective.
– Immediate
locking of
controller
– Check the voltage of
the power line
– Note the number of
error
– Return the amplifier
for repair
F29 Mains power too
high
The average
mains power is too
high
– Immediate
locking of
controller
– Acknowledge failure
– Reduce the average
load of the motor
