CDHD Troubleshooting
User Manual 43
Display Fault Name Description Action Required
r23 Phase Find Failed Commutation initialization has
failed. This fault occurs in systems
that do not have commutation
information (e.g., Hall signals) in the
motor feedback device.
Check whether the motor feedback
type and the phase-finding parameters
are set correctly for the application.
r24 Tamagawa Init
Failed
The initialization process with the
Tamagawa feedback device has
failed.
Check that the wiring to the encoder is
correct.
r4 A/B Line Break
One of the primary feedback signals
is not connected. This fault occurs in
incremental encoder, resolver and
sine encoder feedback types.
Check whether all signals from the
primary feedback device are properly
connected to the drive.
r5 Index Line Break Encoder index line is not connected. Check that the drive is configured for
working with the index signal (using
MENCTYPE), and check if the index
signal is connected.
r6 Illegal Halls The drive has detected either 000 or
111 state on the Hall feedback
signals.
Check that the Hall signals are all
properly connected. While turning the
motor, read the Halls state (using
HALLS) to see which signal is not
connected.
r8 A/B Out of Range Feedback analog signal is out of
range. This fault is related to
resolver and sine encoder feedback.
The drive checks that the amplitudes
of the sine and cosine signals are
correct, based on the calculation sin
2
+ cos
2
= 1
Check the amplitudes of the sine and
cosine signals.
r9
Encoder Simulation
Freq Too High
The computed equivalent encoder
output frequency exceeds the upper
limit for this signal, which is 4 MHz.
Check the parameters used for setting
up the equivalent encoder output.
If using a sine encoder, check the
ENCOUTRES parameter settings.
t1
Power Stage Over-
Temperature
The temperature on the power stage
has exceeded the preset limit.
Check if the ambient temperature
exceeds the drive specification.
Otherwise contact technical support.
t2 Power Module
Over-Temperature
The temperature inside the
integrated power module has
exceeded the preset limit.
Check if the ambient temperature
exceeds the drive specification.
Otherwise contact technical support.
t3 Control Board
Over-Temperature
The temperature on the control
stage has exceeded the preset limit.
Check if the ambient temperature
exceeds the drive specification.
Otherwise contact technical support.
u Under-Voltage
The bus voltage is below the
minimum value.
Check that the main AC voltage supply
is connected to the drive and is
switched on.
The under-voltage limit can be read
with the UVTHRESH command.
