CDHD Drive Status
Quick Start Guide 63
Display Light Type Name Description Action Required
r6 Fault 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.
If the feedback type is
Tamagawa, check that the
feedback wiring is correct
r8 Fault 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 Fault 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.
t Steady Warning Over-Temperature The temperature on the power
board and/or on the control
board has exceeded the preset
limit.
Check if the ambient
temperature exceeds the
drive specification. Otherwise
contact technical support.
t1 Fault Power Stage Over-
Temperature The temperature on the power
board has exceeded the preset
limit. Check if the ambient
temperature exceeds the
drive specification. Otherwise
contact technical support.
t2 Fault 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 Fault Control Board
Over-Temperature The temperature on the control
board has exceeded the preset
limit. Check if the ambient
temperature exceeds the
drive specification. Otherwise
contact technical support.
u Flash Fault 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.
u Steady Warning 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.
Verify that the setting of
UVMODE is correct.
Warning Encoder Hall Switch
Not Found
Hall switch not yet detected.
Warning Encoder Index Not
Detected
Index not yet detected.
Warning HIPERFACE
Encoder Resolution
Mismatch
Encoder resolution, as
determined from the detected
HIPERFACE device information,
is different from the current
settings of MENCRES Enter the correct resolution
(MENCRES value).
Warning HIPERFACE Device
Not Supported
The detected HIPERFACE device
is not supported Contact technical support.
