Troubleshooting CDHD
42 Servotronix
Display Fault Name Description Action Required
j Velocity Over-
Speed Exceeded
Actual velocity exceeded 1.2 times
the velocity limit. The velocity limit
is set using VLIM.
Check that VLIM is set to match the
application requirements. Using
velocity loop tuning, check for
excessive overshoot.
n STO Fault The STO signal is not connected. Check that the STO connector (P1) is
wired correctly.
n1 Regen Over-
Current
The preset current limit for regen
current has been exceeded.
Increase the value of the regen
resistor.
o Over-Voltage The bus voltage exceeded the
maximum value.
Check whether a regen resistor is
required for the application.
o15
Plus 15V Out of
Range
The in15 V supply is out of
range.
The drive probably needs repair.
Contact technical support.
o-15 Minus 15V Out of
Range
The internal -15 V supply is out of
range.
The drive probably needs repair.
Contact technical support.
P Over-Current
Over current at the drive output has
been detected.
The drive allows this fault to occur
up to 3 times in succession. After
3 faults, the drive forces a delay of
1 minute before it can be reenabled.
Check for a short circuit on the motor
connection.
Check for excessive overshoot in the
current loop.
r10 Sine Feedback
Communication Fail
Communication problem between
the drive and the EnDat encoder.
Check that the data and clock signals
to the EnDat encoder are connected
properly. The cable must be shielded.
r14
Sine Encoder
Quadrature Fault
Mismatch between calculated and
actual encoder quadrature
information.
Check the feedback device wiring.
Check that the correct encoder type
(MENCTYPE) is selected.
r15
Sin/Cos Calibration
Invalid
The sine/cosine calibration
parameters are out of range. This
fault is related to resolver and sine
encoder feedback.
Re-execute the sine/cosine calibration
process.
r16
Feedback 5V Over-
Current
The current supplied by the drive on
the 5V primary encoder supply has
exceeded the preset current limit.
The drive allows this fault to occur
up to 3 times in succession. After
3 faults, the drive forces a delay of
1 minute before it can be reenabled.
The CDHD can source a maximum
current of 250 mA to the primary
encoder.
Check for a short-circuit at the
encoder.
Check if the encoder is drawing more
than the current limit.
r17 Secondary
Feedback Index
Break
Secondary encoder index line not
connected.
Check whether the drive is configured
for working with the index signal on
the secondary encoder, and check if
the index signal is connected.
r18 Secondary
Feedback A/B Line
Break
One of the secondary feedback
signals is not connected.
Check that all signals from the
secondary encoder are properly
connected to the drive.
r19
Secondary
Feedback 5V Over-
Current
The preset current limit for current
supplied by the drive on the 5 V
secondary encoder supply has been
exceeded.
The CDHD can source a maximum
current of 250 mA to the secondary
encoder.
Check for a short-circuit at the
encoder.
Check if the encoder is drawing more
than the current limit.
r20 Feedback
Communication
Error
Communication with the feedback
device did not initialize correctly.
Check that the feedback device is
wired correctly.
Check that the correct encoder type
(MENCTYPE) is selected.
r21 Sanyo Encoder
Operational Fault
Communication with the Sanyo
Denki feedback device did not
initialize correctly.
Check that the feedback device is
wired correctly.
Check that the correct encoder type
(MENCTYPE) is selected.
