23 IPM Thermal Protection Fault
24 Excess Velocity Error
25 Sensor not assigned
26 User-specified Velocity Fault
27 Axis Not Homed
28 Motor Parameter Error
29 Encoder Output Frequency
Exceeded
30 Encoder Communication Fault
31 Encoder Data
32 Sine/Cosine Encoder Fre-
quency Limit Exceeded
U l t i m a S V
Probable Cause
The internal filter protecting the
drive from overheating has
tripped
Velocity error limit was
exceeded
Homing or registration motion
was attempted without a sensor
assigned
User specified velocity level
was exceeded
Absolute positioning was
attempted without homing
Parameter loaded from smart
encoder or received from SER-
COS controller is incompatible
with the drive
Encoder output frequency
exceeds the maximum user
specified value. This only
applies when the encoder out-
put is synthesized by the drive.
Communication was not estab-
lished with an intelligent
encoder
Encoder data is corrupted
Maximum frequency of the
sine/cosine circuitry has been
exceeded

Corrective Action
• Reduce acceleration rates
• Reduce duty cycle (ON/OFF)
of commanded motion
• Increase time permitted for
motion
• Use larger Ultra3000 and
motor
• Check tuning
• Increase time or size of allow-
able error
• Reduce acceleration
• Check tuning
Assign a sensor to a digital
input
Increase to a less restrictive
setting
Verify homing sequence
• Select a different motor
through the SERCOS control-
ler
• Select a different motor.
• Increase the encoder output
maximum frequency parame-
ter
• Decrease the encoder interpo-
lation parameter
• Increase the encoder output
divider parameter
• Verify motor selection
• Verify the motor supports
automatic identification
• Verify motor encoder wiring
Replace the motor/encoder
• Decrease velocity
• Use encoder with lower reso-
lution (before interpolation)
