INDICATION
POSSIBLE CAUSE
CORRECTIVE ACTION
PWR Base FLT
Excessive current usage.
Disconnect motor leads from control and retry test. If problem persists,
contact your local Baldor office.
Excessive noise on resolver lines.
Check resolver connections.
Separate resolver leads from power wiring.
Cross resolver wires and power leads at 90
°
.
Electrically isolate resolver from motor.
Install optional Isolated resolver Feedback expansion board.
Electrical noise from external DC
coils.
Install reverse biased diodes across all external DC relay coils as shown in
the Opto Output circuit examples of this manual. See Electrical Noise
Considerations in Section 5 of this manual.
Electrical noise from external AC
coils.
Install RC snubbers on all external AC coils. See Electrical Noise
Considerations in Section 5 of this manual.
Excessive load.
Correct motor load.
Verify proper sizing of control and motor.
Excessive power in DB circuit.
Verify proper Ohm and Watt parameters of DC Injection Braking.
Increase decel time.
Add optional DB resistor.
Feedback
Resolver failure.
Check resolver to motor coupling (align or replace if needed).
Verify correct wiring.
Unknown Fault
Fault occurred but cleared before its
source could be identified.
Check AC line for high frequency noise.
Check input switch connections and switching noise.
User Fault Text
Fault detected by custom software.
Refer to custom software fault list.
