![]() ![]() ![]() This error only applies to firmware revisions prior to 1.10. The motor position exceeds +/- 2047 revolutions from the home position (applies only to systems with absolute feedback). Increase machine cycle size or reduce velocity profile. The velocity command or feedback exceeds half the machine cycle length per millisecond (applies only when the machine cycle position rollover is enabled). E50 Duplicate node detected in SERCOS ringįigure 2: Allen Bradley Rockwell Servo Drive failure, Rockwell Servo Drive Repair.E39 Servo communication error or startup failure.E38 SERCOS ring parameters are not enabled.E36 Detected that the power supply temperature is high or the board is overheated.E33 Absolute position exceeds position roller.E32 Exceeding the frequency limit of Sine/Cosine encoder.E31 Encoder data cannot be found (encoder is damaged).E30 The motor encoder and servo cannot communicate.E29 Encoder failure or model matching error.E28 Comparing the smart encoder with the SERCOS controller, it is found that the parameters are not compatible.E27 When it is not the zero position, the servo tries to perform an absolute position movement. ![]() E25 Change or pre-action error, sensor failure.E24 The speed is unstable or exceeds the limit.E19 Position error fault of motion axis.E18 Overspeed, the speed exceeds the defined 125%.E16 The software setting exceeds the allowable value.E14 SERCOS or DeviceNet communication interrupted.E13 The zero position remains unchanged or restricted.E12 Zero position error, or outside the zero position range.E10 Bus overvoltage, high input voltage or bad detection circuit.E9 The busbar is undervoltage, input phase is missing or the detection circuit is broken.E8 Motor feedback failure or encoder failure.E6 The positive and negative travel errors, the detection circuit is broken, or the travel switch is broken.E5 The imp module is faulty, and there is a short circuit in the power output part.E3 Absolute position error (only used in absolute encoder feedback).E2 Error on speed limit(only appears in the control mode of mechanical roller position enable).E1 The position movement exceeds the limited range during work (only used in absolute encoders).Ab Rockwell Ultra3000 servo drive failure alarm: We have listed the common faults and repair methods of Ultra3000 servo drives, if you need to replace the equipment, we provide Allen Bradley Rockwell Servo Drive.įigure 1: Common Faults and Repair Methods of Allen Bradley Rockwell Servo DriveĢ.
