Allen-Bradley PowerFlex 40

This fault indicates an issue with a remote auxiliary input. This input is typically configured to trigger a fault condition when active or inactive, depending on the setup. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault signifies a loss of incoming AC line power or a significant low voltage condition on the AC input. It indicates the drive's inability to maintain operation due to insufficient input power.

This fault is triggered when the incoming AC line voltage drops below the drive's acceptable operating range. This can be caused by a sustained low voltage condition or a momentary power sag. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault occurs when the incoming AC line experiences high voltage or transient conditions, or when the motor regenerates energy back into the drive (e.g., during rapid deceleration). This can cause the DC bus voltage to exceed safe limits. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault indicates that the motor has stalled or is experiencing an excessive load, causing the drive output current to exceed the current limit set by parameter A089 [Current Limit]. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

An excessive motor load exists, causing the drive output current to surpass the motor overload current limit defined by parameter P033 [Motor OL Current]. This protects the motor from thermal damage. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

The drive's heatsink temperature has exceeded its safe operating limit, indicating insufficient cooling. This can be caused by obstructions, high ambient temperatures, or a malfunctioning cooling fan. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault indicates an excessive current condition detected by the drive's hardware. Potential causes include excessive motor load, incorrect DC boost settings, or excessively high DC brake voltage.

This fault detects a current path from the motor or drive output wiring to ground. This can be caused by damaged motor insulation or faulty wiring between the drive and the motor.

This fault occurs when an analog input, configured to fault upon signal loss, loses its expected input signal. This means the drive is no longer receiving a valid reference from the analog source (e.g., 0-10V or 4-20mA). This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault indicates that the drive has exhausted its configured number of automatic restart attempts (parameter A092 [Auto Rstrt Tries]) after a previous fault. The underlying cause of the initial fault must be addressed before the drive can restart.

This fault indicates a grounded condition on motor phase U (output terminal U) between the drive and the motor. This usually points to insulation breakdown in the motor winding or the connecting cable.

This fault indicates a grounded condition on motor phase V (output terminal V) between the drive and the motor. This usually points to insulation breakdown in the motor winding or the connecting cable.

This fault indicates a grounded condition on motor phase W (output terminal W) between the drive and the motor. This usually points to insulation breakdown in the motor winding or the connecting cable.

This fault detects a short circuit condition between motor phases U and V at the drive output. This implies an insulation failure within the motor windings or a direct short in the cabling connecting the drive to the motor.

This fault detects a short circuit condition between motor phases U and W at the drive output. This implies an insulation failure within the motor windings or a direct short in the cabling connecting the drive to the motor.

This fault detects a short circuit condition between motor phases V and W at the drive output. This implies an insulation failure within the motor windings or a direct short in the cabling connecting the drive to the motor.

This fault indicates that the drive was commanded to write default parameter values to its EEPROM memory. This action resets all user-configured parameters to their factory default settings.

This fault is triggered by the drive's software when the output current exceeds a set limit. It suggests that the load requirements are too high or that parameter A098 [SW Current Trip] is set too low for the application. This is an Auto-Reset/Run type fault configurable with parameters A092 and A093.

This fault indicates that the drive itself is operating beyond its continuous current rating, typically due to an excessive motor load or an acceleration time that is too short.

This is a general fault related to the drive's internal power unit. It indicates an internal hardware issue within the drive that cannot be resolved by simple troubleshooting.

This fault occurs when communication is lost with the drive over the configured network. This could be due to physical disconnection, network configuration issues, or a problem with the communication adapter.

This fault signifies that the autotune function for Sensorless Vector Control (SVC) was either intentionally cancelled by the user or failed to complete successfully. This might prevent optimal motor control.

This fault indicates a loss of communication with the drive's control source, possibly due to an adapter disconnection, wiring issue, or a communication timeout. This fault's action (fault, stop, continue) can be configured by A105.

This fault indicates an inconsistency or corruption in the drive's parameter memory (EEPROM). This can happen due to unexpected power cycling or internal memory issues, requiring a restoration of default settings.

This fault indicates an internal failure of the drive's I/O board. This is a critical internal hardware issue that typically requires replacement of the drive.
