This is a prewarning indicating that the motor temperature has reached an elevated level, approaching its thermal limits. Continued operation at this temperature could lead to motor damage or a full shutdown.

The commanded target position exceeds the configured software or hardware travel limits for the axis. This can lead to unexpected motion or an inability to reach the desired position.

The axis has not been referenced or 'homed' since power-up or a previous reset. This prevents accurate absolute positioning and certain motion commands.

The feedrate override parameter S-0-0108 is set to zero, effectively stopping all motion. This prevents any velocity or position commands from being executed.

The torque limit parameter is set to zero, preventing the motor from generating any torque. This causes the drive to be unable to move or hold position.

The drive controller was commanded to execute a process block that does not exist or has not been programmed into its memory. This prevents the execution of the requested motion sequence.

The drive controller or associated power electronics are experiencing an elevated load, approaching their thermal capacity. Continued operation at this level could lead to a device shutdown.

The commanded velocity exceeds the maximum allowable velocity configured for the axis. This prevents the drive from executing the command and can indicate an incorrect motion profile or parameter setting.

The commanded target position or the internal position calculation has exceeded the numerical range supported by the drive controller. This can happen with extremely large position values or incorrect scaling.

The holding brake is unable to generate sufficient torque to hold the load, or the drive detects that the brake torque is below the expected threshold. This can lead to uncontrolled motion of the load.

The current flowing through the drive's power section has exceeded its maximum safe limit. This is a critical warning that indicates an immediate risk of damage to the drive or motor.

The actual or commanded position has exceeded the configured positive software travel limit. This can lead to the machine reaching its mechanical hard stop or unexpected motion.

The actual or commanded position has exceeded the configured negative software travel limit. This can lead to the machine reaching its mechanical hard stop or unexpected motion.

An Emergency Stop condition has been detected, causing an immediate and controlled shutdown of the drive and potentially the entire machine. This is a critical safety response.

The actual torque or force developed by the motor has reached its configured limit. This warning indicates that the motor is operating at its maximum allowed output for torque/force.

The motor current has reached its configured limit, indicating that the drive is trying to deliver maximum current but may not be able to achieve the commanded torque or speed due to load conditions.

The positive hardware travel limit switch has been activated, indicating that the axis has reached its maximum physical travel in the positive direction. This typically results in a controlled stop.

The negative hardware travel limit switch has been activated, indicating that the axis has reached its maximum physical travel in the negative direction. This typically results in a controlled stop.

The motor is experiencing an overload condition, and its current has reached the configured limit. This indicates that the motor is being driven beyond its continuous operating capacity, posing a risk of overheating.

The drive controller or associated power electronics are experiencing an overload condition, and the internal current has reached the configured limit. This indicates that the device is being operated beyond its continuous capacity, posing a risk of overheating.

The drive system is not in a ready state to accept commands or operate the motor. This can be due to pending errors, incomplete initialization, or unfulfilled safety conditions.

The commanded torque or force value has reached the maximum configured limit, indicating that the drive is restricting the output to prevent exceeding its operational boundaries or protecting the mechanical system.

The configured cam shaft profile or parameters are invalid, incomplete, or corrupted. This prevents the drive from executing cam-based motion profiles.

The MultiMediaCard (MMC) containing drive parameters, firmware, or application data has been removed or is no longer detected. This prevents the drive from loading necessary configuration and operating.

The drive was commanded to switch to an operating mode (e.g., velocity, position, torque) that has not been properly initialized or configured. This prevents the drive from entering the requested mode.

The drive has detected a change in the connected motor type compared to the previously stored configuration. This requires a parameter adjustment to ensure correct motor control.

The drive is indicating that it is loading default parameter values. This can happen during initial setup, after a parameter reset, or if configuration data is lost.

The drive encountered an error during the initialization process of its digital input/output (DIO) modules. This prevents the proper function of discrete control signals.

The analog signal amplitude from encoder 1 is outside the expected range, indicating a problem with the encoder, its cabling, or the drive's input circuit. This affects position and velocity feedback accuracy.

The automatic commutation fine adjustment procedure failed to validate the motor's commutation angle. This can lead to inefficient motor operation or control instability.

An error has occurred with the external 24VDC power supply connected to terminal X10 of the drive, which typically provides control power to the drive or external I/O.

The difference between the expected and actual position feedback values is excessively large. This indicates a significant discrepancy in position tracking, potentially due to a feedback error or mechanical issue.

The difference between the commanded position and the actual position of the axis is too large, indicating that the drive cannot follow the commanded trajectory accurately. This is often related to tuning or mechanical issues.
