19 fault codes documented
Beginning Address Fault in MDT
This fault indicates that the data contained within the parameter 'Length of the MDT' (IDN S-0-0009) is invalid. This can prevent proper communication and operation of the DDS 2.1 drive.
Error During Position Initialization
This error occurs when the DDS 2.1 drive encounters a problem calculating the motor encoder's position during its initialization process. This prevents the drive from establishing proper position control.
No Absolute Encoder Present
This fault is triggered when the DDS 2.1 drive attempts to execute the procedure command 'Set Absolute Measuring' (IDN P-O-0012) but does not detect an absolute encoder on the connected motor. This indicates a mismatch between the commanded function and the motor's feedback device.
Drive Into Positive Stop Procedure Command Error
This error indicates a problem during the execution of the procedure command 'Drive Into Positive Stop' (IDN S-0-0149), causing the DDS 2.1 drive to shut down. This prevents the drive from performing its commanded controlled stop function.
Overload Shutdown
A Class 1 Diagnostic indicating a shutdown error due to the DDS 2.1 drive or motor operating beyond its specified continuous load limits. The drive decelerates to zero speed and subsequently shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Amplifier Over Temperature Shutdown
A Class 1 Diagnostic indicating a shutdown error because the power stage section of the DDS 2.1 drive has reached an excessively high temperature. This shutdown typically follows an 'Amplifier Over Temperature Warning' (diagnostic '50') that persisted for more than 30 seconds. The drive immediately decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Power Supply Phase Error
A Class 1 Diagnostic indicating an issue with one or more phases of the incoming three-phase AC power supply to the DDS 2.1 drive. This typically means a phase loss or significant imbalance, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Excessive Position Deviation
A Class 1 Diagnostic indicating that the actual position of the motor significantly deviates from the commanded target position by more than an allowed tolerance, leading to a drive shutdown. This implies the motor is not following its commanded profile accurately or has encountered an obstruction. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Communication Error
A Class 1 Diagnostic indicating a critical failure in the SERCOS communication between the master controller and the DDS 2.1 drive. This error can manifest as various issues like MST/MDT failures, invalid communication phase transitions, or address conflicts, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Travel Limit Value Exceeded
A Class 1 Diagnostic indicating that the motor or driven axis has reached or exceeded its software or hardware travel limits. This safety mechanism prevents mechanical damage by initiating an immediate drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Product Specific Error
A Class 1 Diagnostic indicating a product-specific internal error within the DDS 2.1 drive that does not fall under other defined Class 1 categories. This generic fault code points to a critical issue requiring a drive shutdown to prevent further damage. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Motor Over Temperature Shutdown
A Class 1 Diagnostic indicating a shutdown error because the motor has reached an excessively high temperature. The DDS 2.1 drive is notified via a thermal resistor in the motor windings. This shutdown typically follows a 'Motor Over Temperature Warning' (diagnostic '51') that persisted for more than 30 seconds. The drive immediately enters a shutdown mode according to parameter P-O-0007, Error Reaction. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Cooling Error Shutdown
A Class 1 Diagnostic indicating a critical fault related to the DDS 2.1 drive's cooling system, leading to an immediate shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel. This error signifies a failure in maintaining the drive's operating temperature within safe limits, distinct from simple over-temperature which allows a 30-second warning.
Control Voltage Error
A Class 1 Diagnostic indicating an issue with the DDS 2.1 drive's internal control voltage supply. This often means that one or more internal low-voltage DC supplies (e.g., 24V, 5V) required for the control electronics are out of tolerance or absent, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Feedback Error
A Class 1 Diagnostic indicating a problem with the motor's position or velocity feedback device connected to the DDS 2.1 drive. This could include issues with the encoder signal, sensor wiring, or the feedback device itself, leading to a loss of control and drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Commutation Error
A Class 1 Diagnostic indicating that the DDS 2.1 drive cannot correctly determine or maintain the motor's magnetic pole position for proper commutation. This critical error results in a loss of motor control and drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Overcurrent Error
A Class 1 Diagnostic indicating that the current drawn by the motor exceeded the instantaneous peak current limit of the DDS 2.1 drive. This is often a sudden and severe event, leading to immediate drive shutdown to protect the power components. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Overvoltage Error
A Class 1 Diagnostic indicating that the DC bus voltage within the DDS 2.1 drive has exceeded its maximum permissible limit. This usually occurs during deceleration or due to an issue with the mains power supply, leading to a drive shutdown to protect internal components. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
Undervoltage Error
A Class 1 Diagnostic indicating that the DC bus voltage within the DDS 2.1 drive has fallen below its minimum permissible operating threshold. This typically occurs due to an issue with the incoming mains power supply, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.
