51 fault codes documented
No Error Message Displayed
This condition indicates that no specific error message is currently displayed on the CLM01.3-M control panel. This may occur if a diagnostic status request (Status 53) is made when no active fault exists, or if a previously active fault has been cleared.
System Failure
This error code indicates a general system failure within the CLM01.3-M control. It suggests an issue with the fundamental operation of the control unit, which could be electrical or related to missing essential data.
Invalid Input
This error occurs when an invalid value is stored in a CLM01.3-M parameter, exceeding its defined minimum or maximum limits. The invalid data is typically indicated by an asterisk (*) on the display, and the error message appears on the first line.
Emergency Stop
This error signifies that the Emergency Stop circuit has been activated, interrupting the +24 Vdc signal to the CLM01.3-M's Emergency Stop input (connector X3, pin 3). This immediately halts machine operation to ensure safety.
Invalid Mode!
This error occurs when conflicting mode selection inputs are active simultaneously, specifically when Parameter Mode (+24 Vdc to X3, pin 1) is selected while Automatic Mode (+24 Vdc to X3, pin 2) is also active in the CLM01.3-M.
Axis 1 Not Homed
This error indicates that Axis 1 of the CLM01.3-M has not completed its homing procedure, which is a mandatory step before operating in Automatic mode. The system cannot perform absolute positioning without a defined home reference.
Not Home Position
This error occurs if Automatic mode is selected for Axis 1, but the axis is not currently at its designated home position. This indicates that the system's position reference for Axis 1 is lost or the axis has moved from home after a homing cycle.
Drive Not Ready
This error condition occurs when Automatic mode is selected, but the Axis #1 Drive Ready input (CLM01.3-M connector X3, pin 6) is not receiving the required +24 Vdc signal. This indicates the servo amplifier for Axis 1 is not in a ready state.
Marker Pulse 1?
This error occurs if the marker pulse of the Axis 1 encoder is detected too close (closer than 1/16 revolution) to the homing switch cam. This can lead to unreliable homing operations or incorrect home position detection for Axis 1.
No Marker Pulse!
This error occurs if the marker pulse from the Axis 1 encoder is not detected within one full rotation during the homing cycle, or if a continuous marker pulse signal is present. This indicates a problem with the marker pulse feedback for Axis 1.
Min Travel Lmt 1
This error occurs in Automatic Mode for Axis 1 if the commanded position is smaller than the value configured in Parameter 11 (Minimum Travel Limit A1). The system detects an attempt to move Axis 1 beyond its defined minimum operational boundary.
Max Travel Lmt 1
This error occurs in Automatic Mode for Axis 1 if the commanded position is greater than the value configured in Parameter 12 (Maximum Travel Limit A1). The system detects an attempt to move Axis 1 beyond its defined maximum operational boundary.
Maximum Stroke
This error occurs in Automatic mode if the maximum stroke value defined in Parameter 15 (Immediate Stop) is exceeded. This typically happens when Axis 1 travels beyond its allowed stroke limit, often during an Immediate Stop sequence, indicating an overtravel condition.
Immediate Stop
This error occurs when the +24 Vdc signal is applied to the CLM01.3-M's Immediate Stop input (connector X3, pin 5). This input is designed to command an immediate halt to machine operation for safety purposes.
Invalid Block #
This error indicates that a jump or branch command within the CLM01.3-M user program is attempting to direct program execution to a block number greater than 999, which is outside the valid range for program blocks.
Invalid Prg Cmd
This error occurs when the CLM01.3-M user program encounters an unrecognized or syntactically incorrect program command. The command is not part of the valid instruction set defined for the CLM01.3-M.
BCD Input
This error occurs if a BCD (Binary Coded Decimal) command is encountered in the CLM01.3-M user program, but the auxiliary inputs designated for BCD operation are not configured or wired to interpret data in BCD format.
JSR Nesting
This error indicates that the nesting depth of subroutines (JSR commands) in the CLM01.3-M user program has exceeded the maximum allowable limit of 127. Excessive nesting can lead to stack overflow or unpredictable program behavior.
EOS Cmd Missing
The "EOS Command Missing" error occurs when the CLM01.3-M user program fails to execute an EOS (End of Synchronization) command where required, specifically at the end of a flying cutoff cycle. This error also triggers if LMD, LML, or LMR commands are encountered before EOS.
RTS Nesting
This nesting error occurs when an RTS (Return from Subroutine) command is encountered in the CLM01.3-M program without a preceding, matching JSR (Jump to Subroutine) command. This indicates an illogical program flow, as the system attempts to return from a subroutine that was never called.
Invalid Axis Nr.
This error occurs if the CLM01.3-M user program contains a command that references an invalid axis number. This could be an axis that does not exist, is not configured, or is outside the permissible range for axis numbering.
Drive Runaway A2
This "Drive Runaway Axis 2" error indicates a conflict between the direction of the Axis 2 encoder feedback and the commanded polarity of Axis 2. This means the drive is trying to move in one direction, but the encoder reports movement in the opposite, or there's a misconfiguration in feedback/command polarity.
Excess Pos Lag A2
This error occurs when Axis 2 is commanded to a position but the Axis 2 servo system exhibits excessive position lag, meaning it is not following the commanded trajectory accurately. This often points to issues with the drive's power, feedback, or tuning.
Abs. Encoder 1
This error occurs if the absolute encoder for Axis 1 is not properly connected, or if data transmission between the encoder and the CLM01.3-M is interrupted or corrupted. This prevents the system from obtaining an absolute position reference for Axis 1.
Abs. Range 1
This error occurs if Axis 1 travels beyond the maximum number of turns (revolutions) supported by its absolute encoder. This indicates an overtravel condition relative to the encoder's multi-turn counting capability.
Abs Encoder 2
This error occurs if the absolute encoder for Axis 2 is not properly connected, or if data transmission between the encoder and the CLM01.3-M is interrupted or corrupted. This prevents the system from obtaining an absolute position reference for Axis 2.
Abs. Range 2
This error occurs if Axis 2 travels beyond the maximum number of turns (revolutions) supported by its absolute encoder. This indicates an overtravel condition relative to the encoder's multi-turn counting capability, preventing accurate position tracking.
RS Break-Error
This error occurs if the optional IDS board is enabled via Parameter 80 (Serial Interface) but the CLM01.3-M fails to detect a physical connection to the IDS board. This indicates a communication or hardware issue with the IDS board.
Division By Zero
This error indicates an internal software fault within the CLM01.3-M, specifically a division by zero operation during internal calculations. This is a critical error and typically points to a firmware issue or corrupted operational data.
Parameters Lost
This error occurs when the CLM01.3-M's back-up battery, responsible for retaining parameters when power is off, is disconnected or has low voltage. This results in the loss of critical configuration parameters, indicated by asterisks (*) on the display.
Program Lost
This error occurs when the CLM01.3-M's back-up battery, which stores the user program when power is off, is disconnected or has low voltage. This leads to the loss of the application program, requiring re-entry or restoration.
FeedAngle Loss 2
This error occurs if the feed angle auxiliary input, configured in Parameter 54 (Monitoring A2), drops to a low signal state while Axis 2 is in motion. This indicates a loss of feedback critical for synchronized operation or process control.
Marker Pulse 2?
This error occurs if the marker pulse from the Axis 2 encoder is detected too close (closer than 1/16 revolution) to the homing switch cam. This can lead to unreliable homing operations or incorrect home position detection for Axis 2.
No Marker Pulse2
This error occurs if the marker pulse from the Axis 2 encoder is not detected within one full rotation during the Axis 2 homing cycle, or if a continuous marker pulse signal is present. This points to a problem with the marker pulse feedback for Axis 2.
Min Travel Lmt 2
This error occurs in Automatic mode for Axis 2 if the commanded position is smaller than the value configured in Parameter 51 (Minimum Travel Limit A2). The system detects an attempt to move Axis 2 beyond its defined minimum operational boundary.
Max Travel Lmt 2
This error occurs in Automatic mode for Axis 2 if the commanded position is greater than the value configured in Parameter 52 (Maximum Travel Limit A2). The system detects an attempt to move Axis 2 beyond its defined maximum operational boundary.
Axis 2 Not Homed
This error occurs if the user program attempts to execute an absolute position command for Axis 2, but Axis 2 has not yet been homed. Homing is essential to establish a precise absolute position reference.
Drive Runaway A1
This "Drive Runaway Axis 1" error indicates a conflict between the direction of the Axis 1 encoder feedback and the commanded polarity of Axis 1. This means the drive is trying to move in one direction, but the encoder reports movement in the opposite, or there's a misconfiguration in feedback/command polarity.
Synchr. Diff. A2
The "Synchronization Difference A2" error occurs when the position difference between Axis 1 and Axis 2 motors exceeds the value configured in Parameter 40 (Synchr. Diff. A2). This indicates a loss of coordinated motion between the synchronized axes.
Index Length
This error occurs when the system attempts to switch from Manual to Automatic mode, but the amount of material that has passed under the measuring wheel is greater than the configured part length. This implies a discrepancy in material tracking during a mode transition.
Battery Is Low
This condition occurs when the lithium back-up battery, located on the MOK 11 card, which is responsible for retaining CLM01.3-M memory (programs, parameters, counter status) during power OFF, falls below its minimum voltage level.
RS Block # Wrong
This serial communication error occurs when the program command transmitted to the CLM01.3-M contains an invalid program block number. The block number sent via serial interface must be between 000 and 999.
RS Format Error
This serial communication error indicates that the transmitted information contains more characters than allowed, or a Carriage Return/Line Feed (CR/LF) sequence is missing at the end of the transmission. This signifies an incorrect overall message structure.
RS Block Data Error
This serial communication error indicates that the format of the program command data transmitted to the CLM01.3-M was incorrect. This is a general error related to the structure or content within a program block, rather than just the overall message length or termination.
RS Checksum Error
This serial communication error occurs when the checksum calculated by the CLM01.3-M from received data does not match the checksum transmitted by the sending device. This indicates data corruption during transmission, if checksum is enabled.
Invalid Mode
This serial communication error occurs when an attempt is made to transmit parameter information without first setting the CLM01.3-M to Parameter mode. It also triggers if specific LM Control Commands like "I CLO $DF" are transmitted in Automatic mode.
RS Para # Wrong
This serial communication error indicates that the parameter number transmitted to the CLM01.3-M is invalid. The parameter number must be provided in a two-digit format and fall within the range of 00 to 99.
RS Para # Too Big
This serial communication error is a specific instance of "RS Para # Wrong", indicating that the parameter number transmitted to the CLM01.3-M is greater than 99. The CLM01.3-M expects parameter numbers to be in the range of 00 to 99.
RS Stat # Wrong
This serial communication error indicates that an incorrect format was used to request status information from the CLM01.3-M. This could be due to an invalid status number or a general formatting issue with the status request command string.
Invalid Status #
This serial communication error occurs if the status number being transmitted to the CLM01.3-M is invalid, meaning it is not included in the list of defined status numbers in Chapter 7, Serial Interface. The CLM01.3-M cannot process requests for non-existent status numbers.
Invalid Prg Command
This serial communication error indicates that the program command transmitted to the CLM01.3-M is invalid. The command is not recognized as part of the valid instruction set documented in Chapter 5, Programming.
