Specific Fault Code Examples & Troubleshooting (Codes 10-20)
Within the Lenze drive fault code range of 10-20, several codes require specific attention. Code 10, the “GOTO Error,” indicates a flawed unconditional jump instruction within a user-defined macro program; review the macro logic for correct addressing. Code 11, “Stack Overflow,” suggests excessive data processing, potentially due to recursive function calls or large data structures – optimize the program to reduce memory usage.
Other codes in this range often relate to communication or parameter settings. Troubleshooting involves verifying cable connections, checking parameter configurations against the application requirements, and ensuring proper termination. Examining the drive’s operational history and recent parameter changes can pinpoint the root cause.
Referencing the Lenze drive fault code PDF is crucial, as it provides detailed explanations and recommended actions for each code. Systematic troubleshooting, starting with the simplest solutions (cable checks, parameter verification) before delving into complex software issues, is recommended.
Detailed Explanation of Code 10: GOTO Error
Lenze drive fault Code 10, designated as a “GOTO Error,” signifies a critical flaw within a user-programmed macro. Specifically, it indicates an invalid or unreachable destination specified by a GOTO instruction. This means the program attempts to jump to a line number that either doesn’t exist or is inaccessible due to program structure.
The root cause typically lies in incorrect line numbering within the macro, a misspelled label, or a logical error preventing the program from reaching the intended GOTO target. Thoroughly review the macro program listing, paying close attention to all GOTO statements and their corresponding labels.
Troubleshooting involves verifying the accuracy of line numbers, ensuring labels are correctly spelled and positioned, and checking for any conditional statements that might bypass the GOTO instruction. The Lenze fault code PDF emphasizes careful macro program analysis to resolve this error, preventing unpredictable drive behavior.
Analyzing Code 11: Stack Overflow
Lenze drive fault Code 11, identified as a “Stack Overflow,” indicates a critical error in macro program execution. This occurs when a subroutine or function calls itself recursively too many times, exceeding the allocated memory space known as the “stack.” Essentially, the program runs out of memory to store return addresses and local variables.
The primary cause is typically infinite recursion – a subroutine calling itself without a proper exit condition. This can also happen with excessively deep nesting of subroutine calls. The Lenze fault code PDF highlights the importance of carefully designing macro programs to avoid such scenarios.
Troubleshooting involves reviewing the macro code for recursive calls, ensuring each subroutine has a clear exit path. Reducing the depth of subroutine nesting can also help. Analyzing the program logic to identify potential infinite loops is crucial. Correcting the code to prevent excessive stack usage will resolve this fault.
Interpreting Code 22: Serial Timeout & Drive Reaction
Lenze drive fault Code 22 signifies a “Serial Timeout,” indicating a communication failure between the drive and its controller. This means the drive didn’t receive expected data within a predefined timeframe during serial communication. The Lenze fault code PDF details how this impacts operation.
The drive’s reaction to this timeout is configurable via selection options. Option 0 disables the watchdog timer, meaning no action is taken. However, Option 1 initiates a “Controller Inhibit,” halting drive operation to prevent potentially unsafe behavior. This is a safety feature.
Troubleshooting involves verifying the serial communication link – checking cable connections, baud rate settings, and addressing. Confirm the controller is transmitting data correctly and that no communication interference exists. If the timeout persists, investigate potential controller issues or a faulty serial interface on the drive itself. Proper configuration of the timeout settings is also vital.
Troubleshooting Torque and Angle Related Faults (e.g., Low Torque/Angle)
Lenze drive fault codes related to low torque or angle indicate issues with the motor’s ability to deliver expected performance. The Lenze fault code PDF identifies these as critical for maintaining process accuracy and preventing damage; These faults often stem from mechanical load problems, motor inefficiencies, or incorrect drive parameters.
Troubleshooting begins with verifying the mechanical system – checking for obstructions, excessive friction, or overloaded conditions. Inspect the motor itself for winding faults or bearing issues. Within the drive parameters, confirm correct torque limits, acceleration/deceleration settings, and encoder feedback configurations.
The PDF highlights “mum level” settings related to torque and angle; these thresholds trigger faults when exceeded. Ensure these values are appropriately set for the application. Investigate potential issues with the encoder feedback signal, as inaccurate angle data can lead to torque-related errors. A systematic approach, guided by the PDF, is crucial for effective diagnosis.
Decoding Information Result Codes (4517, 4519)
Lenze drive fault code PDFs detail “Information Result Codes” which, while not critical faults, provide valuable diagnostic insights; Codes 4517 and 4519 are prime examples, offering clues about process performance and potential issues. Code 4517, “Tighten- Tightening time limit exceeded,” suggests the drive couldn’t achieve the desired torque within the programmed timeframe, potentially indicating mechanical problems or incorrect parameters.
Code 4519, “Slip Off / Lost target was reached,” signifies the motor lost synchronization with the commanded position. This could be due to excessive load, insufficient torque, or issues with the encoder feedback system. These codes don’t immediately halt operation but warn of developing problems.
The Lenze documentation emphasizes that these codes should prompt investigation. Reviewing the application’s mechanical setup, drive parameters (acceleration, torque limits), and encoder functionality is crucial. Ignoring these informational results can lead to more severe faults and downtime. The PDF serves as a key to understanding these nuanced messages.
