Lenze 13034749 Digital Control Board – 8200 Vector Series
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13034749 Digital Control Board serves as the main processing and control logic board for Lenze 8200 vector series frequency inverters. Functioning as the central intelligence of the drive, this board executes core control algorithms, manages physical interlocks, and routes diagnostic signals for variable speed motor control applications. Equipped with internal non-volatile EEPROM memory, the unit retains up to four independent parameter profiles without relying on battery backup. Dual modular expansion headers on the board accept Function Interface (FIF) and Automation Interface (AIF) option modules to expand functional and communication capabilities.
Replacing a 13034749 board requires careful management of communication option modules and parameter sets to achieve proper machine operation. The board interface connects to fieldbus expansion modules such as the E82ZAFCC010 CANopen module, E82ZAFPC001 PROFIBUS adapter, or LECOM RS232/RS485 modules. Because a replacement board is not plug-and-run, configuration parameter sets must be uploaded and restored using Lenze Global Drive Control (GDC) software or the Keypad XT (E82ZBC001) operator unit. Technicians can rely on ABC Industrial Parts to source fully tested replacement boards that keep legacy drive installations operational without full system redesigns.
Onboard diagnostic LEDs provide immediate visual feedback regarding drive status and active operating conditions. A green status LED indicates whether the drive controller is inhibited or active, while a red status LED alerts operators to active warnings or TRIP fault conditions. Detailed fault tracking is accessible through registers C0168 and C0170 via the Keypad XT or GDC real-time monitoring. In cases where both LEDs remain off despite verified control power supply voltage, or when internal microcontroller errors such as code H05 or unrecoverable EEPROM errors such as code EER occur, field repair is not possible. A tested exchange board or repaired unit from ABC Industrial Parts offers a direct path back to full production.

Programming and Configuration
Programming and parameter administration for the Lenze 13034749 digital control board is carried out using Lenze Global Drive Control (GDC) software or the portable Keypad XT (E82ZBC001). The board features internal non-volatile EEPROM memory capable of holding up to four complete parameter profiles. This multi-profile capacity enables versatile drive setups and straightforward backup options across identical machine setups.
When commissioning a spare or replacement board, parameter sets can be rapidly uploaded from a saved file using GDC software or cloned directly from a Keypad XT panel that has stored the donor drive configuration. If parameter corruption occurs or a clean setup is required, restoring factory default settings is executed via register C0002, re-establishing base operational values prior to reloading machine-specific configuration profiles.
Communication and System Integration
The 13034749 main processing board integrates into wider industrial control networks using modular expansion architecture. It incorporates two specialized headers: one Automation Interface (AIF) slot and one Function Interface (FIF) slot. These slots accommodate modular plug-in cards that define the drive interface to supervisory controllers and fieldbus networks.
Supported communication interfaces include the E82ZAFCC010 CANopen module, the E82ZAFPC001 PROFIBUS-DP module, and LECOM RS232/RS485 adapters. These options permit direct integration into automated lines across material handling, packaging machinery, textile processing, and automotive assembly operations. When replacing the digital board, existing AIF and FIF modules must be transferred and seated firmly to ensure unbroken network connectivity and proper bus termination.
Diagnostics and Status Indication
The Lenze 13034749 digital board features dual integrated LEDs that communicate immediate operating and fault states. Diagnostic observation is supplemented by accessing fault memory registers C0168 and C0170 using the Keypad XT module or observing live system parameters in Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Blinking / Solid | Blinking: Drive ready for operation / controller inhibited. Solid ON: Controller enabled / output active. |
| Red LED | Red - Blinking / Solid | Blinking or Solid ON: Fault / TRIP active or warning state present. |
| Both LEDs Off | None - Off | No control supply voltage present, or internal board power supply hardware failure. Unserviceable if supply voltage is verified correct. |
Replacement and Spare Part Considerations
Replacing a faulty Lenze 13034749 control board is an effective strategy for maintaining legacy 8200 vector inverters that have been discontinued. Because the board houses critical control routines and application configurations, installing a replacement unit requires restoring the motor and drive parameters to ensure correct operational behavior.
Before removing a defective board, parameter profiles should be saved to PC via Global Drive Control (GDC) or uploaded into a Keypad XT unit if the board remains powered and responsive. When fitting the replacement 13034749 board, ensure all plug-in AIF and FIF modules are correctly seated. If internal memory corruption occurs (indicated by EEPROM fault code EER) or board hardware fails (code H05 or unlit LEDs with valid supply voltage), board-level repair is not feasible, and replacing the digital board is required to restore drive operation.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit | Short circuit on output phases or excessive capacitive ground current. | Short circuit in motor cable, motor winding fault, or power stage failure. | Check motor and wiring for short circuits; check power module. If fault persists disconnected, replace drive/board. |
| OC5 | I x t Overload | Inverter load exceeds Ixt limit. | Frequent acceleration peaks, motor overloaded, incorrect motor parameters. | Check mechanical load, motor size, acceleration time settings. |
| OU | Overvoltage | DC bus voltage exceeds upper limit. | Braking energy too high, deceleration time too short, main supply voltage too high. | Extend deceleration time, fit braking resistor / chopper, check mains voltage. |
| LU | Undervoltage | DC bus voltage fallen below threshold. | Mains voltage supply failed or supply voltage drop under load. | Check mains voltage supply and line fuses. |
| OH | Heatsink Overtemperature | Heatsink temperature exceeds allowed operating threshold. | Cooling fan failed, clogged heatsink fins, ambient temperature too high. | Clean heatsink fins, ensure adequate ventilation, inspect fan operation. |
| OH4 | Motor Overtemperature (PTC) | Motor thermistor sensor triggered overtemperature fault. | Motor thermal overload, thermistor cable broken or disconnected. | Allow motor to cool, check thermal protection connections and load. |
| CE0 | Communication Error AIF | Communication interruption between digital board and AIF module. | Loose module connection, defective module, or bus cable rupture. | Check seating of AIF module, fieldbus connection and bus termination. |
| EER | EEPROM Fault | Internal EEPROM memory read/write failure on digital board. | Corrupted non-volatile memory or hardware fault on control board. | Reload factory default settings (C0002). If error persists, replace digital board — internal hardware failure. |
| H05 | Internal Hardware Error | Board-level microcontroller or internal system communication fault. | Internal electronic fault on main control board. | Internal board hardware error — field repair not possible; replace digital board or complete drive. |
