Lenze E82ZAFCC001 System Bus (CAN) Function Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFCC001 is a System Bus (CAN) communication function module engineered for Lenze 8200 Vector frequency inverters, including the E82EV series. Designed as a direct plug-in module for the inverter's dedicated Function Interface (FIF) slot, this device receives internal auxiliary power directly from the host drive controller without requiring external power supplies. Compliant with the ISO 11898 standard, it enables high-speed communication across drive networks using both standard CANopen fieldbus profiles and the proprietary Lenze System Bus protocol.
Fieldbus wiring is established through a removable, pluggable screw terminal block providing connection points for CANL, CANH, and CAN_GND lines. Commissioning a replacement unit requires setting the integrated hardware DIP switches located directly on the module, which determine both the node address (ranging from 1 to 63) and the operational transmission speed between 10 kbit/s and 500 kbit/s. Because network operation relies on exact node identification and baud rate alignment, technicians must ensure the replacement DIP switch positions match the failed unit prior to inserting it into the drive's FIF slot.
Real-time operational feedback is provided via front-panel RUN and ERR status LEDs, which signal bus activity, pre-operational states, warning limits, or bus-off conditions. Further diagnostic insight can be extracted through drive parameter C0359 using Lenze Global Drive Control (GDC) software or a connected XT E82ZBC keypad. Initial troubleshooting steps should verify cable termination with 120 Ohm resistors, proper shield grounding, correct DIP switch configuration, and firm seating of the module header. If internal hardware faults occur, ABC Industrial Parts provides tested replacement units and repair options to help restore production lines efficiently.

Programming and Configuration
Configuring the Lenze E82ZAFCC001 involves both hardware setup and drive parameterization. Basic network identity is established via on-board DIP switches, which define the node address from 1 to 63 and select one of seven supported transmission speeds (10, 20, 50, 100, 125, 250, or 500 kbit/s). This hardware configuration allows fast setup directly at the machine without pre-programming tools.
For full system integration and online diagnostics, the module operates in conjunction with Lenze Global Drive Control (GDC) software or the local XT E82ZBC keypad. Drive parameter C0359 provides system bus diagnostic information, allowing technicians to verify communication states, monitor receive and transmit channels, and adjust monitoring times for transmit Process Data Objects (PDOs).
Communication and System Integration
The E82ZAFCC001 module brings standardized CANopen and Lenze System Bus connectivity to the 8200 Vector drive family in accordance with ISO 11898. It allows multi-drive synchronization, master-slave communication in automated production lines, and remote drive parameterization from PLC automation systems.
Physical bus connections are completed using a pluggable screw terminal block with dedicated terminals for CANL, CANH, and CAN_GND. Up to 63 nodes can participate on a single bus segment, provided that appropriate EMC shielding precautions are followed and 120 Ohm termination resistors are installed at both physical ends of the CAN network.
Diagnostics and Status Indication
The front panel features two status LEDs—RUN (Green) and ERR (Red)—that deliver immediate visual diagnostics. A solid green light indicates normal bus operation, while a blinking green light signals a pre-operational or initializing state. A red LED indicates a bus error, warning limit detection, or a Bus-Off state, with continuous red light highlighting serious hardware faults or unrecoverable communication failures.
Advanced diagnostic monitoring is available online through Lenze Global Drive Control (GDC) or via the drive's diagnostic parameters. In particular, diagnostic code C0359 aids in isolating communication timeouts on individual CAN channels or detecting buffer overruns before they interrupt machine operation.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN / RUN | Green - Solid or Blinking | Solid green indicates normal operational bus state; blinking indicates pre-operational or initializing state. |
| CAN-ERR / ERR | Red - Solid or Flashing | Red LED indicates bus error, warning limit reached, or Bus-Off state. Continuous light indicates hardware fault or severe error. |
Replacement and Spare Part Considerations
When replacing a Lenze E82ZAFCC001 communication module in an 8200 Vector inverter, ensure that power to the frequency inverter is turned off before plugging the module into or removing it from the Function Interface (FIF) slot. Hardware configuration switches must be transferred identically from the original module to the replacement to ensure the new module assumes the correct node address (1-63) and baud rate (10-500 kbit/s) on the CAN network.
Field wiring must be transferred to the replacement module's pluggable screw terminal, ensuring CANL, CANH, and CAN_GND conductors are correctly placed and the cable shield is grounded according to EMC guidelines. If communication errors such as CE0 or CE2 persist after setting switches and verifying network termination resistors (120 Ohm), ABC Industrial Parts can assist with tested replacement modules or repair services to restore reliable operation.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | Communication Error 0 (System Bus / CAN-In1) | Communication failure or telegram timeout on CAN System bus channel 1. | Bus interruption, incorrect baud rate, wrong node address, missing termination resistor, or module fault. | Check CAN wiring, shield grounding, termination resistors (120 Ohm), DIP switch settings, and module insertion. If fault persists on known-good bus, replace module. |
| CE1 | Communication Error 1 (System Bus / CAN-In2) | Communication error or monitoring timeout on CAN System bus channel 2. | Master failed to transmit PDOs within configured monitoring time (time-out). | Verify master transmit rate and cycle time settings; check fieldbus connection. |
| CE2 | Communication Error 2 (CAN Bus Off) | CAN controller reached Bus-Off error state due to excessive transmission/reception errors. | Severe noise interference, bad shielding, mismatched baud rates, or hardware failure on module. | Check shielding, EMC precautions, termination resistors. If hardware fault is indicated, replace E82ZAFCC001 module. |
| CE3 | Communication Error 3 (System Bus / CAN-In3) | Telegram monitoring time elapsed on CAN channel 3. | Interrupted message transmission from CAN master/peer. | Check network master status and cable connection. |
| CE4 | Communication Warning / Fault (CAN FIFO Overflow) | Internal CAN receive buffer overflow. | Excessive bus load or drive processing overload. | Reduce CAN bus baud rate or optimize transmit task timings. |
