Lenze 13141234 E82ZAFAC – 8200 Vector System Bus CAN Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFAC (part number 13141234) is a System Bus CAN communication function module engineered for Lenze 8200 vector and 8200 motec series frequency inverters. Operating as a plug-in front module, this unit interfaces directly with the inverter base unit through a multi-pin header FIF interface to establish CANopen and Lenze System Bus networking. Physical bus connections are wired via a 5-pole plug-in screw terminal block supporting CAN-High, CAN-Low, CAN-GND, and shielding lines. The module enables drive controllers to exchange real-time process data, parameter sets, and control commands across centralized automation systems in material handling, packaging, automotive manufacturing, and textile processing applications.
Integrating a replacement module into an active network requires matching physical hardware settings before placing the unit into service. Onboard DIP switches allow operators to set node addresses from 1 to 63, select operational baud rates between 10 kbit/s and 500 kbit/s, and activate an integrated 120 Ohm bus termination resistor at physical line ends. Communication parameters and network settings are stored directly in the base inverter memory, simplifying replacement procedures once physical hardware switches are aligned. When replacing a failed communication card, ABC Industrial Parts can provide fully tested hardware units to restore network communications without replacing the main drive assembly.
System diagnostics are accessible on the front panel through two status LEDs. The green CAN-RUN indicator signals pre-operational, reset, or active operational communication states, while the red CAN-ERR indicator alerts operators to warnings, frame errors, or Bus-Off conditions. Advanced diagnostic information, including system bus error registers and fault histories, can be evaluated using Lenze Global Drive Control software or an optional XT EMZ8201BB keypad. Specific diagnostic fault codes such as CE0, CE1, CE2, and CE3 help pinpoint cabling faults, node address conflicts, or network timeouts. When a solid red CAN-ERR LED indicates an unrecoverable internal hardware condition, ABC Industrial Parts offers diagnostic repair and exchange options to return critical machinery to operation.

Programming and Configuration
Hardware configuration for the Lenze E82ZAFAC module is performed using onboard DIP switches located directly on the unit. These switches allow technicians to assign unique node addresses between 1 and 63 and set network transmission speeds from 10 kbit/s up to 500 kbit/s. A dedicated termination DIP switch activates the internal 120 Ohm resistor, eliminating the requirement for external terminating plugs on end-of-line nodes.
Software parameterization and network diagnostic monitoring are supported through Lenze Global Drive Control (GDC) software and the optional Lenze XT EMZ8201BB keypad module. Because operational parameter settings reside inside the memory of the host 8200 vector or 8200 motec inverter, replacing a module requires setting the DIP switches to match the target station profile before inserting the unit.
Communication and System Integration
The Lenze E82ZAFAC system bus module provides fieldbus networking based on CAN layer 2 and CANopen protocols. Operating across baud rates from 10 kbit/s to 500 kbit/s, the module enables deterministic communication and data exchange between frequency inverters and central PLCs or master controllers. Up to 63 nodes can be networked on a single system bus segment.
Network cabling connects directly to the front of the module using a 5-pole plug-in screw terminal block. Terminals are dedicated to CAN-High, CAN-Low, CAN-GND, and shield grounding lines to preserve signal integrity in industrial environments. The rear multi-pin header FIF interface establishes a secure internal connection to the host inverter logic board upon insertion.
Diagnostics and Status Indication
Front-panel visual diagnostics are provided by dual status LEDs labeled CAN-RUN and CAN-ERR. In addition to LED indications, detailed register diagnostics and fault history can be accessed through Lenze Global Drive Control software or via the diagnostic menu on an optional XT EMZ8201BB keypad.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Solid / Flashing / Off | Off: Pre-operational or reset state; Flashing: Pre-operational state; Solid: Operational state with active bus communication. |
| CAN-ERR | Red - Solid / Flashing / Off | Off: No error; Flashing: Warning, Bus-Off warning state, or frame errors; Solid: Bus-Off state or internal module hardware fault. |
Replacement and Spare Part Considerations
Replacing a Lenze E82ZAFAC function module requires matching the DIP switch settings on the replacement card with those of the original unit. Ensure the node address (1–63), baud rate setting (10–500 kbit/s), and internal 120 Ohm termination resistor switch align with the network topology before mounting the module.
Because network settings and process parameters are stored within the base 8200 vector or 8200 motec inverter memory, separate module software flashing is not required during field replacement. After setting the DIP switches and seating the card into the FIF interface header, reattach the 5-pole terminal block and re-apply power to restore communications.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | CAN Time-out / Communication Error 0 | Communication failure on CAN system bus during process data telegram monitoring. | Bus cable disconnected, incorrect baud rate setting, wiring fault, or master station stopped. | Check CAN cabling, verify termination resistor switches, and check baud rate settings and master controller status. |
| CE1 | CAN BUS-OFF | Module entered CAN Bus-Off state due to excessive transmission error counter. | Faulty bus cabling, missing grounding/shielding, duplicate node address, or incorrect baud rate. | Check bus connections and shielding, verify unique DIP switch node addressing, and cycle power or reset CAN error. |
| CE2 | CAN Buffer Overflow | Receive or transmit buffer overflow on system bus interface module. | Excessive bus load or host system sending process data faster than processing rate. | Reduce network bus load, increase transmission intervals, and check network configuration settings. |
| CE3 | CAN Monitoring Fault | Node guarding or heartbeat monitoring timeout. | Master failed to send guarding request within configured time window. | Verify master cycle time, check network connections, and inspect master controller state. |
Frequently Asked Questions
How do I set the node address and baud rate on the Lenze E82ZAFAC module?
Node addresses (1 to 63) and baud rates (10 kbit/s to 500 kbit/s) are configured manually using the DIP switches located on the front panel of the module.
Is an external bus termination resistor needed on a CAN network using the E82ZAFAC?
No external resistor is required if the module is at the end of the line. The E82ZAFAC includes an integrated 120 Ohm bus termination resistor that can be activated via DIP switch.
Which drive series are compatible with the E82ZAFAC communication module?
The module connects to Lenze 8200 vector and Lenze 8200 motec series frequency inverters via an internal multi-pin header FIF interface.
How can diagnostic information and fault codes be read from the module?
Visual feedback is provided by the CAN-RUN and CAN-ERR LEDs. Comprehensive register data and fault logs can be read using Lenze Global Drive Control (GDC) software or an XT EMZ8201BB keypad.
Does replacing an E82ZAFAC module require transferring software programs?
No. Drive parameter and network configurations are saved in the base inverter memory. Matching the DIP switch settings on the new module restores network functionality upon power-up.
