Lenze E82ZAFC001 System-CAN Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFC001 is a System-CAN communication module engineered for integration into Lenze 8200 vector frequency inverters, 8200 motec drives, and Drive PLC systems. Operating as a direct plug-in function module, this device provides a differential CAN interface for networking field devices across material handling, packaging, logistics, textile manufacturing, and automotive assembly applications. Internal operating power of 5 V DC at 110 mA is supplied directly through the host drive's function module slot, eliminating the need for external power connections.
Establishing networking via an ISO 11898 differential CAN physical interface, the unit supports both System-CAN and standardized CANopen protocols at configurable transmission speeds ranging from 10 kbit/s to 1000 kbit/s. Up to 63 bus nodes can be configured directly on the module using hardware DIP switches for address selection and baud rate configuration, while an integrated switchable 120 Ohm bus termination resistor simplifies field wiring. Putting a replacement module into service requires setting the DIP switches on the spare unit to match the original hardware configuration, isolating power from the inverter, and seating the module securely into the interface slot. Keypad parameter access using the E82ZBC module or software tools such as Global Drive Control (GDC) and L-force Engineer allow quick verification of drive parameters, with ABC Industrial Parts available to assist with sourcing tested replacement hardware.
Real-time operational monitoring is provided by front-panel status LEDs, including CAN-RUN and CAN-ERR indicators that show pre-operational states, active communication, warning limits, and Bus Off conditions. Complementing visual indications, host drive diagnostic parameters such as C0359 and C0361 report detailed bus activity, buffer status, and communication timeouts. Standard error conditions include CAN bus errors (CE0), CAN Bus Off states (CE1), buffer overflows (CE2), parameter channel timeouts (CE3), and function module failure faults (F_CAN). If communication cannot be established after checking wiring, termination, and DIP switch settings, internal hardware faults or damaged connector pins may require drive slot inspection or replacement through ABC Industrial Parts to restore machine uptime.

Programming and Configuration
Configuration of the Lenze E82ZAFC001 communication module is performed primarily through hardware DIP switches located directly on the unit. These switches enable tool-free setting of the CAN node address for up to 63 network nodes and selection of transmission speeds from 10 kbit/s up to 1000 kbit/s. Because node identification and baud rate are defined at the physical module level, basic network integration can be completed without requiring immediate software access.
For advanced parameterization, drive commissioning, and network diagnostics, the module interfaces with Lenze engineering software, including Global Drive Control (GDC) and L-force Engineer. Operators can also access drive parameters and network monitoring data using the plug-in Lenze E82ZBC Keypad connected to the host drive. These tools allow detailed adjustment of process data objects (PDOs) and service data objects (SDOs), enabling refined peer-to-peer drive control and host controller integration.
Communication and System Integration
The E82ZAFC001 provides an ISO 11898 differential CAN interface designed for high-speed network communication in industrial automation environments. Operating on both System-CAN and standardized CANopen communication protocols, the module enables peer-to-peer data exchange between drive controllers, packaging machinery, conveyor lines, and higher-level controllers.
To ensure signal integrity across the CAN network, the module features an integrated, switchable 120 Ohm bus termination resistor. This built-in termination eliminates the need for external terminating components at the physical ends of the bus line. The module supports multi-node topologies containing up to 63 bus devices, making it adaptable for distributed speed and motion control applications across extensive production machinery.
Diagnostics and Status Indication
Front-panel visual diagnostics on the E82ZAFC001 are delivered through two dual-state LED indicators: CAN-RUN and CAN-ERR. The green CAN-RUN LED indicates pre-operational status when blinking and solid operational status when active CAN communication is present. The red CAN-ERR LED alerts maintenance personnel to warning limit thresholds, frame errors, or persistent Bus Off states that interrupt network control.
In addition to physical LEDs, the host drive maintains internal diagnostic parameters—such as codes C0359 and C0361—that record real-time communication status, buffer states, and error statistics. These diagnostic codes can be monitored online through Global Drive Control (GDC) or displayed directly on the E82ZBC Keypad for rapid troubleshooting of bus disruptions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Blinking / Solid | Blinks in pre-operational state; Solid ON when operational or CAN communication is active |
| CAN-ERR | Red - Blinking / Solid | Blinks when warning limit or frame error occurs; Solid ON during Bus Off state or critical hardware fault |
Replacement and Spare Part Considerations
When replacing a Lenze E82ZAFC001 module, electrical safety and hardware matching are primary considerations. Power to the host 8200 vector, 8200 motec, or Drive PLC unit must be completely disconnected before removing or inserting the communication module. Before installing the spare unit, match the DIP switch positions for node address and baud rate selection exactly to those on the original module.
The E82ZAFC001 is powered directly through the host drive slot at 5 V DC and draws 110 mA. During installation, visually inspect the slot connector pins to ensure they are free of bends or damage before seating the module firmly. Once secured and powered, verify that the CAN-RUN LED illuminates and that no CAN error codes appear on the host drive display.
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 CAN bus | System-CAN communication warning limit exceeded or timeout during operation. | Bus interruption, wiring error, wrong baud rate, missing bus termination, excessive EMC interference. | Check CAN bus cable, wiring polarities, terminating resistors at both ends of the bus line, and check set baud rate across all nodes. |
| CE1 | CAN Bus Off error | Module went into Bus Off state due to persistent transmit/receive errors. | Duplicate node address, incorrect baud rate, disconnected bus cable, extreme noise. | Verify node addresses are unique, check baud rate settings on DIP switches, verify grounding and shield connections. |
| CE2 | CAN buffer overflow / telegram error | Internal receive or transmit buffer overflow on CAN module interface. | High bus load, master sending telegrams faster than slave can process. | Reduce bus load, increase cyclic time settings for PDO transmittal. |
| CE3 | CAN parameter channel timeout | Timeout during SDO/parameter transfer over System-CAN. | Master device timed out waiting for parameter response from drive. | Check CAN connection and response timeout setting in controller/master. |
| F_CAN | Function module failure / CAN hardware error | Host drive cannot communicate with the E82ZAFC001 function module. | Module not correctly seated in interface slot, bent connector pins, or internal hardware damage. | Re-seat module firmly into slot with power disconnected. If fault persists, replace module. |
