Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFB001 System-CAN Communication Module is a dedicated interface card engineered to integrate Lenze 8200 vector and 8200 motec series frequency inverters into centralized automation networks. Slotting directly into the host inverter's Function-In-Function (FIF) slot, this communication module draws power directly from the drive, eliminating the need for external control voltage wiring. Designed for line topology fieldbus structures, the module enables rapid peer-to-peer drive coordination and integration into higher-level CANopen networks across material handling, packaging, automotive manufacturing, and textile processing systems.
Connecting the replacement E82ZAFB001 module to the fieldbus network is handled through a detachable plug-in screw terminal block providing connection points for CAN-High, CAN-Low, and CAN-Ground signal lines. The module supports selectable communication baud rates ranging from 10 kbit/s to 1000 kbit/s using both the Lenze System Bus protocol and standardized CANopen fieldbus profiles. Onboard DIP switches allow field technicians to configure node addresses, transmission speeds, and active 120 Ohm bus termination without needing specialized programming software during hardware installation. When deeper configuration or diagnostic monitoring is required, parameters can be modified using Lenze Global Drive Control (GDC) software or a Lenze Keypad XT / E82ZBC handheld terminal. When commissioning a replacement unit, engineering teams can rely on ABC Industrial Parts for pre-tested spare modules and technical advice on matching physical DIP switch settings.
Real-time operational status and network diagnostics are provided through front-panel CAN-RUN and CAN-ERR LED indicators. The green CAN-RUN LED indicates active operational status or initialization states, while the red CAN-ERR LED illuminates during bus-off conditions, warning thresholds, or internal communication faults. Further diagnostic monitoring can be carried out through host drive parameters C0359, C0587, and C0588, which log specific fault codes such as CE0 for internal RAM or EEPROM memory errors, CE1 for bus-off errors, and CE3 for process data timeout. First-line troubleshooting should start with verifying module seating in the FIF slot, inspecting terminal block connections and polarity, and checking DIP switch settings. If persistent memory errors like code CE0 indicate internal component damage, hardware repair or an exchange unit from ABC Industrial Parts offers a fast path to restore operational availability.

Programming and Configuration
Hardware configuration on the Lenze E82ZAFB001 is executed using onboard DIP switch blocks located directly on the module body. These DIP switches allow technicians to select node ID addresses, configure bus transmission speeds between 10 kbit/s and 1000 kbit/s, and activate or deactivate the integrated 120 Ohm bus termination resistor. Because basic network settings are configured via hardware switches, physical replacement of the module can be completed without requiring specialized software tools prior to initial power-up.
Advanced drive parameterization and continuous process monitoring can be performed using Lenze Global Drive Control (GDC) software connected through the host frequency inverter. Alternatively, local access is available via the Lenze Keypad XT or E82ZBC handheld terminal. Specific CAN network diagnostic parameters, including C0359, C0587, and C0588, provide real-time visibility into operational states, error counters, and communication performance directly from the host drive interface.
Communication and System Integration
The E82ZAFB001 communication module supports both the proprietary Lenze System Bus protocol and standardized CANopen fieldbus profiles. This dual-protocol capability allows 8200 vector and 8200 motec frequency inverters to participate in fast peer-to-peer speed synchronization across multi-drive conveyor lines or interface directly with centralized PLCs managing complex machinery.
Physical network connection is provided via a plug-in screw terminal block with dedicated terminals for CAN-High (CAN-H), CAN-Low (CAN-L), and CAN-Ground (CAN-GND). Designed for line topology networks, the module includes an onboard 120 Ohm terminating resistor that can be activated via DIP switch at physical end nodes, eliminating the need for external terminating resistors on the network.
Diagnostics and Status Indication
Visual operational feedback is delivered directly through two front-panel status LEDs. The green CAN-RUN LED indicates whether the module is operational, pre-operational, or uninitialized on the CAN bus network. The red CAN-ERR LED highlights bus warnings, communication error threshold breaches, or complete bus-off conditions that require attention.
Internal controller diagnostics are accessible via host inverter drive parameters C0359, C0587, and C0588. These parameter codes allow maintenance teams to assess communication error counters, monitor process data objects, and quickly pinpoint whether error states originate from network wiring issues or internal hardware faults.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Solid / Flashing / Off | Green ON: Module operational and active on CAN bus. Flashing: Pre-operational or initializing state. OFF: Module powered off or not initialized. |
| CAN-ERR | Red - Solid / Flashing / Off | Red ON: Bus-Off state or severe hardware fault. Red Flashing: Communication error limit reached (CAN warning threshold exceeded). OFF: Normal operation without bus errors. |
Replacement and Spare Part Considerations
When replacing an E82ZAFB001 module on an existing Lenze 8200 vector or 8200 motec inverter, technicians must ensure that the replacement module's DIP switch configuration matches the settings of the removed unit. Node address selection, baud rate settings, and the 120 Ohm termination resistor toggle must be aligned prior to inserting the module into the host inverter's Function-In-Function (FIF) interface slot.
Because the module draws operating power directly through the host drive's FIF interface slot, no external power supply wiring is required during swap-out. Proper physical seating within the slot is essential to maintain internal electrical connection; incomplete seating can trigger fault code CE0.
Although the Lenze 8200 vector inverter series and associated E82ZAF modules are discontinued legacy components, maintaining spare E82ZAFB001 modules is essential for extending the operational lifecycle of installed manufacturing machinery. For long-term system modernization, Lenze recommends the i550 cabinet frequency inverter series as a direct successor featuring integrated CANopen communication capabilities.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | CAN Memory Error / Communication Fault | Internal communication failure or RAM/EEPROM corruption within the CAN function module. | Internal hardware failure on E82ZAFB001 module or incorrect seated connection in FIF slot. | Reseat module in FIF slot and power cycle. If fault persists, the internal module hardware is damaged and requires replacement. |
| CE1 | CAN Bus-Off State | CAN controller transitioned to Bus-Off state due to excessive transmit/receive error count. | Incorrect baud rate setting on DIP switch, reversed CAN-H/CAN-L signals, missing or duplicate bus termination, damaged cable shield, extreme EMC interference. | Check CAN line polarity (CAN-H, CAN-L), verify 120 Ohm termination at both end nodes, check DIP switch baud rate, verify grounding and shielding. |
| CE2 | CAN Warning Limit Reached | Error counter of the CAN controller exceeded the warning threshold value. | Poor signal quality, sporadic loose connections, improper shielding, excessive cable length for selected baud rate. | Inspect CAN cabling, check terminal connections, verify maximum cable length versus set baud rate. |
| CE3 | CAN Time-Out (Process Data) | No cyclic process data object (PDO) received within the programmed monitoring time interval. | CAN master stopped transmitting, master program fault, cable broken, node address mismatch. | Check status of master controller, verify node address setting on DIP switch, check CAN network traffic. |
| CE4 | CAN Bus Master Failure | Communication telegrams from designated bus master missing. | Master unit offline, power failure at master, master bus interface disabled. | Check power and operating state of CAN master station. |
