Lenze E82ZAFCC – 8200 Series CAN/System Bus Function Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFCC is a CAN and System Bus function module designed for Lenze 8200 vector and 8200 motec frequency inverters. Operating as a plug-in communication module, the unit mounts directly into the host drive's Function Module Interface (FIF) slot and receives its 5 V DC supply voltage internally from the drive. This communication module expands host drive capabilities, enabling real-time speed and position synchronization across distributed drives as well as centralized PLC control over fieldbus networks.
Connecting the E82ZAFCC to an active network is managed via a pluggable screw terminal strip featuring connections for CAN-H, CAN-L, and CAN-GND. Supporting communication speeds between 10 kbit/s and 500 kbit/s, the module implements both the standard CANopen DS301 profile and the high-speed Lenze System Bus protocol using CAN 2.0A. Commissioning a replacement unit requires configuring the onboard hardware DIP switches to match the original node ID and baud rate settings. Drive parameters and communication profiles can be transferred or verified using Lenze Global Drive Control software version 4.0 or higher or an optional Keypad XT unit, with technical assistance available through ABC Industrial Parts when re-establishing fieldbus integration.
Diagnostic feedback is provided on the front cover through two visual indicators: the green CAN RUN LED and the red CAN ERR LED. These LEDs display operational modes, communication warnings, or severe bus-off states, while system bus parameters C0359, C0361, and C0363 offer deeper diagnostic monitoring via software or keypad. Initial troubleshooting should verify CAN-H and CAN-L polarity, 120 Ohm bus line termination, supply stability, and DIP switch positions. If communication errors persist or the unit enters an unrecoverable Bus-Off state due to internal hardware failure, ABC Industrial Parts can supply a replacement or tested exchange module to restore machine operation quickly.

Programming and Configuration
Software setup for the Lenze E82ZAFCC is handled using Lenze Global Drive Control (GDC) software version 4.0 or above, or locally using a Keypad XT (E82ZBC) module. Communication parameters, including response monitoring times for CAN process data objects, are adjusted under parameter registers C0357/1 through C0357/3.
Hardware configuration simplifies commissioning through integrated DIP switches located on the module. These switches allow technicians to set node addresses and baud rates without requiring software tools, enabling fast physical replacements during maintenance.
Communication and System Integration
The E82ZAFCC provides dual fieldbus communication capabilities, supporting both open CANopen (DS301 profile) and the Lenze System Bus (CAN 2.0A). Operating at selectable speeds from 10 kbit/s up to 500 kbit/s, it integrates 8200 vector and 8200 motec inverters into higher-level controller architectures or synchronized drive networks.
Physical wiring connects via a pluggable screw terminal block accommodating CAN-H, CAN-L, and CAN-GND lines. Correct network operation requires standard 120 Ohm bus termination resistors fitted at both line ends, maintaining a total line resistance of 60 Ohms across the bus.
Diagnostics and Status Indication
Status monitoring is available directly on the module's front cover via visual LED indicators. Additional diagnostic analysis can be performed through Lenze Global Drive Control software or Keypad XT by inspecting system bus parameters C0359, C0361, and C0363, or by using a external CANbus analyzer tool.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN RUN | Green - Solid / Blinking / Off | Off: Pre-operational / stop state. On: Operational status, regular CAN communication active. Blinking: Pre-operational state. |
| CAN ERR | Red - Solid / Flashing / Off | Off: No CAN communication error. Blinking: CAN warning limit reached or telegram error. On: CAN Bus-Off state or hardware communication failure. |
Replacement and Spare Part Considerations
Replacing an existing E82ZAFCC module requires plugging the new unit into the host drive's Function Module Interface (FIF) slot. The pluggable screw terminal strip enables quick hardware swaps without disturbing existing network cables.
Before restoring power, ensure the onboard DIP switches on the spare unit are aligned with the target node address and baud rate settings. Verify that process data monitoring registers match the application requirements in Lenze GDC software to ensure seamless fieldbus synchronization.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | CAN bus communication fault (Time-out) | Communication failure on the Lenze System Bus (CAN). No process data received within configured monitoring time. | Bus cable broken or disconnected, incorrect baud rate, incorrect node address, slave not power-supplied, terminating resistors missing. | Check bus cable connections and shielding, verify matching baud rate on all nodes, verify DIP switch settings, check 120 Ohm termination resistors at line ends. |
| CE1 | CAN-In1 monitoring time exceeded | Process data object CAN-In1 was not received within the response time limit set in C0357/1. | Master controller stopped transmitting CAN-In1 PDO, network overload, master cycle time too slow. | Check master controller run status, check PLC cycle time and PDO transmission timing, check CAN connection. |
| CE2 | CAN-In2 monitoring time exceeded | Process data object CAN-In2 was not received within the response time limit set in C0357/2. | Master controller failed to transmit CAN-In2 frame, fieldbus interruption. | Verify host PLC process data configuration and cyclic transmission settings. |
| CE3 | CAN-In3 monitoring time exceeded | Process data object CAN-In3 was not received within the response time limit set in C0357/3. | Transmission interruption for process data object CAN-In3. | Check transmitter node configuration and cabling. |
| CE4 | System bus (CAN) Bus-Off state | The CAN controller went into Bus-Off state due to excessive transmission or reception error counters. | Extremely high electromagnetic interference (EMC), inverted signal lines (CAN-H and CAN-L swapped), missing or duplicate termination resistors, mismatch in baud rate. | Check CAN-H and CAN-L wire polarity, ensure correct grounding/shielding, check termination resistance (60 Ohm total across bus line), reset fault on inverter. If persistent with correct wiring, internal hardware failure — replace the module. |
