Product Information
The Lenze E82ZAFCC201 is a CAN I/O function module engineered for communication integration within the Lenze 8200 vector and 8200 motec frequency inverter ranges. Operating directly as a plug-in option in the dedicated Function-in-Function (FIF) interface slot, this communication module enables multi-axis drive synchronization and centralized control across industrial drive networks. The unit receives its internal 5 V DC power supply directly through the host inverter FIF slot, eliminating the need for external control voltage wiring.
For network communication and commissioning, the E82ZAFCC201 provides a pluggable screw terminal block supporting both the proprietary Lenze System Bus protocol and standardized CANopen fieldbus communication according to the CiA DS301 profile. Data transmission rates can be selected from 10 kbit/s up to 1000 kbit/s, supporting up to 63 network nodes on a single bus segment with standard 120 Ohm termination resistors at physical network endpoints. Hardware DIP switches on the module allow technicians to manually set node addresses and baud rates without specialized engineering tools, though complete setup and PDO/SDO parameter transfers can also be executed using Lenze Global Drive Control (GDC) software or the Keypad XT (E82ZBC). When deploying a replacement module into an existing installation, ABC Industrial Parts can support maintenance teams with fast access to verified spare components to restore drive communication quickly.
Diagnostic feedback is provided on the front interface via two dedicated status LEDs: CAN RUN (green) and CAN ERR (red), which indicate operational state, pre-operational status, bus warnings, and bus-off fault conditions. In addition, system monitoring can be performed through host drive diagnostic parameters C0361 (CAN state) and C0363 (error counters) on a connected keypad or within GDC software. Common communication interruptions, such as time-out errors (CE0), transmission bus-off states (CE1), object mapping faults (CE2), or buffer overflows (CE4), can generally be resolved by inspecting terminal block wiring, shielding, bus termination, or node settings. If the module triggers an initialization failure code (CE3) or experiences an unresolvable internal hardware fault after verifying slot seating, hardware repair or a tested exchange unit from ABC Industrial Parts offers a direct path to minimizing machine downtime.

Programming and Configuration
Hardware configuration of the Lenze E82ZAFCC201 CAN I/O module can be completed using integrated DIP switches located directly on the unit. These switches allow manual selection of the network node ID and transmission baud rate, allowing maintenance staff to configure basic node parameters without connecting additional software tools or handheld programmers.
For advanced configuration, parameter backup, and detailed process data mapping, the module interacts with Lenze Global Drive Control (GDC) software or the Keypad XT (E82ZBC) attached to the host inverter. Through GDC or keypad interface, engineers can configure Process Data Objects (PDOs) and Service Data Objects (SDOs), adjust transmission cycle times, and manage system bus communication registers across multi-drive configurations.
Communication and System Integration
The E82ZAFCC201 module establishes fieldbus connectivity through a pluggable screw terminal block, enabling drive-to-drive peer-to-peer communication or integration into higher-level PLC automation systems. It supports dual protocol operation, working seamlessly with both the proprietary Lenze System Bus (CAN) protocol and standard CANopen fieldbus structures following the CiA DS301 specification.
Supporting communication speeds ranging from 10 kbit/s to a maximum baud rate of 1000 kbit/s, the module can interconnect up to 63 network nodes on a single bus line. Proper bus operation requires standard 120 Ohm terminating resistors installed at both physical ends of the network segment to maintain signal integrity and prevent data transmission errors across material handling and conveyor installations.
Diagnostics and Status Indication
Visual status monitoring is handled directly on the module faceplate by two distinct LED indicators. The green CAN RUN LED signals operational mode, pre-operational mode, stopped mode, or an uninitialized supply state. The red CAN ERR LED flags fault states, remaining off during normal operation, flashing when reaching warning limits or error passive states, and staying solid on during bus-off conditions or CAN controller hardware faults.
Beyond visual LEDs, technicians can monitor detailed diagnostic data directly on the host drive using parameters C0361 for CAN status and C0363 for internal error counters. These diagnostic registers, accessible via Lenze GDC software or the Keypad XT, enable real-time tracking of message error counts and bus communication performance.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN RUN | Green - Off / Flashing / Single Flash / Solid On | Off: No supply or uninitialized; Flashing: Pre-Operational mode; Single Flash: Stopped mode; Solid On: Operational mode |
| CAN ERR | Red - Off / Flashing / Solid On | Off: No error; Flashing: Warning limit reached or Error passive; Solid On: Bus off state or CAN controller hardware fault |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82ZAFCC201 module, verify that the spare unit is fully seated into the host 8200 vector or 8200 motec inverter FIF slot with power disconnected. Ensure that the DIP switch positions for node address and baud rate on the replacement module are set identically to the original unit prior to reapplying control power.
If custom PDO mappings, specialized communication parameters, or non-default baud settings were previously stored in the host drive parameter memory, verify these settings using Global Drive Control (GDC) software or the Keypad XT module. Ensure external 120 Ohm termination resistors remain correctly placed at network end nodes and that the pluggable screw terminal connector is firmly reconnected.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | CAN-TRX | Communication error during CAN data reception (Time-out on Process Data Object / PDO monitoring) | Bus line interrupted, CAN master failed, incorrectly set baud rate or node address, improper bus termination | Check CAN wiring and shield connections, verify baud rate and node address on DIP switches/parameters, check CAN master operation and terminating resistors |
| CE1 | CAN-TX | CAN message transmission fault / CAN Bus-Off state | Short circuit or open circuit on CAN_H / CAN_L lines, high noise/interference on bus, missing bus termination | Check CAN bus cable, check for 120 Ohm termination resistors at both network ends, ensure proper grounding/shielding |
| CE2 | CAN-OBJ | Systembus CAN object / configuration error | Invalid object mapping or corrupt PDO configuration in parameter set | Verify CAN parameter settings using GDC or Keypad, re-assign valid PDO identifiers |
| CE3 | CAN-INIT | CAN module initialization error | Function module incorrectly seated in FIF slot, hardware communication failure between drive and module | Turn off power, re-seat E82ZAFCC201 module securely in FIF slot. Internal hardware fault - return unit for repair if error persists |
| CE4 | CAN-OVR | CAN receive buffer overflow | Excessive traffic on CAN network, transmission rate too high for drive processing speed | Reduce CAN bus load, optimize PDO transfer cycle time or filter unnecessary CAN messages |
Frequently Asked Questions
How is the Lenze E82ZAFCC201 function module powered?
The module is powered internally with 5 V DC supplied directly from the host Lenze 8200 vector or 8200 motec inverter via the FIF slot interface.
What protocols are supported by the E82ZAFCC201 CAN module?
It supports both the proprietary Lenze System Bus (CAN) protocol for drive-to-drive communication and standardized CANopen fieldbus communication following the CiA DS301 profile.
How are the node address and baud rate configured on the E82ZAFCC201?
Node address and baud rate can be configured manually via on-board hardware DIP switches without software tools, or digitally using Lenze Global Drive Control (GDC) software or a Keypad XT (E82ZBC).
What do the CAN RUN and CAN ERR LEDs indicate?
