Lenze E82ZAFD Function Module CANopen
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFD is a plug-in CANopen function module engineered for Lenze 8200 vector and 8200 motec frequency inverters. Designed to fit directly into the standardized Function Interface (FIF) slot of the drive, this communication module establishes fieldbus connectivity between the host inverter and centralized automation networks. Power for the module is supplied internally at 24 V DC through the drive interface slot, eliminating the need for external power supplies or additional panel space.
Physical bus connection is made via a 5-pole pluggable screw terminal. Operating under the standard CANopen CiA DS301 profile, the module supports Process Data Objects (PDO) for fast cyclic control and Service Data Objects (SDO) for parameter access across the bus. When commissioning a spare module, network configuration is performed using front-accessible hardware DIP switches that define node addressing from 1 to 63 and transmission speeds from 10 to 1000 kbit/s. Drive parameters can be fine-tuned or verified using Lenze Global Drive Control (GDC) software or an optional E82ZBC Keypad Module, with ABC Industrial Parts available to assist with replacement verification and unit sourcing.
Real-time operational monitoring is facilitated by two front-panel status LEDs: a green CAN-RUN indicator displaying operational states and a red CAN-ERR indicator signaling network errors, bus-off conditions, or guarding faults. Further diagnostics are accessible through host drive parameters C0091 and C0150 through C0154, displaying error conditions such as CAN timeouts (CE0), bus-off faults (CE1), receive buffer overflows (CE2), and node guarding events (CE3). Basic troubleshooting includes checking fieldbus wiring, verifying the 120 ohm line termination resistors, and checking DIP switch address settings. If internal communication error CE4 occurs, power down the drive and re-seat the module in the FIF slot; persistent internal hardware faults are not field-serviceable, making unit replacement or tested exchange units through ABC Industrial Parts the ideal path back to operation.

Programming and Configuration
Parameterization of the Lenze E82ZAFD communication module is performed either using Lenze Global Drive Control (GDC) software connected to the host drive or through the plug-in Lenze E82ZBC Keypad Module. Hardware network settings, including node addressing (1 through 63) and baud rate selection (10 to 1000 kbit/s), are configured directly using manual DIP switches located on the front of the module.
In addition to manual DIP switch settings, host inverter parameters C0091 and C0150 through C0154 enable access to network state monitoring and error tracking. Advanced network response times, such as Node Guarding and Heartbeat monitoring intervals, are adjusted via parameters C0352 and C0353. Alignment between these parameter settings and the central CANopen PLC configuration ensures consistent control system performance.
Communication and System Integration
The E82ZAFD module integrates Lenze 8200 vector and 8200 motec variable frequency drives into CANopen networks complying with the CiA DS301 profile. Equipped with a 5-pole pluggable screw terminal, the module provides a standard physical connection interface for fieldbus topologies across factory automation systems.
Full support for Process Data Objects (PDO) enables high-speed cyclic exchange of drive control words, setpoints, and operational status feedback. Service Data Objects (SDO) permit complete access to drive parameters over the network. With configurable transmission speeds up to 1000 kbit/s and addressable node capacity up to 63 subscribers, the module enables efficient distributed drive control.
Diagnostics and Status Indication
Visual operational feedback is provided via two status LEDs on the front of the module. The green CAN-RUN LED indicates CANopen node status across Operational, Pre-Operational, and Stopped states through solid and flashing conditions. The red CAN-ERR LED illuminates or flashes to indicate bus errors, bus-off conditions, or guarding time-outs.
Detailed troubleshooting is supported through host drive diagnostic parameters C0091 and C0150–C0154. In the event of a fault condition, the module can also transmit standard CANopen emergency messages across the fieldbus to notify the master controller.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Solid / Flashing | Indicates CANopen operational status (Operational, Pre-Operational, Stopped) |
| CAN-ERR | Red - Solid / Flashing | Indicates CANopen bus error state (Bus Off, Error Warning, Node Guarding / Life Time Event) |
Replacement and Spare Part Considerations
Before replacing an E82ZAFD module, disconnect all primary supply power from the host 8200 vector or 8200 motec inverter. Verify that the hardware DIP switches on the new module are positioned to match the Node ID and baud rate settings of the unit being replaced prior to inserting the module into the FIF slot.
Following physical installation, reconnect the 5-pole pluggable terminal block and ensure proper bus termination is present. If the drive reports error CE4 upon power-up, ensure that the module is fully seated in the interface slot and that terminal contacts are clean.
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 0 (CAN Time-out) | Communication failure or time-out on CANopen bus (PDO time-out / bus off). | Bus line disconnected, incorrect wiring, incorrect baud rate, master stopped, terminating resistors missing. | Check CAN cabling and 120 ohm terminating resistors. Verify baud rate setting and host controller status. |
| CE1 | CAN bus-off state | The CAN controller on the module entered the Bus-Off state due to excessive transmission or reception error frames. | Severe EMI/RFI noise, faulty cable shield connection, baud rate mismatch, wrong node ID. | Check grounding and shielding of bus lines. Verify baud rate settings on all node devices. Restart module/inverter. |
| CE2 | CAN receive buffer overflow | Data received faster than the host inverter internal task processing capacity. | Excessive PDO transmission rates or unhandled burst messages on the bus. | Increase PDO transmission cycle time / inhibit time from CANopen master controller. |
| CE3 | CAN Guarding Error / Heartbeat Error | Node guarding or heartbeat monitoring triggered a life fault event. | Master stopped polling node within Guard Time, or heartbeat producer failed. | Verify CANopen master state and configured Node Guarding / Heartbeat parameters (C0352/C0353). |
| CE4 | CAN internal communication error | Internal communication fault between E82ZAFD function module and host inverter CPU. | Bad electrical connection at FIF interface slot, damaged connector pins, internal module hardware failure. | Turn off power, remove and re-seat E82ZAFD module in FIF slot. If error persists, replace E82ZAFD module. |
