Product Information
The Lenze 00472935, model designation E82ZAFSC010, is a dedicated System Bus CAN communication module engineered for Lenze 8200 Vector frequency inverters. Operating directly within the drive's integrated Function In Field (FIF) slot and powered by an internal 5 V DC supply, this module allows host inverters to communicate across decentralized automation architectures. Physical network connections are established via a 4-pin pluggable spring-clamp terminal block that accommodates CAN-Low, CAN-High, ground, and cable shield lines.
The E82ZAFSC010 supports high-speed data exchange using the Lenze System Bus protocol and CANopen profiles across networks up to 63 nodes, with configurable transmission rates from 10 kbit/s to 500 kbit/s. Commissioning a replacement unit requires no external software programming tools for basic operational setup, as network node addresses and baud rates are selected directly through onboard DIP switches S1 through S8. When installing a spare unit, matching the DIP switch positions from the original hardware ensures proper bus recognition. If assistance is required during installation or network integration, ABC Industrial Parts can support maintenance teams with replacement units and technical guidance.
Diagnostic information is provided on the front panel via two status LEDs. A green LED (LED1) indicates operational System Bus activity, while a red LED (LED2) signifies bus errors, communication timeouts, or a CAN bus-off state. Deeper drive-level diagnostics, including monitor parameters C0159 and C0121, can be accessed using an attached Lenze E82ZBC Keypad XT or via Global Drive Control (GDC) software. Common initial checks involve verifying physical cabling, terminal shielding, correct node addresses, and line impedance with 120 Ohm terminating resistors at network endpoints. Persistent red LED indications or hardware failures cannot be serviced in the field, making replacement with a tested module through ABC Industrial Parts the most effective path to restoring production.

Programming and Configuration
The Lenze E82ZAFSC010 system bus module utilizes hardware-based parameter settings for network identification and speed settings, relying on an 8-position DIP switch block labeled S1 through S8. This onboard switch array allows technicians to directly set the node address within a range of 1 to 63 and select the corresponding transmission baud rate between 10 kbit/s and 500 kbit/s without attaching a laptop or engineering console.
For advanced system monitoring and parameter adjustment, the module interacts directly with the host 8200 Vector frequency inverter. Operators can access functional communication metrics and status codes through Lenze Global Drive Control (GDC) software or via an externally connected E82ZBC Keypad XT module. Engineering software connects through the drive to monitor diagnostic codes such as C0159 and C0121, facilitating real-time analysis of bus transmission rates and operational health.
Communication and System Integration
Designed for multi-axis coordination and distributed drive architectures, the E82ZAFSC010 provides seamless connectivity across CAN layer 2 and CANopen networking profiles. The physical interface consists of a 4-pin pluggable spring-clamp terminal block designed for reliable wiring connections. The terminal points provide dedicated contacts for CAN-High (CANH), CAN-Low (CANL), CAN Ground (GND), and cable shielding to protect high-speed process data transfer against electromagnetic interference in heavy industrial environments.
The module supports up to 63 interconnected nodes on a single System Bus topology, enabling synchronized speed and position control in applications such as automated conveyor lines, packaging machinery, material handling, and textile processing. To ensure signal integrity across the network, bus termination must be applied by placing 120 Ohm resistors at both physical ends of the CAN bus line.
Diagnostics and Status Indication
The front panel of the E82ZAFSC010 features two diagnostic LEDs that provide immediate visual feedback regarding network status and module operation. LED1 (Green) glows solid or flashes to confirm active communication and normal System Bus functionality. LED2 (Red) indicates fault conditions, flashing or illuminating continuously when communication errors, watchdog timeouts, or CAN bus-off states occur. A continuously lit red LED signifies an internal hardware error or complete bus breakdown.
Beyond visual LED signals, internal drive parameter codes C0159 and C0121 reflect real-time error states, which can be monitored via the E82ZBC Keypad XT or Global Drive Control software. These diagnostic tools allow technicians to identify communication timeouts on process data objects CANin1 through CANin3 and determine whether network issues stem from wiring faults, improper baud rates, or master controller transmission delays.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| LED1 | Green - Solid / Flashing | System Bus operational / CAN bus communication active |
| LED2 | Red - Solid / Flashing | System Bus error / Bus Off state or communication failure. Continuous illuminate indicates internal hardware or bus failure. |
Replacement and Spare Part Considerations
Replacing a Lenze 00472935 E82ZAFSC010 communication module is a straightforward procedure due to its hardware-based configuration layout. Because node addresses and communication speeds are set via onboard DIP switches S1 through S8, zero software downloads or firmware transfers are required directly on the module itself.
When preparing a spare module for service, ensure the power to the host 8200 Vector inverter is completely isolated. Carefully read the positions of the 8 DIP switches on the existing unit and set the switches on the replacement module to match exactly. Insert the new module into the drive's FIF slot, reconnect the 4-pin spring-clamp terminal block, and reapply power. Verify that LED1 illuminates green and check drive parameters C0159 or C0121 to confirm successful network integration.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |

Time lapse between process data objects exceeded defined watchdog time. | Bus cable broken, connector unplugged, bus termination missing, interference on bus line, node address incorrect. | Check wiring and shield connection, verify 120 Ohm terminating resistors, check DIP switch baud rate and node address setting, verify host controller cyclic send time. |
| CE1 | Communication Error 1 (CANin1 Object Timeout) | Process data object CANin1 was not received within the configured monitoring time. | Transmitting master stopped sending, bus interruption, incorrect transmit timing configuration. | Check master controller station status, verify CANin1 frame configuration, inspect cabling. |
