Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZAFIC010 Interbus PT is a fieldbus communication card designed for Lenze 8200 vector frequency inverters, 8200 motec inverters, and Drive PLC controllers. Operating as a plug-in function module (FIF), the unit mounts directly into the front interface slot of the host drive without requiring external control power wiring, receiving its required 5 V DC operating supply directly from the internal bus of the drive. This module integrates host inverters into established INTERBUS industrial fieldbus networks across automotive assembly lines, packaging machinery, and material handling systems.
Physical connection to the fieldbus network is established through a standard 9-pin D-Sub connector, supporting standard INTERBUS RS422 communication at a fixed transmission rate of 500 kbit/s. Commissioning a replacement E82ZAFIC010 requires matching the configured cyclic process data length, which supports between 1 and 4 process data (PCD) words for transferring speed setpoints, actual values, and drive control commands. Parameter access and network setup are managed via Lenze Global Drive Control (GDC) software or an optional E82ZBC pluggable keypad, with drive parameters C0091, C0150, and C0151 storing function module status and process data mappings in the non-volatile memory of the host drive. ABC Industrial Parts provides technical support and tested replacement units to streamline spare module integration.
Onboard diagnostic LEDs situated on the front panel provide real-time status monitoring for network activity, remote bus disconnect, and internal module state. Green CC / BA indicators display active cable control and cyclic data transfer, yellow RD indicates remote bus suppression, and red FAIL / ERR highlights initialization or internal hardware faults. If persistent communication errors such as fault CE0 or hardware faults such as CE2 occur that cannot be resolved through re-seating or cabling checks, internal circuit failures are not field-serviceable, making a tested replacement unit from ABC Industrial Parts the most efficient path back to production.

Programming and Configuration
Parameter setting and network integration for the E82ZAFIC010 are conducted through drive-based parameters using Lenze Global Drive Control (GDC) software or the pluggable E82ZBC keypad. Parameter C0091 indicates the current status of the function module in the FIF slot, while parameters C0150 and C0151 handle process data input and output word mapping.
The module supports configurable cyclic process data lengths ranging from 1 to 4 PCD words, permitting precise mapping of control words, setpoint values, status words, and actual drive values to match the INTERBUS master configuration. All parameter settings and mapping structures are stored within the non-volatile memory of the host drive controller, simplifying module replacement when maintaining installed equipment.
Communication and System Integration
The E82ZAFIC010 connects Lenze 8200 vector inverters, 8200 motec drives, and Drive PLC systems into INTERBUS control architectures using standard RS422 differential signaling. The physical link is established using an industry-standard 9-pin D-Sub fieldbus connector, operating at a fixed network transmission rate of 500 kbit/s.
Designed to slide into the front FIF function module slot of the host drive, the module draws operating power directly from the 5 V DC internal rail of the drive controller. This slot-based interface eliminates external 24 V DC power wiring and reduces overall control cabinet complexity while establishing real-time communication between central controllers and distributed variable frequency drives.
Diagnostics and Status Indication
Real-time visual monitoring is provided via three status LEDs on the front panel of the E82ZAFIC010. The green CC / BA LED indicates cable control and active bus communication when lit solid, with dark or flashing states signaling cable disconnects or communication errors. The yellow RD LED illuminates when the outgoing remote bus is disabled or suppressed, and the red FAIL / ERR LED lights up in response to module initialization errors or internal hardware faults.
Detailed parameter diagnostics can be monitored through drive parameter C0091 using the GDC diagnostic window or an attached keypad. Process data monitoring registers C0150 and C0151 allow technicians to verify word assignments and inspect real-time cyclic data exchange between the INTERBUS master controller and the inverter.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CC / BA | Green - Solid / Flashing / Off | Cable Control / Bus Active state. Green indicates active INTERBUS connection and data transfer. Off or flashing indicates cable/bus connection error. |
| RD | Yellow - Solid / Off | Remote Bus Disable. Yellow indicates that the outgoing remote bus interface is disconnected or suppressed. |
| FAIL / ERR | Red - Solid / Off | Red LED indicates internal hardware fault or INTERBUS module initialization failure. Red persistent light indicates non-field-serviceable board failure requiring module replacement. |
Replacement and Spare Part Considerations
Before replacing an E82ZAFIC010 communication module, ensure the host frequency inverter is fully powered down. Slide the module firmly into the front FIF slot to guarantee complete contact with the internal backplane connector, which supplies 5 V DC operating power and internal communication lines.
Because module configuration and parameter mapping are retained in the non-volatile memory of the host drive, replacing a faulty module with an identical E82ZAFIC010 card typically does not require re-downloading parameter sets. However, technicians must verify that the process data word count configured in drive parameters C0150 and C0151 corresponds to the active INTERBUS master hardware configuration to avoid CE3 process data configuration errors.
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 to Function Module (FIF) | Communication interruption between the 8200 vector basic inverter and the E82ZAFIC010 function module. | Module not correctly seated in FIF slot; severe EMC interference; internal hardware failure of E82ZAFIC010 function module. | Check mechanical fitting of module; check grounding and shield connections; if error persists after power cycle, replace function module. |
| CE1 | Process Data Input Error / Bus Time-out | INTERBUS cyclic process data transfer timeout or interruption. | INTERBUS master stopped; damaged fieldbus cable; incorrect baud rate or master configuration. | Check INTERBUS line connections, master PLC status, and bus termination; verify cable integrity. |
| CE2 | Function Module Hardware Error | Internal self-test or watchdog fault on the E82ZAFIC010 communication module. | Defective internal components or EEPROM error on the communication module. | Internal hardware fault — return unit for repair or replace with a new E82ZAFIC010 module. |
| CE3 | Process Data Output Configuration Error | Mismatched process data length or unassigned parameter mapping in the drive. | Configured PCD word count in drive parameters does not match master station hardware configuration. | Reconfigure drive parameter C0150/C0151 or INTERBUS master process data mapping. |
Frequently Asked Questions
Which Lenze drive series support the E82ZAFIC010 Interbus module?
The E82ZAFIC010 module is compatible with Lenze 8200 vector frequency inverters (0.25 kW to 90 kW), Lenze 8200 motec inverters, and Lenze Drive PLC units equipped with a front FIF function module slot.
Does the E82ZAFIC010 require an external power supply?
No, the module receives its 5 V DC power supply directly from the internal bus of the host drive when plugged into the FIF slot.
Which software is used to configure parameters on the E82ZAFIC010?
Parameters and diagnostic monitoring are accessed using Lenze Global Drive Control (GDC) software or an E82ZBC pluggable keypad connected to the host drive.
What does drive error code CE0 signify?
Fault CE0 indicates a communication breakdown between the host inverter and the E82ZAFIC010 module, typically caused by loose seating in the FIF slot, EMC interference, or an internal hardware failure on the module.
What should be done if the red FAIL / ERR LED remains continuously lit?
A persistent solid red FAIL / ERR LED indicates an internal hardware or EEPROM initialization failure. Power cycle the drive; if the light remains red, the module cannot be serviced in the field and must be repaired or replaced.
