Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00456966, model EMF2102IBCV002, is a fieldbus communication module in the Lenze System Bus (CAN) family designed for direct integration into frequency inverters and servo drives. Designed for use with Lenze 8200 vector frequency inverters and Lenze 9300 series servo and vector drives, this compact interface adapter installs directly into the host drive's Function Module Interface (FIF) slot. Operating on a 5 V DC supply drawn directly from the internal drive connection, the unit provides high-speed fieldbus connectivity for material handling, packaging machinery, and textile manufacturing equipment without requiring external power supplies or separate panel mounting space.
Field network integration is established via a galvanically isolated 5-pole pluggable screw terminal interface supporting connections for CAN-L, CAN-H, GND, and shield. Commissioning a replacement unit is straightforward, as onboard DIP switches allow hardware configuration of the node address from 1 to 63 and transmission baud rates from 10 kbit/s up to 1000 kbit/s. This physical switch setup enables rapid module swap-out without mandatory software configuration. The module supports standard CiA DS301 CANopen communication—handling both Process Data Objects (PDO) and Service Data Objects (SDO)—as well as the Lenze System Bus protocol for fast drive-to-drive speed and torque synchronization. Software diagnostics and monitoring can be performed using Lenze Global Drive Control (GDC) software, with ABC Industrial Parts providing support for acquiring tested replacement modules to keep production lines running.
Real-time monitoring and network troubleshooting are provided through front-panel CAN-RUN and CAN-ERR LED indicators along with host drive fault logging. The green CAN-RUN LED indicates operational states ranging from unpowered or reset (Off) to Pre-Operational (blinking at 1 Hz), Stopped (single flash), and Operational (solid On). The red CAN-ERR LED signals network anomalies, including invalid DIP switch settings (blinking at 1 Hz), Error Passive status (single flash), Node Guarding or Heartbeat timeouts (double flash), and Bus-Off conditions (solid On). Network faults appear on the host drive with codes CE0 through CE4, covering bus-off, PDO timeouts, warning limits, and buffer overflows. If error code CE4 persists after re-seating the module in the FIF slot, an internal hardware failure has occurred. Because internal board-level faults cannot be serviced in the field, sourcing a tested exchange unit from ABC Industrial Parts is the standard path to restore machine operation.

Programming and Configuration
Hardware setup on the Lenze 00456966 EMF2102IBCV002 is handled primarily through onboard DIP switches accessible on the module front panel. These physical switches allow technicians to select node addresses between 1 and 63 and select standard bus baud rates ranging from 10 kbit/s to 1000 kbit/s (1 Mbit/s). Because the operational address and network speed are set via hardware, replacement modules can be configured and deployed into host drives with zero software configuration needed.
For comprehensive system monitoring and parameter access, the module connects to Lenze Global Drive Control (GDC) software. Through GDC, engineers can inspect CANopen protocol status registers, verify cyclic data transfer settings, and review drive system parameter monitoring over the network.
When replacing a module, matching the DIP switch positions on the donor or replacement unit to match the original settings ensures immediate network compatibility upon host drive power-up.
Communication and System Integration
The EMF2102IBCV002 communication module provides multi-protocol fieldbus integration for automated production lines, packaging machines, and conveyor systems. It supports the CiA DS301 CANopen profile for real-time motion control and parameter supervision using Process Data Objects (PDO) and Service Data Objects (SDO), as well as the proprietary Lenze System Bus protocol optimized for high-speed drive-to-drive speed and torque synchronization.
Physical connection to the CAN network is made through a 5-pole pluggable screw terminal block accommodating CAN-L, CAN-H, GND, and shield wiring. The interface is galvanically isolated, protecting host drive electronics against electrical noise, differential ground potentials, and ground loops common in complex industrial control panels.
The module operates across a selectable communication range from 10 kbit/s to 1000 kbit/s. Operating within the internal FIF slot of Lenze 8200 vector and 9300 series drives, it enables centralized PLC control and parameter monitoring across multi-axis system architectures.
Diagnostics and Status Indication
Visual diagnostic feedback is provided on the module front panel by two status LEDs: green CAN-RUN and red CAN-ERR. These indicators offer immediate feedback regarding network initialization, node operational modes, DIP switch configuration status, and communication state errors.
In addition to LED indications, host drive systems incorporate internal fault logging for the communication interface, recording specific error codes from CE0 through CE4. Further detailed diagnostics and CANopen protocol register status can be monitored using Global Drive Control (GDC) software or standard fieldbus supervision tools.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Off / Blinking (1 Hz) / Single Flash / Solid On | Off: Reset, no supply voltage, or drive unpowered. Blinking (1 Hz): Pre-Operational state. Single flash: Stopped state. Solid On: Operational state. |
| CAN-ERR | Red - Off / Blinking (1 Hz) / Single Flash / Double Flash / Solid On | Off: Normal operation without errors. Blinking (1 Hz): Invalid DIP switch setting. Single flash: Error Passive state. Double flash: Heartbeat or Node Guarding error. Solid On: Bus Off state (Permanent ON with RUN OFF indicates hardware fault). |
Replacement and Spare Part Considerations
Installing or replacing a Lenze 00456966 module requires opening the host inverter panel and inserting the card directly into the host drive's Function Module Interface (FIF) slot. Before seating or removing the card, always power down the main AC supply to the host inverter or servo drive to prevent damage to internal card slot connectors.
When replacing a unit, verify that the replacement card's DIP switch banks match the node address (1–63) and baud rate (10–1000 kbit/s) of the failed module. Because hardware switch settings dictate network node settings, matching these positions allows plug-and-play installation without reloading project software. Ensure that the 5-pole pluggable terminal connector is wired with correct signal polarity (CAN-L, CAN-H, GND) and that cable shielding is properly grounded.
The EMF2102IBCV002 module is compatible across Lenze 8200 vector frequency inverters and Lenze 9300 series servo and vector drives. If a replacement module experiences persistent initialization errors such as code CE4 upon power-up, verify that the board is firmly seated in the FIF slot before determining whether hardware repair or module replacement is required.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | CAN Communication Error / Bus-Off | CAN controller has entered Bus-Off state due to excessive transmission or reception errors. | Broken or shorted CAN bus line, incorrect baud rate, missing 120 Ohm terminating resistor, severe electromagnetic interference. | Inspect CAN cabling and grounding. Verify terminating resistors at both ends of the bus. Confirm DIP switch baud rate matches network master. |
| CE1 | CAN Monitoring Time Out / PDO Timeout | Process data object or cyclic message timeout was exceeded. | Master controller stopped sending data, watchdog time set too short, cable disconnected. | Check PLC / CAN master controller operational status. Verify CAN watchdog timing and network traffic load. |
| CE2 | CAN Bus Warning Limit Reached | CAN controller error counter reached warning limit (Error Passive condition). | Loose cable shield, interference on communication lines, marginal baud rate synchronization. | Check cable shielding and grounding. Verify physical bus wiring quality and cable routing away from high-voltage cables. |
| CE3 | CAN Receive Queue Overflow | Internal receive buffer memory overflow due to excessive traffic. | Too many CAN messages sent to node in short time frame, bus overload. | Reduce network message transmission frequency or increase bus baud rate. |
| CE4 | CAN Module Initialization / Hardware Error | Function module failed to initialize or experienced internal hardware failure. | Poor contact in FIF interface slot, defective communication board. | Power down drive, re-seat module firmly in slot, power up drive. Internal hardware fault — return unit for repair or replace module if error persists. |
Frequently Asked Questions
How do I configure the node address and baud rate on the Lenze 00456966?
Node addressing (1 to 63) and baud rates (10 kbit/s to 1000 kbit/s) are set directly on the module using onboard hardware DIP switches. No software setup is required to configure these network parameters during installation.
Which drives are compatible with the EMF2102IBCV002 communication card?
The module is designed to plug directly into the Function Module Interface (FIF) slot of Lenze 8200 vector frequency inverters and Lenze 9300 series servo and vector drives.
What does error code CE0 indicate on a host Lenze drive?
Code CE0 indicates a CAN Communication Error or Bus-Off state, caused by broken or shorted bus lines, mismatched baud rates, missing 120 Ohm termination resistors, or severe electromagnetic interference.
Is external power required for the Lenze EMF2102IBCV002 module?
No external power supply is needed. The card draws its required 5 V DC supply (100 mA current consumption) directly from the host drive through the internal FIF interface slot.
What action should be taken if the red CAN-ERR LED is solid On and CAN-RUN is Off?
A solid red CAN-ERR LED combined with an unlit CAN-RUN LED indicates a Bus Off condition or module hardware fault. Power down the drive and re-seat the card in the FIF slot. If the error persists or fault code CE4 appears, the module has suffered an internal hardware fault and requires repair or replacement.
