Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00375353, model designation 33.2111IB.1A.11, is an industrial fieldbus communication card from the 2100 Series Fieldbus Modules engineered to integrate VFDs and servo drives into INTERBUS networks. Operating as a direct plug-in function module into the internal function module (FIF) slot, this board provides fieldbus connectivity for Lenze 8200 vector, 8200 motec, and 9300 series drive controllers. The module receives its required 5 V DC supply voltage internally from the host drive, eliminating the need for external power supply wiring and simplifying mounting inside control cabinets.
Fieldbus connections are established via dual 9-pin Sub-D connectors using RS-422 differential signaling, featuring a female port for the incoming remote bus and a male port for outgoing bus extension. Operating at a transmission speed of 500 kbit/s and utilizing DriveCom Profile 21, the card supports both cyclic process data exchange and parameter channel (PCP) access. Operational parameters are stored in the non-volatile memory of the host drive controller, allowing quick module replacement without re-parameterization. System configuration and monitoring can be performed using Global Drive Control (GDC) software, an Operating Keypad 8201 or Keypad XT, or INTERBUS master engineering tools like PC Worx. ABC Industrial Parts can assist maintenance teams needing replacement modules or tested spares to keep production lines running smoothly.
For immediate visual verification and diagnostic checks, five status LEDs are located on the module front panel: PWR / READY, CC (Cable Control), BA (Bus Active), RD (Remote Bus Disabled), and ERR / FAIL. In addition to physical indicators, internal diagnostic registers C0150 and C0151 can be queried via drive software or INTERBUS master tools such as CMD and PC Worx. First-line troubleshooting for errors like communication loss (CE0) or process data timeouts (CE1) includes verifying module seating in the FIF slot and checking cable shielding and master status. If an internal board fault or communication failure persists, replacing the card with a tested unit from ABC Industrial Parts offers a fast solution to restore system communication.

Programming and Configuration
The Lenze 00375353 module supports drive communication and parameterization over INTERBUS in compliance with DriveCom Profile 21. Utilizing the Periphery Communication Protocol (PCP) channel alongside cyclic process data, PLC software environments such as PC Worx or Lenze Global Drive Control (GDC) software can access drive registers remotely to perform process control, adjust parameters, and read status values.
Because operating configuration and motor parameters reside within the host drive controller's non-volatile memory rather than on the communication card itself, commissioning a replacement card is straightforward. Field parameters and diagnostic parameters can also be accessed locally using a Keypad XT or Operating Keypad 8201 plugged directly into the host drive.
Communication and System Integration
Designed for seamless integration into industrial automation networks, the 33.2111IB.1A.11 module links Lenze drive controllers to an INTERBUS master network operating at 500 kbit/s. Physical connection is established using RS-422 differential signals via two standard 9-pin Sub-D connectors: a female socket for incoming remote bus signals and a male plug for extending the bus segment to downstream nodes.
The module adheres to DriveCom Profile 21, ensuring structured parameter access and process data handling when connecting Lenze 8200 vector, 8200 motec, or 9300 drives to INTERBUS master controllers, such as Phoenix Contact PLCs. This structure enables application across packaging machinery, material handling conveyors, automotive lines, and textile processing systems.
Diagnostics and Status Indication
Real-time diagnostic capabilities are built directly into the front panel of the Lenze 00375353 communication module. Five dedicated LEDs display immediate visual feedback on internal operating voltage, fieldbus cable health, cyclic data transmission, outgoing segment status, and hardware fault conditions.
For detailed network troubleshooting, fieldbus status registers C0150 and C0151 in the host drive can be examined using Global Drive Control (GDC) software, drive keypads, or INTERBUS master diagnostic applications such as CMD and PC Worx.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| PWR / READY | Green - Solid | Operating voltage supplied internally by host drive controller; module initialization complete. |
| CC (Cable Control) | Green - Solid | Incoming INTERBUS remote bus connection established and physically healthy. |
| BA (Bus Active) | Green - Solid | INTERBUS data transmission active and master is polling the module. |
| RD (Remote Bus Disabled) | Yellow/Red - Solid | Outgoing remote bus interface is switched off or disconnected. |
| ERR / FAIL | Red - Solid | Module hardware fault or internal communication loss with host drive controller. |
Replacement and Spare Part Considerations
When swapping a damaged communication card, ensure the host drive is fully isolated from power before inserting the replacement 00375353 module into the internal Function Module (FIF) slot. Direct power delivery from the drive's internal 5 V DC rail means no separate auxiliary power wiring is needed.
Since drive parameters are stored in the memory of the host drive controller, replacing the card generally does not require restoring a parameter backup file. After seating the replacement module securely, verify that the 9-pin Sub-D connectors are fastened tightly and inspect shielding connections to prevent EMC interference.
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 | Communication failure between host drive controller and fieldbus module 2111IB. | Module not firmly seated in slot; internal connector damaged; hardware fault in 2111IB module. | Power down drive, re-seat module securely in slot. If persistent, replace module or drive controller. |
| CE1 | Process Data Monitoring Timeout | Watchdog timeout for process data transmission on INTERBUS network. | INTERBUS master stopped cyclic communication; cable broken or unplugged; task overload on master. | Check INTERBUS cables and connectors. Verify INTERBUS master PLC status and communication cycle. |
| CE2 | INTERBUS Bus Error | Physical bus fault detected on remote bus segment. | Loose cable, broken shield/grounding connection, high EMC noise interference, segment length exceeded. | Inspect Sub-D connections and shielding. Verify bus topology and total cable length. |
| CE3 | Parameter Channel Fault | Error during PCP parameter access or invalid parameter structure requested by master. | PCP telegram error; index/subindex out of range; parameter write lock active on drive. | Check parameter index in INTERBUS master PLC configuration and release write access on host drive. |
Frequently Asked Questions

Does the Lenze 33.2111IB.1A.11 card require external power wiring?
No, the card receives its 5 V DC operating voltage directly from the host drive through its internal slot connector.
What do the diagnostic LEDs on the front of the module show?
The five LEDs display internal power status (PWR / READY), incoming cable connection (CC), cyclic bus activity (BA), disabled remote bus state (RD), and internal module or communication errors (ERR / FAIL).
Do I need to re-parameterize the drive after replacing the fieldbus card?
No, operating parameters are stored in the non-volatile memory of the host Lenze drive controller, allowing replacement cards to be installed without re-entering parameters.
What should I check if the drive displays fault code CE0?
Fault CE0 indicates a communication failure between the host drive and the 2111IB module. Power down the system, ensure the module is fully seated in the FIF slot, and inspect internal connectors for damage.
