Lenze 9325MP.1B.73 Main Control Board – 9300 Series 5.5 kW
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 9325MP.1B.73 is the main microprocessor controller circuit board designed for Lenze 9300 Series 5.5 kW (9325 frame size) servo drives and frequency inverters. Operating as the central processing unit within the drive assembly, this control board handles closed-loop motor feedback, internal algorithm execution, and system-level control. Hardware features include an integrated 500 kbps CAN system bus interface, a dedicated Automation Interface (AIF) expansion slot, and a 15-pin Sub-D connector for motor feedback device connection.
Integrating the unit into existing equipment relies on the onboard 15-pin Sub-D connector for resolver or encoder signals, alongside the flexible AIF slot that accepts fieldbus expansion modules such as the EMF2133IB PROFIBUS-DP or EMF2102IB keypad module. Commissioning a replacement board requires transferring saved drive parameters to align the controller with the specific motor and operating environment. The onboard non-volatile EEPROM retains up to four independent parameter sets, which can be uploaded or downloaded using Lenze Global Drive Control (GDC) software or an EMF2102IB keypad. Technicians can rely on support from ABC Industrial Parts to verify parameter extraction options or source a ready-to-install replacement module.
Diagnostic assessment on the board is managed via two status LEDs—TRIP/Fault and RUN/Ready—as well as the keypad error code menu, GDC diagnostic history buffer, and system bus registers. Flashing or solid LED indications signal operating conditions such as active controller inhibit or system trip faults. While field maintenance covers parameter reloading and cabling checks, persistent internal hardware errors like memory or self-test faults cannot be repaired on-site. In these instances, obtaining a tested exchange board from ABC Industrial Parts offers a fast and reliable path to restoring machine operations.

Programming and Configuration
The Lenze 9325MP.1B.73 controller board utilizes non-volatile onboard EEPROM memory capable of holding up to four complete parameter sets. Parameter management is conducted primarily through Lenze Global Drive Control (GDC) software connected via a suitable communication interface or directly using an EMF2102IB XT keypad module attached to the Automation Interface slot.
During commissioning or replacement, parameter sets stored in the EEPROM allow quick backup and restoration of motor calibration settings, application parameters, and fieldbus node addresses. When swapping a faulty board, transferring the stored parameter file from GDC software or downloading a parameter set from the keypad module ensures the replacement board operates with identical control curves and limit settings.
Communication and System Integration
Communication across the automated control architecture is supported through an integrated 500 kbps CAN system bus and a dedicated Automation Interface (AIF) slot. The system bus provides real-time inter-drive synchronization and multi-axis coordination across Lenze 9300 series drives, communicating velocity, torque, and status data without needing external gateways.
The modular AIF slot allows seamless integration into industrial fieldbus networks using plug-in communication modules. Options include the EMF2133IB PROFIBUS module or LECOM RS232/RS485 interfaces, allowing the 9325MP.1B.73 to communicate with supervisory PLCs and higher-level automation systems. Motor feedback routing is handled through a 15-pin Sub-D interface supporting resolvers, incremental encoders, and absolute encoders.
Diagnostics and Status Indication
System diagnostics for the 9325MP.1B.73 control board are displayed directly through onboard status LEDs, an optional keypad interface, or connected software tools. The board incorporates two visual status indicators: a red TRIP / Fault LED and a green RUN / Ready LED. These indicators convey real-time operating states, controller inhibition, and active fault conditions.
Detailed troubleshooting data can be retrieved using the keypad error code menu, the Lenze Global Drive Control (GDC) diagnostic history buffer, or system bus diagnostic registers. Fault conditions such as overtemperature, overvoltage, motor feedback loss, or communication timeouts are logged with specific code identifiers to assist in rapid fault isolation.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| TRIP / Fault | Red - Solid or Flashing | Indicates a trip fault condition or active error state |
| RUN / Ready | Green - Solid or Flashing | Solid green indicates controller active and ready; flashing green indicates controller inhibit (CINH active) |
Replacement and Spare Part Considerations
When replacing a damaged control board in a 5.5 kW Lenze 9325 drive, verify that the replacement part number matches 9325MP.1B.73. Because this board houses the main microprocessor and drive configuration, direct hardware swapping must be followed by parameter restoration to match the drive to its motor and fieldbus network.
Before removing the original board, attempt to upload the active parameter sets using GDC software or copy them to an EMF2102IB keypad module. Ensure that any option modules installed in the AIF slot, such as the EMF2133IB PROFIBUS module, are seated properly on the replacement board and that feedback cables attached to the 15-pin Sub-D connector are securely fastened.
