Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 9324MP.2D.80 is a microprocessor control board serving as the central processing and command unit for Lenze 9300 Series Servo and Servo PLC drives. Operating on an external 24 V DC control supply, the card maintains continuous processing logic and parameter retention even during main AC power supply interruptions. Hardware revision 2D and variant 80 designate this control module, which manages precise multi-axis positioning and synchronized motion control across automated industrial machinery, including packaging lines, material handling systems, textile manufacturing, and printing equipment.
Connecting the 9324MP.2D.80 into an existing installation requires matching its physical feedback and network interfaces to the host drive power chassis. The board incorporates a Sub-D resolver input (connector X7), an incremental encoder RS422 input (connector X8), and a frequency output repeater interface (connector X9) for downstream axis synchronization, alongside 8 digital inputs, 4 digital outputs, 2 bipolar analog inputs, and 2 bipolar analog outputs. An integrated modular Automation Interface (AIF) slot accommodates plug-in fieldbus adapters, including PROFIBUS-DP (EMF2133IB), CANopen (EMF2172IB), and INTERBUS (EMF2111IB) modules. Commissioning a spare unit is rarely plug-and-run; parameter settings and control programs stored across up to four memory sets in the non-volatile EEPROM must be transferred using a Keypad XT operator module (EMF2102IB or EMF2101IB) or Lenze Global Drive Control (GDC) software. ABC Industrial Parts can support maintenance teams with parameter extraction and data recovery when transferring operating profiles from an unreadable board.
Diagnostic monitoring on the front faceplate is provided by two status LEDs: a green DRIVE READY indicator and a red DRIVE ERROR indicator. Additional status interrogation can be performed by reading error codes on the Keypad XT, analyzing the C0168 parameter history buffer, checking CAN system bus status words, or using the GDC diagnostic monitor. First-line field checks for trip conditions like OC1 overcurrent, OU overvoltage, or LU undervoltage involve inspecting line fuses, motor insulation, braking resistors, and control supply voltages. Internal board faults such as EEPROM corruption (EER) or central processing self-test failure (H05) indicate hardware failure on the board itself that cannot be serviced in the field. Installing a fully tested exchange board from ABC Industrial Parts offers a fast route to restoring machine operation.

Programming and Configuration
Configuring the Lenze 9324MP.2D.80 control board requires dedicated engineering software tools or operator hardware. Primary parameter management is conducted using Lenze Global Drive Control (GDC) software connected through a serial interface or via direct input on a Keypad XT operator module (EMF2102IB / EMF2101IB). The card incorporates non-volatile EEPROM memory configured to store up to four complete, independent parameter sets directly on the board.
In 9300 Servo PLC applications, custom motion sequences and PLC programs are written and compiled using Drive PLC Developer Studio (DDS). When replacing a controller board, extracting parameter files from the original board via GDC software and restoring them to the replacement unit ensures accurate motor tuning gains, digital I/O function assignments, and fieldbus addresses. If a memory fault recovery procedure is required, a factory parameter reset can be initiated via parameter C0002=1 prior to reloading valid application projects.
Communication and System Integration
The 9324MP.2D.80 features an onboard CAN system bus capable of transmission speeds up to 500 kbps. This integrated bus allows high-speed multi-axis drive-to-drive communication, synchronization, and master-slave control without requiring external motion controller hardware. Network stability across the system bus relies on correct 120-ohm bus termination resistors at line ends and matched baud rates across all connected nodes.
Broader integration into industrial fieldbus networks is achieved through the integrated Automation Interface (AIF) expansion slot. This multi-pin slot accepts option modules including PROFIBUS-DP (EMF2133IB), CANopen (EMF2172IB), INTERBUS (EMF2111IB), or LECOM serial communication cards. Physical feedback connections are made directly on the board faceplate via connector X7 for Sub-D resolver feedback, connector X8 for RS422 incremental encoder signals, and connector X9 for frequency signal repeating to downstream slave drives.
Diagnostics and Status Indication
Operating status and primary fault conditions on the 9324MP.2D.80 are indicated by two status LEDs located on the faceplate. The green DRIVE READY LED lights solid during normal operation, flashes when a controller inhibit or warning condition exists, and turns off if control power is lost or a hardware failure occurs. The red DRIVE ERROR LED lights solid during active TRIP conditions, flashes when a warning threshold is reached, and remains off during normal fault-free operation.
Detailed diagnostics are accessible by interrogating the C0168 parameter history buffer, which records recent error codes and sub-codes. Maintenance engineers can read fault records directly through the Keypad XT module display or via the online diagnostic monitor in Global Drive Control (GDC) software. Fault states and system status words are also transmitted across the CAN system bus or installed fieldbus network to upper-level controllers.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid / Flashing / Off | ON = Drive is ready / operating normally; BLINKING = Controller inhibit or warning active; OFF = Drive not powered or internal failure |
| DRIVE ERROR | Red - Solid / Flashing / Off | ON = Active TRIP fault condition; BLINKING = Warning condition present; OFF = Normal operation without fault |
Replacement and Spare Part Considerations
When replacing a Lenze 9324MP.2D.80 control board, verify that the complete part number, hardware revision (2D), and variant code (80) match the original unit. Deviations in revision level or variant codes can lead to parameter mismatch, I/O pin allocation differences, or incompatibility with the installed drive power unit.
A replacement board must be configured with the parameter values from the original machine. EEPROM parameter sets should be restored using Global Drive Control (GDC) software or transferred via a Keypad XT operator module to maintain correct motor feedback settings, current limits, and communication node addresses. Any option card mounted in the Automation Interface (AIF) slot, such as a PROFIBUS EMF2133IB module, must be transferred to the replacement board and verified for firm seating and correct hardware switch settings.

Frequently Asked Questions
What software is used to program and parameterize the Lenze 9324MP.2D.80 control board?
Drive parameters are configured using Lenze Global Drive Control (GDC) software or directly via a Keypad XT operator module (EMF2102IB or EMF2101IB). For 9300 Servo PLC models, custom PLC user programs are developed using Drive PLC Developer Studio (DDS).
Can I install a replacement 9324MP.2D.80 board without configuring software parameters?
No. Replacement boards contain factory default parameters. You must load your machinery's specific parameter backup into the board's EEPROM via Keypad XT or GDC software to restore motor settings, I/O mapping, and fieldbus communication.
Which fieldbus modules fit into the AIF slot on the 9324MP.2D.80 board?
The Automation Interface (AIF) slot supports optional communication modules including PROFIBUS-DP (EMF2133IB), CANopen (EMF2172IB), INTERBUS (EMF2111IB), and LECOM serial interface modules.
What does fault code EER indicate on the 9324MP.2D.80 control board?
Fault code EER indicates an internal EEPROM checksum error. You can attempt a factory reset by setting parameter C0002=1; if the fault condition persists after clearing, the control board hardware is defective and must be replaced.
How do the front status LEDs indicate normal operation on the 9324MP.2D.80?
Under normal operating conditions, the green DRIVE READY LED is illuminated solid and the red DRIVE ERROR LED is off. A flashing green LED indicates a warning or controller inhibit, while a solid red LED signals an active TRIP fault.
