🧠 CPU & Drive-Control Function
The 9324MP.1B.62 is more than a conventional interface PCB. It is the control-processing section of the inverter, responsible for coordinating drive operation with the associated power electronics.
In a complete PICO 300 drive, the CPU/control board works together with the power section, feedback circuitry, user-control interfaces, and other drive electronics. A correctly functioning control board is therefore essential for the drive to interpret commands and execute its programmed motor-control functions.
Typical control responsibilities can include:
- Drive command processing
- Inverter operating-state management
- Motor-control calculations
- Fault and status processing
- Coordination with the drive power section
- Monitoring of connected drive circuitry
- Communication with associated control/interface hardware
Exact I/O, feedback, parameter memory, and communication functions depend on the complete PICO 300 configuration and should not be assumed from the PCB part number alone.
🔌 PICO 300 System Integration
The 9324MP.1B.62 should be considered an internal control component of the PICO 300 inverter rather than a standalone PLC or general-purpose CPU.
When replacing the board, compatibility depends on the relationship between:
- Drive model
- Power-stage configuration
- Control-board revision
- Firmware/software version
- Parameter storage
- Feedback configuration
- Connector arrangement
- External control wiring
A board with a similar 9324MP designation should not automatically be considered interchangeable with 9324MP.1B.62.
⚡ Electrical & Interface Considerations
Because this is an internal inverter CPU/control board, its electrical connections are determined by the host drive.
Before installation, verify:
- Complete 9324MP part number.
- Revision and board markings.
- Connector locations.
- Cable and harness orientation.
- Host drive model.
- Existing firmware or parameter configuration.
- Motor feedback arrangement.
- Power-board compatibility.
- Any configuration jumpers or switches.
- Stored drive parameters that may need to be restored.
⚠️ Do not connect or test the PCB outside its intended drive chassis unless the appropriate Lenze service procedure specifically permits it.
🏭 Typical Applications
The 9324MP.1B.62 can be encountered in legacy industrial motor-control equipment such as:
- 🏭 Production machinery
- ⚙️ Variable-speed motor drives
- 🔄 Conveyor systems
- 🏗️ Material-handling equipment
- 🧵 Textile and converting machinery
- 📦 Packaging machinery
- 🛠️ OEM machine tools
- 🔧 Legacy PICO 300 drive installations
Its primary value today is often as a replacement control board for existing equipment, where replacing the entire drive would require significant rewiring or mechanical modification.
🛠️ Installation & Maintenance
Before replacing the 9324MP.1B.62:
- Disconnect all incoming drive power.
- Follow the facility’s lockout/tagout procedure.
- Allow the drive’s DC bus capacitors to discharge.
- Verify the absence of hazardous voltage.
- Record connector positions and cable routing.
- Photograph the original board and its identification labels.
- Compare the replacement board with the original.
- Check the board revision and component condition.
- Transfer only configuration hardware that is specifically intended to be transferred.
- Reinstall all connectors securely.
- Inspect the drive cooling system and surrounding power components.
- Restore drive parameters as required.
- Perform a controlled power-up.
- Test the drive initially without production load.
For an older drive, also inspect the power section for failed components. A defective IGBT/power stage, feedback circuit, or power supply can damage a replacement CPU/control board if the underlying fault is not corrected.
🔍 Troubleshooting
Drive does not initialize after replacing the board
Verify the complete board number, connectors, power supplies, control-board revision, and compatibility with the host drive.
Drive powers up but generates a fault
Check stored parameters, feedback connections, control wiring, and communication between the CPU board and power section.
Motor does not respond to commands
Check the external enable/run signal, command source, parameter settings, feedback circuitry, and drive status.
Fault appears immediately after board replacement
Compare the original and replacement boards carefully. A revision or configuration mismatch can produce unexpected drive behavior.
Drive operates intermittently
Inspect connectors, PCB contamination, loose harnesses, aging components, and thermal conditions inside the drive.
Replacement board does not solve the original problem
The failure may originate from the power board, inverter power stage, feedback circuitry, external wiring, or motor rather than the CPU board.
🔄 Replacement Compatibility
The 9324MP.1B.62 belongs to a family of Lenze 9324MP control boards, but different suffixes should not be treated as direct substitutes without verification.
Examples of related part numbers include:
- 9324MP.1B.70
- 9324MP.1B.73
- 9324MP.1A.62
- 9324MP.2E.81
- 9324MP
The suffix is important because it can identify a different hardware or configuration version. Always match the complete ordering code before replacement.
❓ FAQ
What is LENZE 9324MP.1B.62?
It is a Lenze drive control board and inverter CPU board associated with the PICO 300 platform.
Is it a PLC CPU?
No. It is a dedicated inverter/drive control board rather than a general-purpose PLC CPU.
What drive platform is associated with this board?
References identify the board with the LENZE PICO 300 drive family.
Is the 9324MP.1B.62 still manufactured?
It is identified as discontinued by the manufacturer, so replacement and refurbished boards are important for legacy equipment maintenance.
Can 9324MP.1B.70 replace 9324MP.1B.62?
Do not assume so. The complete part number and drive configuration must be checked before substitution.
Does the board contain the drive power stage?
No. It is the control/CPU section. The inverter power electronics are separate.
What should I check before ordering?
Match the complete 9324MP.1B.62 part number, board revision, host drive model, connectors, and configuration.
Is this board suitable as a maintenance spare?
Yes. It is particularly useful for facilities maintaining legacy PICO 300 equipment.
What is the approximate board weight?
A parts reference lists approximately 0.90 lb (0.41 kg). Actual shipped weight can be higher because of packaging.
Can the board be installed without parameter backup?
Parameter retention and transfer depend on the specific drive configuration. Back up existing drive parameters whenever the system permits before removing the original controller.

📦 Spare-Part Recommendation
For legacy PICO 300 installations, the LENZE 9324MP.1B.62 should be maintained as a configuration-specific spare. Because this board functions as the inverter CPU/control section and is discontinued, keeping a correctly identified replacement can shorten recovery time when an aging drive develops a controller fault.
For inventory control, record the complete 9324MP.1B.62 part number, board revision, host drive model, firmware/parameter information, and connector configuration together. This helps prevent an otherwise similar 9324MP board from being installed incorrectly.
