Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 9324MP.1B.62.V01 is a servo controller control board designed for the Lenze 9300 Servo family, specifically for 9300 Master Position servo inverters. Operating on a nominal 24 V DC control supply drawing 1 A, this plug-in control module attaches directly to Lenze 9300 power section units to deliver high-precision motion control, electronic gearing, registration mark positioning, and synchronized master-slave multi-axis positioning. It serves as the primary processing unit for motor feedback evaluation, terminal I/O processing, and system communication across packaging, textile, printing, converting, and machine tool automation systems.
For physical interface integration, the board features 8 digital inputs, 4 digital outputs, 2 bipolar analog inputs (-10 V to +10 V with 12-bit resolution), and 2 bipolar analog outputs. Motor feedback is routed through a 15-pin Sub-D connector supporting resolvers with a 10 kHz evaluation frequency, as well as SinCos absolute encoders and incremental encoders. Networking across drive axes is provided via an onboard CAN system bus operating up to 500 kbps on terminals X4 and X5. A dedicated Automation Interface slot on the front accepts optional communication modules like PROFIBUS-DP (EMF2131IB or EMF2133IB), INTERBUS, LECOM, or an EMF2102IB keypad module. Putting a spare unit into service requires parameter transfer, as the board stores up to four non-volatile parameter sets (PAR0 through PAR3) in internal EEPROM memory using Lenze Global Drive Control (GDC V4.x+) or EASY Starter software. ABC Industrial Parts can assist in sourcing fully tested replacement units and managing parameter extraction to restore motion sequences smoothly.
Diagnostic conditions are visually indicated by two front panel LEDs. A green READY LED illuminates solid when the drive is enabled and operational, flashes when in the controller-inhibited IMP state, and turns off if the control supply fails or an internal board fault occurs. A red TRIP LED stays solid during active fault conditions that inhibit drive output, flashes for warnings, and remains off during normal operation. Detailed fault tracking is accessible via keypad display, GDC or EASY Starter diagnostic views, or the fault history buffer stored in codes C0161 through C0168. When experiencing critical system failures such as an internal micro-controller system error (code H05) or persistent EEPROM corruption (code EEr), internal hardware components are not field-serviceable, making drive board replacement or professional repair through ABC Industrial Parts the most efficient path back to production.

Programming and Configuration
Configuration of the Lenze 9324MP.1B.62.V01 control board relies on Lenze Global Drive Control (GDC version 4.x or higher) or EASY Starter engineering software tools. The control board contains non-volatile EEPROM memory capable of holding up to four distinct parameter sets, designated PAR0 through PAR3. This multi-parameter architecture allows users to store backup configurations directly on the board or switch operational profiles for flexible machinery setups.
When commissioning or replacing a module, parameters can be transferred electronically via PC connected over fieldbus/communication interfaces, or copied directly using an EMF2102IB plug-in keypad module. Reading parameter sets from a donor or existing control board and transferring them to a replacement unit ensures that motor control loops, I/O mapping, and motion profiles are mirrored without manual re-entry.
Communication and System Integration
System communication on the 9324MP.1B.62.V01 control board is anchored by an integrated Lenze CAN system bus interface, routed through terminals X4 and X5. Operating at transmission speeds up to 500 kbps, this interface enables synchronized master-slave axis coupling and high-speed multi-axis motion networks across Lenze 9300 servo drives. Proper line termination using 120 Ohm resistors at both physical ends of the bus is required to maintain reliable signal integrity.
Higher-level fieldbus integration is achieved through the front Automation Interface (AIF) expansion slot. This slot accommodates modular fieldbus adapters including PROFIBUS-DP interfaces (EMF2131IB and EMF2133IB), INTERBUS, and LECOM RS-232 or RS-485 communication cards. Interfacing options allow seamless connection to central PLCs, master controllers, and human-machine interfaces without modifying the core control hardware.
Diagnostics and Status Indication
The board provides immediate visual feedback via two dedicated LED indicators on the front panel. System status and operational states can also be monitored digitally using the EMF2102IB keypad module, the GDC diagnostic monitor, or EASY Starter software. Internal diagnostic logs are continuously updated in a non-volatile fault history memory buffer spanning codes C0161 to C0168, allowing maintenance staff to trace past operational faults and warning events chronologically.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (READY / Operation) | Green - Solid / Flashing | ON: Drive enabled and running. Flashing: Controller inhibited (IMP state), ready for operation. OFF: Control supply missing or internal board fault. |
| Red LED (TRIP / Fault) | Red - Solid / Flashing | ON: Fault condition active (TRIP), drive output inhibited. Flashing: Warning or message condition active. OFF: No active trip/warning. |
Replacement and Spare Part Considerations
Replacing a Lenze 9324MP.1B.62.V01 control board requires matching the exact part number to ensure hardware and firmware compatibility with the underlying 9300 servo power section. Because the board handles motor feedback routing, terminal assignments, and fieldbus communication, swapped units must be configured with the specific parameter file (PAR0 to PAR3) corresponding to the machine application before operating connected motors.
Prior to mounting a replacement board, technical staff should verify that all optional fieldbus modules (such as PROFIBUS EMF2131IB/EMF2133IB) or keypads are securely seated in the front AIF slot. Wiring connections across control terminals, resolver/encoder ports (terminal X6, X8/X9), and the CAN system bus (terminals X4/X5) must be verified, ensuring correct 120 Ohm termination resistors are present on the CAN bus to prevent communication timeouts.
