Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF9324-EV (part number 13432058) is an 11 kW AC frequency inverter from the Lenze 9300 Vector product family, engineered to regulate three-phase motor speed and torque in demanding continuous process and motion control setups. Operating on a three-phase mains supply voltage range of 320 V AC to 528 V AC, this drive supplies a continuous output current of 23.5 A at an 8 kHz switching frequency with an adjustable output frequency spanning 0 to 480 Hz. To support a wide array of industrial machinery, the unit accommodates flexible control modes, including V/f characteristic control, sensorless vector control, and closed-loop vector control.
Interfacing the inverter into control systems is managed through an onboard CAN system bus operating up to 500 kbit/s and a dedicated Automation Interface (AIF) expansion slot. The AIF slot accepts plug-in fieldbus modules, such as the EMF2133IB or EMF2102IB PROFIBUS-DP adapters, or serial communication modules. Putting a replacement EVF9324-EV into operation requires matching parameter configurations with the original unit, as the internal non-volatile EEPROM stores up to four switchable parameter sets. Commissioning engineers can transfer parameters directly using the plug-in Keypad XT EMZ9371BC or via Global Drive Control (GDC) engineering software version 4.x+ using a PC system bus adapter, with ABC Industrial Parts providing parameter extraction support from original drives when required.
Status overview and immediate fault indication are provided on the front panel by three status LEDs: RUN (green) for normal operation, TRIP (red) for fault trips, and IMP (yellow) for pulse inhibit state. Detailed troubleshooting is supported by reading numerical error codes through the Keypad XT module or accessing diagnostic code registers C0161 through C0164, which retain the drive's historical fault log. First-line field checks should verify three-phase mains voltage, motor insulation, 120 Ohm termination resistors on the CAN bus, and correct seating of any installed AIF module. If the drive displays persistent internal hardware errors such as H05 or unrecoverable EER memory corruption, internal board repairs or exchange units supplied by ABC Industrial Parts offer a practical solution to restore machine uptime.

Programming and Configuration
Parameter management for the Lenze EVF9324-EV frequency inverter is conducted using the optional Keypad XT EMZ9371BC operator module or Lenze Global Drive Control (GDC) software version 4.x and higher. The internal non-volatile EEPROM memory maintains up to four independent parameter sets, allowing operators to switch configuration profiles for different operating modes or production recipes without reloading drive firmware.
When uploading or downloading drive configurations via a PC connected through a system bus adapter, GDC software provides full visibility into drive registers, functional block structures, and status parameters. Before placing a replacement inverter into service, all application parameters—including motor nameplate values, acceleration/deceleration ramps, speed limits, and digital I/O mapping—must be saved from the existing unit or active backup project file and written to the spare drive to ensure proper process synchronization.
Communication and System Integration
The EVF9324-EV drive incorporates an onboard CAN System Bus interface capable of transmission speeds up to 500 kbit/s. This integrated network connection allows rapid inter-drive coordination, speed synchronization, and real-time control data exchange across multi-axis machines without requiring additional gateway hardware. Proper network operation relies on maintaining correct baud rate settings and attaching 120 Ohm bus termination resistors at both physical ends of the CAN network cable.
For integration into higher-level industrial networks, the inverter features a dedicated Automation Interface (AIF) expansion slot. This slot accommodates plug-in fieldbus modules including EMF2133IB and EMF2102IB PROFIBUS-DP interfaces as well as LECOM RS232/RS485 adapters. The master controller monitors communication state over the AIF slot, generating diagnostic alerts if module seatings loosen or cabling drops out.
Diagnostics and Status Indication
The drive provides status indication via three LEDs mounted on the unit: the green RUN LED indicates enabled operation, the yellow IMP LED signals pulse inhibit state, and the red TRIP LED illuminates when a drive fault occurs. Supplemental diagnostics are accessed via the Keypad XT display panel or through GDC engineering software, which accesses the drive's internal diagnostic register history in memory parameters C0161 through C0164.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| TRIP | Red - Active | Fault message active / drive tripped. Internal fault, overcurrent, overvoltage, or thermal trip. |
| RUN | Green - Active | Inverter enabled and operating / ready for operation. |
| IMP | Yellow - Active | Pulse inhibit active / controller inhibit. |
Replacement and Spare Part Considerations
Replacing an installed Lenze 9300 Vector EVF9324-EV inverter requires strict verification of hardware ratings and software configurations. The replacement unit must share the 11 kW power rating and 23.5 A continuous output current capacity to match motor requirements. Maintenance personnel should also confirm that any external fieldbus card, such as an EMF2133IB PROFIBUS-DP module, is transferred from the old unit to the AIF slot of the new drive.
Because new or factory-default spare drives do not contain machine-specific application settings, parameter profiles must be loaded prior to enabling the motor. Parameters can be cloned directly using the Keypad XT module's transfer function or written over the system bus using GDC software. Additionally, field technicians must verify that CAN bus address switches, baud rate configurations, and terminal jumper settings match the original unit prior to applying power.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short circuit / Overcurrent | Instantaneous short circuit or heavy overcurrent at output terminals. | Short circuit in motor cable or motor winding; excessive acceleration rate; drive size too small. | Check motor cable and motor insulation; increase acceleration time; check drive output stage. If error persists with motor disconnected, internal hardware fault requires unit repair. |
| OC2 | Earth fault | Ground fault / earth leakage current detected. | Earth fault in motor or motor cable; ground leakage capacitance too high. | Check motor and motor cable for ground fault; check cable length limitations. |
| OC5 | Ixt overload | Continuous device overload (I x t protection limit reached). | Drive continuously operated above rated current; mechanical overload; duty cycle too heavy. | Reduce motor load; check mechanical system for binding; review load profile. |
| OU | Overvoltage DC bus | Intermediate circuit DC voltage exceeded maximum threshold. | Regenerative energy during deceleration too high; deceleration time too short; brake chopper failure or missing brake resistor. | Increase deceleration time (down ramp); connect braking resistor / check brake chopper module. |
| LU | Undervoltage DC bus | DC bus voltage dropped below minimum operating limit. | Mains supply voltage too low; phase failure in mains line; power supply interruption. | Check mains voltage and supply line fuse/switches. |
| OH | Heatsink overtemperature | Heatsink temperature exceeded upper limit (> 90 °C). | Insufficient cooling airflow; ambient temperature too high; fan defective or clogged heatsink. | Clean heatsink cooling fins; verify cooling fan operation; ensure adequate cabinet ventilation. |
| OH4 | Motor overtemperature | Motor thermal sensor or PTC contact opened. | Motor thermal overload; PTC thermistor tripped; thermal contact wiring broken. | Allow motor to cool down; check motor loading; check PTC thermistor wiring on terminals T1/T2. |

| EER | EEPROM memory error | Error reading or writing data in non-volatile internal memory. | EEPROM corrupted; power loss during parameter save operation; hardware memory defect. | Reload factory default parameters and reconfigure. If fault cannot be cleared, internal board hardware fault — return unit for repair. |
