Product Information
The Lenze 00488200 EVF9324-EV is a 2.2 kW (3 HP) AC frequency inverter from the 9300 Vector product family, engineered for dynamic speed and torque control of 3-phase asynchronous AC motors. Operating from a 3-phase 400 V AC supply, this drive delivers a continuous rated output current of 5.9 A with an output frequency range from 0 Hz to 480 Hz. Designed to handle demanding mechanical loads in applications such as conveying systems, industrial fans, pumps, and packaging machinery, it features a 150% overload capability supporting up to 8.9 A output current for 60 seconds. The drive provides precise speed regulation through either open-loop V/f characteristic control or sensorless vector control, backed by an efficient power stage operating at an 8 kHz switching frequency with a power loss rating of 110 W.
System integration and field communications are handled via an onboard CAN system bus interface supporting communication speeds up to 500 kbit/s, alongside a front Automation Interface (AIF) slot. This modular expansion slot accommodates fieldbus modules such as the PROFIBUS-DP module (EMF2133IB), LECOM RS232/RS485 adapters (EMF2102IB and EMF2101IB), DeviceNet, and INTERBUS, as well as the optional Keypad XT (EMZ9371BC). The physical control interface features four digital inputs, two digital outputs, two bipolar analog inputs, two analog outputs, and one changeover relay contact. Commissioning a replacement unit requires restoring parameter profiles stored in non-volatile internal EEPROM, which holds up to four parameter sets transferable using the Lenze Global Drive Control (GDC) V4.x+ software or the pluggable Keypad XT. Technical support from ABC Industrial Parts can assist maintenance teams with parameter extractions and unit preparation prior to installation.
Diagnostic status is indicated on the front face through three dedicated LEDs: Ready (Green) for operational and inhibit state, IMP (Yellow) for active pulse inhibit, and TRIP (Red) for active faults and warnings. Fault conditions can be interrogated directly via the Keypad XT fault memory, through diagnostic parameters C0003, C0161, and C0168 over the CAN system bus or LECOM interface, or by monitoring the TRIP relay contact on terminals 11-12-14. When encountering persistent power stage hardware faults (H05), system program exceptions (PR0), or internal memory errors (EEr), internal component failures are not field-serviceable. In these situations, replacing the unit with a tested exchange drive from ABC Industrial Parts offers the most efficient solution to restore operational uptime.

Programming and Configuration
Programming and parameter management for the Lenze EVF9324-EV are performed through Lenze Global Drive Control (GDC) software version 4.x or higher, connected via LECOM RS232/RS485 adapters or system bus interfaces. The drive architecture utilizes customizable function block logic, incorporating integrated PID controllers, configurable ramp generators, and flexible fieldbus mapping to align with application requirements.
For local parameter modification and transfer without a computer, the Keypad XT (EMZ9371BC) attaches to the front Automation Interface slot. Non-volatile internal EEPROM memory stores up to four complete parameter sets. Maintenance personnel can load default factory settings using parameter C0002 and execute parameter saves across memory channels, enabling quick configuration backup and transfer between drives during routine servicing or emergency replacements.
Communication and System Integration
The EVF9324-EV includes an integrated CAN system bus connected at terminal X4, operating at data rates up to 500 kbit/s. This interface allows multi-drive synchronization and direct networking with host controllers across automated production equipment. Proper bus topology requires 120-ohm termination resistors at both line ends and correct node address assignment to prevent communication interrupts.
Broader industrial network connectivity is achieved through the front Automation Interface (AIF) slot. The drive supports optional fieldbus modules including PROFIBUS-DP via the EMF2133IB interface card, DeviceNet, INTERBUS, and serial LECOM RS232/RS485 modules (EMF2101IB and EMF2102IB). Physical control I/O includes four digital inputs, two digital outputs, two analog inputs, two analog outputs, and a single relay output contact.
Diagnostics and Status Indication
Real-time diagnostic feedback is provided through three status LEDs located on the drive front panel. System status and active fault conditions can also be interrogated using the Keypad XT module display or by accessing diagnostic parameters C0003, C0161, and C0168 over LECOM or CAN bus interfaces. Terminal contacts 11, 12, and 14 provide a hardware TRIP relay signal for safety circuit interlocks.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Solid / Fast Flashing / Slow Flashing | Continuous light = Drive operational / pulses enabled. Fast flashing = Controller inhibit active. Slow flashing = Drive in stop/ready state. |
| IMP | Yellow - Solid | Continuous light = Pulse inhibit active (drive power section disabled). |
| TRIP | Red - Solid / Flashing | Continuous light = Fault/TRIP active (drive shut down due to active error). Flashing = Warning active. |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVF9324-EV drive, match part number 00488200 and model code to ensure supply voltage and current ratings match the application. Before applying power to the replacement unit, copy the target parameter sets stored in the internal EEPROM of the original drive using either the pluggable Keypad XT module or Lenze GDC software.
Ensure optional AIF communication cards, such as PROFIBUS-DP or LECOM modules, are transferred to the replacement unit and correctly seated in the front expansion slot. Control terminal wiring at X10, CAN system bus connections at X4, and power supply cabling on L1, L2, and L3 should be verified. When migrating machinery to current hardware, modern replacement options include the Lenze i550 cabinet frequency inverter series.
