Product Information
The Lenze EVF9325-EV frequency inverter, designated by part number 13432619, is a 5.5 kW drive unit within the Lenze 9300 Vector series designed for precise speed and torque control in automated production environments. Operating across a 3-phase supply voltage range of 320 V AC to 528 V AC, this compact IP20-rated drive supplies a continuous current of 13 A at 400 V AC (11 A at 480 V AC) and delivers a maximum peak output current of 19.5 A with a 150% overload capacity for up to 60 seconds. The unit supports versatile control methods including sensorless vector control, torque control, and programmable V/f characteristics over an output frequency range of 0 Hz to 480 Hz with an 8 kHz switching frequency, making it suitable for material handling conveyors, industrial fans, pumps, packaging machinery, and agitators requiring robust startup performance.
System integration and control wiring are facilitated through six 24 V DC digital inputs, two digital outputs, two bipolar analog inputs (-10 V to +10 V or 4-20 mA), and two analog outputs alongside terminal X1 TRIP relay contacts. For network communication, the drive features an onboard CAN system bus supporting transfer rates up to 500 kbit/s for motion synchronization between drives. A modular Automation Interface (AIF) slot accepts optional communication modules, including PROFIBUS-DP (EMF2133IB / EMF2131IB), LECOM RS232/RS485 (EMF2102IB / EMF2111IB), or an interactive Keypad XT (EMZ9371BC) display. Internal non-volatile EEPROM memory stores up to four independent parameter sets, allowing engineers to back up drive settings or transfer complete program profiles using Lenze Global Drive Control (GDC) software or the plug-in keypad. When replacing a unit, matching parameter configurations and transferring settings from the old drive is essential before putting the spare into service, a process where technical support from ABC Industrial Parts can assist in ensuring operational readiness.
Drive operation and active operating states are indicated on the front panel via three diagnostic LEDs: Green (Ready / Controller enable), Yellow (IMP / Warning pulse inhibit), and Red (TRIP / Fault state). System technicians can inspect the integrated fault history buffer across parameters C0161 to C0164 using Keypad XT or GDC software to identify specific active or historical fault codes such as overvoltage (OU), undervoltage (LU), phase failure (LP1), overcurrent (OC1, OC2, OC5), and overtemperature conditions (OH, OH4, OH7). Diagnostic checks should begin by verifying line supply voltages across L1, L2, and L3, checking motor winding insulation, verifying AIF module seating, and confirming proper 120-ohm CAN bus termination. In situations involving internal component degradation, fan failure (H10), or memory corruption (EER), internal hardware faults are not field-serviceable, making drive repair or a fully tested exchange replacement unit from ABC Industrial Parts the most reliable path back to production.

Programming and Configuration
The Lenze EVF9325-EV is configured using Lenze Global Drive Control (GDC) engineering software or the portable Keypad XT module (EMZ9371BC). Drive parameters control speed ramps, current limits, control modes, and I/O assignments across the frequency inverter's operating ranges.
An onboard non-volatile EEPROM retains up to four complete, independent parameter sets without requiring continuous battery backup. This feature enables rapid profile switching and allows maintenance personnel to clone functional drive configurations directly to donor hardware during field maintenance.
Standard factory default settings can be restored by setting parameter C0002 to value 1 via the keypad or GDC software interface. Following a factory reset, custom motor data, application settings, and fieldbus parameters must be reloaded to re-establish machine control.
Communication and System Integration
Drive-to-drive motion control and distributed automation are supported through an integrated CAN system bus operating at speeds up to 500 kbit/s. Terminal connections facilitate multi-axis drive synchronization and high-speed data exchange using CAN/CANopen protocols.
The modular Automation Interface (AIF) slot on the front housing accepts optional communication adapters to integrate with various fieldbus networks. Supported options include PROFIBUS-DP modules (EMF2133IB / EMF2131IB) and LECOM RS232/RS485 interfaces (EMF2102IB / EMF2111IB), enabling communication with central PLCs or higher-level control systems.
Diagnostics and Status Indication
Operational states and system faults are displayed locally on the inverter housing using three status LEDs. The Green LED remains solid when power is applied and controller enable is active. The Yellow LED indicates a pulse inhibit state or warning condition, while a solid or blinking Red LED indicates an active TRIP condition with drive outputs disabled.
Advanced troubleshooting is conducted by accessing the fault history buffer (parameters C0161 to C0164) through Keypad XT or GDC software. The TRIP relay contact on terminal X1 provides a physical dry-contact output to signal external PLC logic when an alarm condition occurs.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid / Blinking | Fault/Error state active. Drive output is inhibited (TRIP state). Blinking indicates specific fault conditions or warning state. |
| Green LED (Ready) | Green - Solid | Drive is powered and operational (Ready / Controller enable). Normal operating mode with pulses enabled. |
| Yellow LED (IMP / Warning) | Yellow - Solid | Pulse inhibit active / Warning condition present. Output power stage is locked. |
Replacement and Spare Part Considerations
When replacing an existing EVF9325-EV drive (part number 13432619), the replacement unit must match the voltage rating (320–528 V AC) and continuous output current capacity (13 A at 400 V AC) of the original unit. Ensure that any installed AIF fieldbus communication module or Keypad XT display is transferred from the old drive to the replacement housing's AIF slot.
Parameter sets stored in the original inverter's EEPROM should be downloaded using GDC software or saved to a Keypad XT module prior to swapping hardware. After installing the replacement unit, parameter data must be written to the drive's memory to ensure proper motor tuning, I/O terminal functions, and network node settings before enabling system operation.
