Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13324685 (model EVF9325-EV) is a cabinet-mounted frequency inverter belonging to the Lenze 9300 Vector drive family. Rated for 5.5 kW output power, this drive is engineered to control 3-phase standard AC motors across applications such as continuous conveyor systems, torque-controlled winding machines, and process pumps or fans. Operating on a 3-phase supply voltage range from 320 to 528 V AC, the inverter delivers a continuous output current of 13 A at an 8 kHz switching frequency, with an output frequency range of 0 to 480 Hz. Designed for high dynamic performance, it supports sensorless vector control, V/f characteristic control, and torque control modes, while providing an overload capacity of 150% (19.5 A) for up to 60 seconds to manage heavy starting torque requirements.
Connecting and installing the EVF9325-EV within a control cabinet is facilitated by detachable terminal headers, allowing swift drive swaps without rewiring individual terminal leads. The drive features six digital inputs, four digital outputs, two selectable analog inputs (-10V to +10V, 0-10V, 4-20mA), and two analog outputs. An integrated CAN system bus interface enables multi-drive synchronization, while a pluggable Automation Interface (AIF) slot accepts optional communication modules for PROFIBUS-DP or INTERBUS fieldbus integration. Bringing a spare unit into service requires matching the installed fieldbus module and reloading the application parameters. Up to four complete parameter sets are stored in non-volatile internal EEPROM memory, which can be configured or backed up using Global Drive Control (GDC) engineering software or an XT Keypad (EMF2171IB). Technical assistance for parameter extraction or selecting suitable replacement units is available through ABC Industrial Parts.
Operational status and troubleshooting are indicated directly on the front panel via LED indicators, including a solid green READY LED for active operation, a solid yellow IMP LED for pulse inhibit, and a solid red TRIP LED indicating an active fault condition that disables the inverter output stage. The drive maintains a fault history memory of the last eight events with timestamps, accessible through the XT Keypad panel, GDC software monitor, or CAN bus registers. Common field alarms include input undervoltage (LU), DC bus overvoltage (OU), overcurrent (OC1), or heatsink overtemperature (OH), which can generally be addressed by verifying line supply voltages, deceleration times, motor wiring, and cabinet ventilation. Internal hardware errors—such as power stage fault (H05), temperature sensor failure (OH7), EEPROM checksum fault (EER), or program execution error (PER)—cannot be serviced in the field, making drive repair or a tested exchange unit from ABC Industrial Parts the recommended solution to restore production quickly.

Programming and Configuration
Programming and parameter administration for the Lenze 13324685 EVF9325-EV are managed using Lenze Global Drive Control (GDC) software or the plug-in XT Keypad (EMF2171IB). The drive contains integrated non-volatile EEPROM memory capable of holding up to four complete parameter sets. Using the XT Keypad panel, maintenance engineers can clone parameter profiles directly from an existing drive and upload them into a replacement unit in under two minutes, eliminating manual data entry during changeouts.
When using GDC software, connection to the inverter is established via the CAN system bus interface or through an RS-232 serial module inserted into the Automation Interface slot. GDC provides comprehensive setup parameters for tuning motor control algorithms, adjusting acceleration and deceleration ramps, defining digital I/O function assignments, and setting signal scaling for the analog inputs and outputs. If a parameter write operation is interrupted or memory becomes corrupt, the drive issues a parameter initialization fault (PI), requiring a parameter restore from a known backup file or a reset to factory default values.
Communication and System Integration
The Lenze EVF9325-EV incorporates an integrated CAN system bus interface designed for high-speed inter-drive communication and controller integration. This interface allows real-time speed, torque, and status synchronization across multiple 9300 Vector drives without requiring additional fieldbus hardware. Physical connection is made through dedicated terminal blocks, requiring proper 120-ohm bus termination resistors at both physical ends of the network to maintain noise-free signal transmission.
For higher-level network integration, the inverter features a pluggable Automation Interface (AIF) slot on the front fascia. This slot accepts optional network interface cards, including PROFIBUS-DP modules (EMF2133IB or EMF2131IB) and INTERBUS modules (EMF2111IB). Detachable control terminal headers simplify physical wiring, allowing control signals—including the six digital inputs, four digital outputs, two analog inputs, and two analog outputs—to remain wired during component replacement.
Diagnostics and Status Indication
The EVF9325-EV frequency inverter provides immediate visual status monitoring through three dedicated front-panel LEDs. A solid green READY LED confirms the controller is powered and ready for operation. A solid yellow IMP LED indicates that pulse inhibit is active and the inverter output stage is disabled. A solid red TRIP LED signals that a protective drive shutdown has occurred, cutting power to the motor output terminals until the fault condition is resolved and reset.
Advanced diagnostic monitoring is supported through the XT Keypad (EMF2171IB) display panel, the GDC software diagnostic monitor, and CAN system bus diagnostic registers. The inverter maintains an internal fault memory buffer storing the eight most recent fault codes along with time records. This buffer enables technicians to trace transient trip events, such as intermittent overvoltage spikes or thermal overloads, to determine root operational causes.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| TRIP | Red - Solid | Drive fault state active (TRIP mode). Inverter output disabled due to fault condition. |
| READY | Green - Solid | Drive controller ready for operation / active operation. |
| IMP | Yellow - Solid | Pulse inhibit active (output stage disabled / controller inhibited). |
Replacement and Spare Part Considerations
Replacing a legacy Lenze 13324685 EVF9325-EV frequency inverter in an existing cabinet is straightforward due to its direct drop-in mechanical design and detachable terminal block system. When swapping a unit, control and power wiring harnesses can remain intact, minimizing physical installation time and avoiding wiring sequence errors.
Before putting a spare EVF9325-EV unit into service, ensure that any optional Automation Interface card (such as a PROFIBUS EMF2133IB/EMF2131IB or INTERBUS EMF2111IB module) is transferred from the old drive to the spare unit's AIF slot. Following physical installation, parameter sets must be loaded into the replacement drive via the XT Keypad or GDC software to match motor nameplate data, dynamic ramp settings, and communication node addresses before enabling system operation.
