Product Information
The Lenze 00450922 EVS9325-ES is a 5.5 kW servo inverter from the Lenze 9300 Servo family, engineered for precise speed, positioning, and torque regulation in automated packaging, printing, textile, and material handling systems. Operating on a three-phase AC input supply ranging from 320 V to 528 V AC at 48 to 62 Hz, this unit delivers a continuous rated output current of 13.0 A at up to 480 V AC. It provides an overload capacity of 19.5 A (150% rated current for up to 60 seconds) to handle peak torque requirements during rapid motor acceleration. Utilizing field-oriented vector control, the inverter achieves dynamic motor regulation across an output frequency range of 0 Hz to 480 Hz with an 8 kHz switching frequency.
For position and speed feedback, the unit features built-in Sub-D interface connectors for resolvers and TTL incremental encoders, as well as a frequency emulation output for multi-axis master-slave synchronization. System integration is enabled by an integrated CAN system bus operating at up to 500 kbit/s, along with a modular XT expansion slot that accommodates optional fieldbus modules such as PROFIBUS-DP (EMF2133IB), CANopen (EMF2175IB), DeviceNet (EMF2173IB), or INTERBUS (EMF2103IB). Commissioning a replacement unit requires transferring application data, as internal non-volatile EEPROM memory holds up to four complete parameter sets. Parameter backup and transfer are managed using the EMZ9371BC plug-in operating keypad module or Lenze Global Drive Control (GDC) PC software, with assistance available through ABC Industrial Parts for parameter extraction and software setup.
Operating state and fault conditions are visible on the front panel via three diagnostic LEDs: a solid green DRIVE READY indicator for normal operation with controller enable active, a solid yellow IMP / Inhibit indicator when pulse inhibit is active, and a solid red TRIP / FAULT LED indicating an active fault condition where the power stage is disabled. Detailed fault history and drive status variables are logged in the C0168 parameter buffer. Initial field troubleshooting should focus on line supply voltage, motor cable insulation, thermal cooling paths, and bus line termination. When unrecoverable board-level faults occur, such as code H05 internal hardware failure or EE0 memory corruption, internal repairs cannot be performed on site, making a tested replacement unit or repair service from ABC Industrial Parts the recommended solution to restore operation.

Programming and Configuration
The Lenze EVS9325-ES servo inverter relies on non-volatile EEPROM storage capable of retaining up to four complete parameter sets. Drive setup, motion profiles, scaling factors, and system functions are configured using either the plug-in EMZ9371BC operating keypad module or Lenze Global Drive Control (GDC) PC software. When commissioning a spare drive, transferring the active parameter set ensures identical performance without re-entering application parameters manually.
During replacement, communication parameters such as baud rate (parameter C0003) and CAN node ID (parameter C0009) must match the network setup of the machine PLC. If a parameter set becomes corrupt, the full drive profile can be restored via GDC software or reset to factory defaults. For units suffering from non-responsive control boards, component-level parameter extraction from electronic storage on a donor board can facilitate data recovery prior to installing a replacement unit.
Communication and System Integration
Network integration is built directly into the EVS9325-ES through an integrated CAN system bus operating at speeds up to 500 kbit/s. This peer-to-peer connection enables rapid multi-axis synchronization directly between drives without requiring central motion controllers or external gateway hardware. The unit also offers physical control interfaces including 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs for direct wiring to switches, sensors, and analog reference signals.
Higher-level fieldbus communication is achieved using the modular XT expansion slot located on the drive front. This slot supports optional communication modules including the EMF2133IB for PROFIBUS-DP, EMF2175IB for CANopen, EMF2173IB for DeviceNet, and EMF2103IB for INTERBUS. Proper network operation requires installing 120-Ohm bus termination resistors at the ends of the CAN communication cable and ensuring the XT module is firmly seated in its slot.
Diagnostics and Status Indication
Drive status and fault diagnostics on the EVS9325-ES are monitored through front panel LEDs and real-time internal drive parameters. The inverter tracks operating metrics including DC bus voltage, output current, motor speed, and heatsink temperature. Fault events and history records are logged in the C0168 parameter buffer, accessible via the EMZ9371BC keypad or GDC software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid | Operational state indicator; lit solid when drive is ready for operation and controller enable is active. |
| TRIP / FAULT | Red - Solid | Active fault condition present; power stage is inhibited. If lit permanently with no clear external fault, signals potential internal hardware failure requiring service or unit replacement. |
| IMP / Inhibit | Yellow - Solid | Pulse inhibit active; power output stage is disabled by controller enable signal or internal protection. |
Replacement and Spare Part Considerations
When selecting a replacement for a Lenze 00450922 EVS9325-ES, ensure that the power rating (5.5 kW) and continuous current rating (13.0 A) match the existing drive specification. Installing a replacement drive requires transferring the active parameter set using the EMZ9371BC keypad module or GDC software, as well as moving any installed XT communication module (e.g., PROFIBUS or CANopen) to the spare drive.
Before applying power, verify that communication settings, including CAN node ID (C0009) and baud rate (C0003), align with system controller requirements. For long-term migration planning, Lenze offers the i700 and i950 servo inverter lines as modern successor series, though direct drop-in replacement on legacy cabinets requires reviewing parameter structure and mechanical installation.

Frequently Asked Questions
How do I transfer parameters to a replacement Lenze EVS9325-ES drive?
Parameter profiles stored in the drive's EEPROM can be transferred to a replacement unit by attaching the plug-in EMZ9371BC operating keypad or by connecting a PC running Lenze Global Drive Control (GDC) software to upload and restore the saved configuration.
What optional fieldbus modules fit the EVS9325-ES expansion slot?
The EVS9325-ES features an XT automation slot that supports optional modules including EMF2133IB for PROFIBUS-DP, EMF2175IB for CANopen, EMF2173IB for DeviceNet, and EMF2103IB for INTERBUS.
What does a solid red TRIP / FAULT LED mean on the drive front panel?
A solid red TRIP / FAULT LED indicates an active trip condition that has inhibited the inverter power stage. If the LED remains lit solid and no external wiring, load, or power issues are detected, it points to an internal hardware defect, such as error code H05 or EE0.
