Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00408454 (EVS9325-ES) is a 5.5 kW AC servo drive belonging to the 9300 Servo Inverters family, designed for precise speed, torque, and motion control applications. Operating on a 3-phase supply voltage ranging from 320 V AC to 528 V AC at 45 to 65 Hz, the unit provides a continuous rated output current of 13 A at an 8 kHz switching frequency. For highly dynamic operations, it supports a peak output current of 19.5 A (150% overload) for up to 60 seconds. Utilizing advanced field-oriented vector control, the drive is suitable for both permanent magnet synchronous motors and asynchronous AC motors. Embedded application software modules handle point-to-point positioning, electronic gearing, and dynamic motion sequences directly, reducing the processing burden on higher-level automation controllers.
System connectivity and signal integration on the EVS9325-ES include a dedicated 9-pin resolver feedback connection, master frequency/encoder simulation inputs and outputs, five digital inputs, four digital outputs, two analog inputs, and two analog outputs. Multi-axis drive synchronization is handled via an onboard CAN system bus operating at communication speeds up to 500 kbit/s. An integrated Automation Interface (AIF) slot accommodates expansion options, including PROFIBUS DP (EMF2133IB), INTERBUS (EMF2111IB), RS232 LECOM (EMF2101IB), or the pluggable Keypad XT (EMF2102IB). Putting a replacement drive into service requires parameter alignment, as up to four complete parameter sets are retained in non-volatile internal memory. Configuration files can be transferred using Lenze Global Drive Control (GDC) software V4.x+ or a Keypad XT module. Technical specialists at ABC Industrial Parts can support parameter backup and verification to help ensure a smooth replacement process.
Monitoring and diagnostic routines are facilitated by three status LEDs on the unit—DRIVE READY (green), TRIP (red), and IMP/Warning (yellow)—alongside internal CAN diagnostic registers and software status codes. Common operational warnings and fault conditions include DC bus overvoltage (OU), undervoltage (LU), mains phase failure (LP1), heatsink overtemperature (OH), and CAN bus communications errors (CE1). Field maintenance teams can perform initial checks on mains voltage terminals, resolver wiring, motor insulation, and bus termination resistors. When internal self-tests indicate unrecoverable control hardware errors (H05) or EEPROM memory faults (H10), internal circuit boards are not field-serviceable. In these cases, securing a tested replacement drive or opting for expert repair through ABC Industrial Parts provides a direct solution to restore machinery operation.

Programming and Configuration
The Lenze EVS9325-ES servo inverter utilizes software-based commissioning tools to set up motion routines, control parameters, and fieldbus communication settings. Primary engineering is performed via Lenze Global Drive Control (GDC) software version 4.x or higher, which connects to the drive via an RS232 LECOM module or suitable adapter interface. Alternatively, basic parameter adjustments, status monitoring, and fault log reviews can be carried out locally using the optional pluggable Keypad XT (EMF2102IB).
Internal drive memory stores up to four separate non-volatile parameter sets, enabling multi-recipe machine operations or simple configuration backups. Embedded application software routines handle key motion functions, including absolute positioning control, electronic gearbox synchronization, and configurable speed or torque loops. When commissioning or swapping drives, engineers must write valid parameter sets matching the specific motor feedback profiles, thermal protection thresholds, and system gear ratios.
Communication and System Integration
System integration with the EVS9325-ES centers around its integrated CAN system bus interface. Supporting transmission speeds up to 500 kbit/s, the CAN bus enables real-time synchronization between multiple drives in multi-axis setups without requiring additional interface hardware. The bus manages motion commands, cyclic encoder data sharing, and remote parameter updates directly across the network.
To interface with centralized industrial communication networks, the drive includes a modular Automation Interface (AIF) slot. This slot supports various fieldbus options, including PROFIBUS DP (EMF2133IB), INTERBUS (EMF2111IB), and RS232 LECOM modules (EMF2101IB). Additional signal terminals provide five digital inputs, four digital outputs, two analog inputs, two analog outputs, a 9-pin resolver input connection, RS422 encoder simulation outputs, and master frequency inputs.
Diagnostics and Status Indication
The EVS9325-ES features three status LEDs located on the front panel to provide immediate visual feedback regarding drive operating state and fault conditions. Supplementary diagnostic data, including historical fault logs and real-time internal bus registers, can be accessed using the Keypad XT display module or the GDC software diagnostic monitor.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY / Operation | Green - Solid / Blinking | Glowing solid indicates power stage enabled and drive ready for operation. Blinking indicates controller inhibit or pulse inhibit active. |
| TRIP | Red - Solid / Flashing | Active TRIP fault condition present. Power stage is disabled due to a fault. |
| IMP / Warning | Yellow - Solid / Flashing | Pulse inhibit active or warning threshold / current limit reached. |
Replacement and Spare Part Considerations
Replacing an existing Lenze EVS9325-ES drive requires transferring both hardware options and parameter data to the replacement unit. Ensure the new unit matches the same power rating (5.5 kW) and standard 320–528 V AC operating range. The optional Automation Interface (AIF) module—such as PROFIBUS DP (EMF2133IB) or INTERBUS (EMF2111IB)—must be unclipped from the existing drive and securely installed into the AIF slot on the replacement unit.
Because the EVS9325-ES relies on specific application parameter sets stored in internal non-volatile EEPROM memory, a factory-default replacement drive will not operate the machine without configuration. Before powering up the replacement in production, upload the saved parameter backup using Global Drive Control (GDC) software V4.x+ or transfer the configuration using a Keypad XT (EMF2102IB) module. Verify that node addresses, CAN bus baud rates, and motor feedback parameters match the original installation.

Frequently Asked Questions
What software is required to configure the Lenze EVS9325-ES?
The drive is configured using Lenze Global Drive Control (GDC) software version 4.x or higher, connected via an RS232 LECOM module (EMF2101IB). Parameter adjustments and diagnostic monitoring can also be performed using the Keypad XT module (EMF2102IB).
Can I swap an EVS9325-ES unit without transferring software parameters?
No. A replacement drive contains factory-default settings and must be configured with the application parameter set using GDC software or a Keypad XT module before it will run in the machine.
What does a solid red TRIP LED mean on the EVS9325-ES?
A solid red TRIP LED indicates an active fault condition that has disabled the drive power stage. Specific fault codes such as OC1 (short circuit), OU (overvoltage), or OH (overtemperature) must be investigated via the Keypad XT display or GDC software.
How is multi-axis drive synchronization achieved with this model?
Multi-axis synchronization is handled via the onboard CAN system bus interface operating at speeds up to 500 kbit/s, removing the need for external motion synchronization cards.
What should I do if the drive displays an H05 fault code?
Fault code H05 indicates an internal hardware failure on the control or power board. This condition is not field-serviceable, requiring the unit to be repaired or replaced.
