Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9330-ESV004 is a panel-mounted 45 kW servo inverter from the Lenze 9300 series (model designation EVS9330-ES), engineered to deliver field-oriented vector control for both synchronous and asynchronous AC servo motors. Providing a continuous output current of 89 A at a 4 kHz switching frequency within an IP20 enclosure, this unit enables precise torque management and velocity control in multi-axis industrial motion applications. The V004 configuration designates an integrated Safe Stop hardware safety function, allowing safe power disconnection without requiring external safety contactors.
Operating on a three-phase supply range of 320 V AC to 528 V AC (45 to 65 Hz), the drive features standard physical connections including a SUB-D interface for resolver feedback on input X8, master frequency input and output connections, and an integrated CAN System Bus supporting CANopen protocols. System expansion is managed via Automation Slot A, which supports option modules for PROFIBUS-DP (EMF2133IB/EMF2131IB), DeviceNet (EMF2177IB/EMF2174IB), and INTERBUS (EMF2113IB/EMF2111IB). Commissioning a replacement unit requires restoring the machine's parameter profile, which can be loaded from non-volatile EEPROM storage using the optional XT Keypad (EMF2102IB) or via Lenze Global Drive Control (GDC) software. Preparing a replacement unit through ABC Industrial Parts ensures proper parameter alignment and interface verification prior to installation.
Front-panel status indication is provided by three color LEDs showing operational readiness, active pulse inhibit/current limit, and fault status. The internal controller stores the four most recent TRIP events in a dedicated fault history memory buffer, accessible through the XT Keypad, GDC software, or CANbus registers. External faults caused by supply disturbances or feedback disconnects can be resolved through external checks, but internal errors such as hardware failures or memory corruption require hardware-level repair or complete drive replacement. When internal board faults bring production to a halt, sourcing a fully tested exchange unit or repair option through ABC Industrial Parts provides a direct route back to operation.

Programming and Configuration
Configuration and parameter setup for the Lenze EVS9330-ESV004 are executed using Lenze Global Drive Control (GDC) software or directly via the pluggable XT Keypad (EMF2102IB) connected to Keypad Slot X6. The drive contains non-volatile EEPROM memory capable of retaining up to four independent parameter sets, allowing versatile control scheme switching or straightforward backup creation.
When commissioning a replacement drive, parameters can be cloned directly from the internal EEPROM of a configured unit using the XT Keypad without requiring a PC connection. Alternatively, parameter sets can be uploaded and downloaded over the system bus using GDC software connected via a PC system bus adapter.
Communication and System Integration
The EVS9330-ESV004 features a built-in CAN System Bus interface supporting CANopen protocols for real-time motion control coordination and parameter exchange across multi-axis networks. In addition to system bus communication, the drive offers master frequency input and output interfaces for drive synchronization and position feedback.
Fieldbus connectivity is achieved through modular option cards installed in Automation Slot A. Compatible communication modules include PROFIBUS-DP (EMF2133IB / EMF2131IB), DeviceNet (EMF2177IB / EMF2174IB), and INTERBUS (EMF2113IB / EMF2111IB). When replacing a unit, the installed fieldbus module can be unclipped and transferred directly to the spare drive.
Diagnostics and Status Indication
The front panel of the EVS9330-ESV004 includes three status LEDs that provide visual operational diagnostics. The drive also logs diagnostic parameters across CANbus registers and maintains a fault history memory buffer storing details of the last four TRIP events.
Detailed parameter inspection and fault log analysis can be conducted on-site using the LCD display of the XT Keypad (EMF2102IB) or remotely via Global Drive Control (GDC) software over the system bus interface.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid | Inverter fault / TRIP state active; output stage disabled. |
| Green LED (Ready) | Green - Blinking / Solid | Inverter power stage ready for operation (blinking = standby, solid = enabled/operating). |
| Yellow LED (IMP / Current limit) | Yellow - Solid / Flashing | Pulse inhibit active or motor current limit reached. |
Replacement and Spare Part Considerations
When selecting a replacement unit for the EVS9330-ESV004, ensure the part number matches the V004 suffix, which indicates integrated Safe Stop hardware capability. Installing a standard variant without Safe Stop will cause safety circuit incompatibilities and prevent machine operation.
Before placing a replacement unit into service, transfer any option modules installed in Automation Slot A (such as PROFIBUS or DeviceNet cards) and restore the original parameter set using an XT Keypad or Global Drive Control software. For new machine designs or long-term plant modernization, the Lenze i950 cabinet servo drive series is recommended as a modern replacement path.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit / Overcurrent | Instantaneous overcurrent in inverter power output stage. | Short circuit in motor windings or motor cable; acceleration time too short; motor insulation failure. | Check motor and motor cable for phase-to-phase or phase-to-ground short circuit; increase acceleration ramp times. |
| OC2 | Earth Fault | Ground fault / earth current detected on inverter output. | Earth fault in motor lead or motor winding. | Check motor wiring and motor insulation resistance to earth. |
| OC5 | I x t Overload | Continuous overload threshold reached (inverter thermal load limit exceeded). | Inverter operated under continuous overload conditions beyond rated continuous output current. | Check drive sizing against load profile; reduce continuous motor current demand. |
| OU | DC Bus Overvoltage | DC bus link voltage exceeded upper safety threshold (>770 V DC). | Excessive braking energy regenerated into DC bus; braking resistor defective or disconnected; deceleration ramp too steep. | Increase deceleration ramp time; check braking resistor connection and chopper resistor function. |

Frequently Asked Questions
What is the significance of the V004 designation on the Lenze EVS9330-ESV004?
The V004 designation indicates that the servo drive is equipped with an integrated Safe Stop safety function. This integrated hardware safety feature allows safe power disconnection according to safety standards without requiring external safety contactors.
How are parameters transferred to a replacement EVS9330-ESV004 drive?
Parameters can be transferred by cloning parameter sets stored in the internal EEPROM using the optional XT Keypad (EMF2102IB) directly at the drive, or by uploading and downloading configuration files via Lenze Global Drive Control (GDC) software over the system bus adapter.
Which fieldbus communication options are supported by this servo drive?
In addition to its built-in CAN System Bus (CANopen), the EVS9330-ESV004 supports fieldbus expansion modules via Automation Slot A. Compatible modules include PROFIBUS-DP (EMF2133IB/EMF2131IB), DeviceNet (EMF2177IB/EMF2174IB), and INTERBUS (EMF2113IB/EMF2111IB).
What does a solid red TRIP LED indicate on the front panel?
A solid red TRIP LED indicates an active inverter fault condition. When active, the inverter output stage is disabled. The fault cause can be identified using the XT Keypad, GDC software, or reading diagnostic registers over the system bus.
What action should be taken if the drive displays an H05 fault code?
An H05 fault code indicates an internal hardware failure on the control board or internal circuitry. First perform a complete power cycle; if the fault persists upon rebooting, the drive requires hardware repair or replacement.
