Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00470841 EVS9330-ES is a 45 kW servo inverter drive from the Lenze 9300 Servo family, engineered for high-precision vector-oriented motor control in complex multi-axis industrial automation systems. Designed for demanding applications such as packaging machinery, textile manufacturing, automotive assembly, and converting lines, this drive operates across a 3-phase supply voltage range of 320 V AC to 528 V AC. It provides an 89 A continuous output current and features a 150% peak overload capacity (up to 133.5 A) to handle heavy dynamic acceleration and precise torque or speed control requirements.
Interfacing the EVS9330-ES into an existing control cabinet relies on flexible feedback and network connections, including a dedicated 9-pin D-sub resolver input at interface X7 and encoder input/output channels at X8 and X9 supporting signal frequencies up to 500 kHz. For system-level integration, the integrated CAN-based Lenze System Bus at interface X4 enables direct cross-axis synchronization at rates up to 500 kbit/s, while Option Slot A accepts optional fieldbus modules such as the EMF2131IB or EMF2133IB for PROFIBUS-DP and EMF2172IB for CANopen. Commissioning a replacement unit requires restoring parameter settings, which can be transferred using Lenze Global Drive Control (GDC) software, Easy Starter, or an EMZ9371BC keypad by drawing from the drive onboard EEPROM memory that holds up to four independent parameter sets. When installing a replacement drive, ABC Industrial Parts can assist in ensuring configuration parameter files and option modules are properly transferred before putting the machine back into service.
Operational monitoring and fault diagnostics are provided via front-panel dual LEDs, the optional EMZ9371BC pluggable keypad, and GDC diagnostic software, alongside an integrated fault history register (Code C0168) that retains up to 8 recorded fault events. A solid green LED indicates normal enabled operation, while a blinking green LED signals a controller inhibit (CINH) state; a solid red LED denotes an active TRIP fault state that disables the output stage, and a blinking red LED signals an active warning. System fault codes address conditions such as overcurrent (OC1), earth faults (OC2), DC bus overvoltage or undervoltage (OU, LU), heatsink or ambient overtemperature (OH, OH4), feedback signal interruptions (P12, P13), and communication errors on Slot A (CE0) or System Bus (CE1). For internal hardware faults such as code H05 or EEPROM corruption (EER) that cannot be cleared through a power cycle or parameter reload, internal board failures are not field-serviceable, making repair services or a fully tested exchange unit from ABC Industrial Parts the most reliable path to restore production.

Programming and Configuration
Parameterization and commissioning of the Lenze EVS9330-ES servo drive are performed using Lenze Global Drive Control (GDC) software, Easy Starter, or the pluggable EMZ9371BC diagnostic keypad. The drive contains non-volatile EEPROM memory capable of storing up to four complete, independent parameter sets. This onboard memory architecture enables convenient cloning and rapid backup of drive settings across identical axes or replacement units.
Commissioning a spare drive requires matching drive parameters to the specific motor characteristics, position feedback devices, and application safety thresholds. Settings can be uploaded from an existing drive or written directly to the target drive using GDC software or by transferring saved parameter files via the EMZ9371BC keypad. Selecting factory default restoration (Code C0002=1) allows technicians to clear legacy parameters prior to reloading clean application configurations.
Communication and System Integration
High-speed multi-axis communication on the EVS9330-ES is handled directly via the integrated Lenze System Bus at connection X4. Utilizing CAN technology running at transmission speeds up to 500 kbit/s, this bus allows rapid cross-axis data exchange, synchronized speed hold, and positioning commands between multiple drives without requiring external motion control hardware.
For integration with higher-level plant automation networks, the drive features a dedicated expansion interface designated as Option Slot A. Modular fieldbus adapters, including the EMF2131IB / 2133IB PROFIBUS-DP module and the EMF2172IB CANopen module, install directly into Option Slot A. Proper bus installation requires verified cable shielding, matching network baud rates, and correct 120-ohm termination resistors at both ends of the CAN system bus line.
Diagnostics and Status Indication
The EVS9330-ES provides real-time status feedback through front-mounted dual LED indicators, the pluggable EMZ9371BC keypad display, and live monitoring within Lenze Global Drive Control (GDC) software. Fault history analysis is supported by internal register Code C0168, which logs up to 8 historical fault events for diagnostic review and root-cause troubleshooting.
The primary status indicators consist of a green Operation/Ready LED and a red TRIP/Fault LED. The green LED glows solid when the drive controller is enabled and operational, and blinks when controller inhibit (CINH) is active. The red LED illuminates solid when a TRIP fault condition disables the output stage, and blinks when an active system warning is detected.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation / Ready) | Green - Solid / Blinking | Solid: Controller enabled, normal operating state. Blinking: Controller inhibit active (CINH). |
| Red LED (TRIP / Fault) | Red - Solid / Blinking | Solid: Active fault (TRIP state, output stage disabled). Blinking: Warning active. |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVS9330-ES (00470841) servo drive, verify that the physical unit matches the required 45 kW power rating and 89 A continuous output specification. Ensure any installed fieldbus option module in Option Slot A, such as PROFIBUS-DP or CANopen cards, is transferred to the replacement drive to preserve network connectivity.
Before enabling the replacement drive, parameter memory must be synchronized. Parameter sets stored in the EEPROM of the original drive can be extracted using GDC software or transferred via the EMZ9371BC keypad. Following parameter download, verify motor feedback signal integrity at sockets X7, X8, or X9, confirm bus termination resistance on interface X4, and check thermal sensor connections at terminals T1 and T2 prior to applying mains power.

Frequently Asked Questions
How are parameters copied from an existing EVS9330-ES to a replacement drive?
Parameters can be cloned using an EMZ9371BC diagnostic keypad or Lenze Global Drive Control (GDC) software by uploading the configuration from the original drive's onboard EEPROM and downloading it into the new unit.

The drive operates on a 3-phase AC input voltage range of 320 V AC to 528 V AC.
How does the EVS9330-ES communicate across multiple drive axes?
The drive features an integrated CAN-based Lenze System Bus at interface X4, operating at up to 500 kbit/s for multi-axis drive synchronization without an external motion controller.
What do the green and red status LEDs on the front panel indicate?
A solid green LED indicates normal enabled operation, while a blinking green LED indicates controller inhibit (CINH). A solid red LED indicates a TRIP fault state with output disabled, while a blinking red LED indicates an active warning.
