Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13294358 EVS9329-EP is a 30 kW industrial servo drive engineered for high-precision motion control within the Lenze 9300 Positioning Controller series. Designed to operate on a 3-phase AC supply ranging from 320 V to 528 V, this drive delivers a continuous output current of 89 A at an 8 kHz switching frequency, with a peak output capacity of 133.5 A to handle high-torque acceleration ramps. The -EP variant integrates dedicated positioning control function blocks, speed regulation, and vector control directly into the drive hardware, eliminating the need for separate external positioning cards in multi-axis assembly, rotary indexing, and material transfer applications.
Interfacing with master control systems is handled via an onboard CAN/CANopen system bus running at up to 500 kbit/s, alongside dedicated resolver and incremental encoder inputs, 6 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. The drive features an Automation Interface (AIF) slot for plug-in fieldbus modules, such as the EMF2133IB PROFIBUS-DP or EMF2175IB DeviceNet cards. Commissioning a replacement spare requires transferring the configuration parameters to match the active machine setup. Drive parameters can be migrated across four internal EEPROM parameter sets using the 9371BB keypad operating module or Lenze Global Drive Control (GDC) software. Technical specialists at ABC Industrial Parts can assist with parameter extraction and configuration matching when restoring a replacement drive to service.
Diagnostic conditions are reported visually on the front panel status LEDs and remotely via terminal X5/A1 TRIP output signaling or GDC software dashboards. A solid green LED indicates the drive is ready for operation, while a blinking green LED signals enabled active status; a solid red LED indicates a TRIP fault with the output stage disabled. Fault history records are logged under parameters C0168 and C0169, covering events such as overcurrent (OC1), earth faults (OC2), heatsink overtemperature (OH), or communication loss (CE0/CE1). If memory corruption errors (EER) persist after resetting to factory defaults or if an internal hardware fault (H05) occurs, internal electronics have failed, and obtaining a pre-tested exchange unit through ABC Industrial Parts provides a direct route back to production.

Programming and Configuration
Programming and parameter administration for the Lenze 13294358 EVS9329-EP are managed through Lenze Global Drive Control (GDC) software or directly on the drive using the optional 9371BB keypad operating module. The drive contains four non-volatile internal parameter sets within EEPROM memory, enabling switching between distinct operational profiles or motion configurations without reloading data from an external controller.
When commissioning a spare unit, parameter cloning can be performed directly via the 9371BB keypad by copying parameter sets from a functional donor unit. Alternatively, GDC software connects to the drive interface to upload project backups, modify feedback settings, adjust speed controller gain parameters, or restore default configurations by setting parameter C0002 to value 1.
Communication and System Integration
The EVS9329-EP features an onboard CAN/CANopen system bus operating at communication rates up to 500 kbit/s, enabling multi-axis drive synchronization and rapid data exchange with CAN network masters. Dedicated feedback interfaces accommodate resolvers via SUB-D connector X7 as well as incremental encoders.
Network integration with primary fieldbus systems is supported through an Automation Interface (AIF) slot. This interface accepts option cards including the EMF2133IB PROFIBUS-DP and EMF2175IB DeviceNet modules, alongside INTERBUS and serial LECOM options. Additional system control is provided via 6 digital inputs, 4 digital outputs, 2 analog inputs, 2 analog outputs, and dedicated Safe Torque Off (STO) terminals built to EN ISO 13849-1 standards.
Diagnostics and Status Indication
Real-time operational status is displayed on the front panel via dual LEDs. The green Ready/Operation LED shows a solid light during completed initialization and blinks when the output stage is enabled and running. The red TRIP/Fault LED illuminates solid when a TRIP fault disables the power stage and blinks during active warnings or IMP messages.
Comprehensive diagnostic testing is accessible through the 9371BB keypad display or the GDC software diagnostic dashboard. Current fault status and past operational events are stored in parameter registers C0168 and C0169. Remote diagnostic signaling to external control hardware is available using digital output terminal X5/A1.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Operation (Green LED) | Green - Solid / Blinking | Green Solid: Drive initialized and ready for operation; Green Blinking: Drive enabled and operating. |
| TRIP / Fault (Red LED) | Red - Solid / Blinking | Red Solid: Drive in TRIP fault status with output stage disabled; Red Blinking: Warning or IMP message active. |
Replacement and Spare Part Considerations
When sourcing a replacement unit, verifying the exact model suffix EVS9329-EP and part number 13294358 is critical. The -EP variant incorporates internal positioning block functionality that standard speed control drives lack, ensuring that multi-axis motion and indexing control function properly.
Before installing a spare drive, parameter sets must be transferred from the original unit using either the 9371BB keypad module or Global Drive Control (GDC) software. Any optional fieldbus cards installed in the AIF slot, such as an EMF2133IB PROFIBUS-DP or EMF2175IB DeviceNet module, must be moved to the replacement drive and checked for correct node address and baud rate settings. Terminal wiring for Safe Torque Off (STO) inputs and motor thermal protection on terminals T1/T2 should be verified prior to applying power.

Frequently Asked Questions
What software is used to configure the Lenze EVS9329-EP drive?
Lenze Global Drive Control (GDC) engineering software is used to configure parameters, transfer motion profiles, and perform live diagnostics. Parameters can also be modified using the optional 9371BB keypad operating module.
Can an EVS9329-EP drive be replaced by a standard 9300 series drive?
No. The -EP suffix designates integrated positioning control function blocks required for positioning tasks. Standard 9300 drive variants lack these software blocks and will not support positioning operations.
How are drive parameters transferred to a replacement unit?
Parameters stored across the four internal EEPROM parameter sets can be cloned directly using the 9371BB keypad module or uploaded and downloaded using GDC software.
What do the green and red status LEDs indicate on the EVS9329-EP?
A solid green LED indicates the drive is initialized and ready, while a blinking green LED means the drive is enabled and operating. A solid red LED indicates a active TRIP fault with the output stage disabled, and a blinking red LED signals an active warning.
What should be done if an EER or H05 error code is displayed?
An EER error indicates an EEPROM memory issue and can be tested by resetting parameters to factory defaults via parameter C0002 = 1. An H05 fault indicates an internal hardware failure. If these errors persist after power cycling, internal board components have failed and the drive requires repair or replacement.
