Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9324-ES is an 11 kW AC servo inverter drive from the Lenze 9300 Servo series, engineered for high-precision, dynamic motion control in automated industrial machinery. Operating on a three-phase line supply from 320 V AC to 528 V AC with a rated input current of 27 A, the drive delivers a continuous output current of 23.5 A and a maximum output frequency of 480 Hz. Variable switching frequencies up to 16 kHz allow for quiet motor operation and precise torque control. Built-in feedback evaluation accommodates standard resolvers and RS422 incremental encoders with simulated frequency output. Typical applications include high-dynamic multi-axis positioning systems, continuous material web tension control, precision gantry pick-and-place robots, packaging machinery, textile equipment, automotive assembly lines, and printing presses.
Network integration and real-time motion control are handled through the integrated CANopen system bus interface located on terminal strip X14, supporting transmission rates up to 500 kbit/s. For machinery operating on alternative fieldbus protocols, the front panel features an Automation Interface (AIF) slot that accepts plug-in communication modules including PROFIBUS-DP (EMF2133IB), DeviceNet (EMF2173IB), and INTERBUS (EMF2105IB). Commissioning a replacement unit requires loading the application parameter configuration to match the drive to the target motor and machine sequence. The drive contains non-volatile EEPROM memory capable of storing up to four complete parameter sets. Parameters can be created and managed using Lenze Global Drive Control (GDC) software or transferred directly from another unit using the pluggable EMZ9371BC operating keypad. When commissioning replacement hardware or recovering parameter sets from an inactive board, technical support from ABC Industrial Parts helps ensure accurate parameter alignment before restart.
Operational status and unit readiness are signaled via front panel LEDs, including a green Ready LED and a red Fault LED. Detailed diagnostic data and trip history are recorded in memory parameters C0161 through C0170, forming a log accessible through the EMZ9371BC keypad text display or the GDC diagnostic workspace. Common system trips include heatsink overtemperature (OH), DC bus overvoltage (OU), DC bus undervoltage (LU), input phase loss (P12), or resolver tracking errors on terminal X7 (rPO, Sd3). Initial troubleshooting steps involve checking mains supply voltage across input terminals, inspecting cabinet ventilation and cooling fans, and verifying resolver wiring continuity and shielding. Internal hardware failures (H05), EEPROM checksum corruption (EER), or power section transistor faults (OC1) indicate internal component defects that cannot be serviced in the field. Under these conditions, replacing the drive with a tested unit or arranging a repair through ABC Industrial Parts provides the fastest route to restored operations.

Programming and Configuration
Programming and parameter management for the Lenze EVS9324-ES drive are conducted using Global Drive Control (GDC) engineering software. This software tool allows technicians to configure motor control dynamics, setup position loops, fine-tune gain settings, and back up complete drive configurations to PC storage.
For localized setup and parameter editing without a computer, the optional EMZ9371BC operating keypad snaps into the front Automation Interface (AIF) slot. Up to four complete parameter sets can be written to and retained within non-volatile onboard EEPROM, making it easy to store secondary operating profiles or clone drive parameters during replacement procedures.
Communication and System Integration
The EVS9324-ES includes a built-in CANopen system bus interface accessible on terminal strip X14. Operating at transmission speeds up to 500 kbit/s, this integrated port allows synchronized multi-axis control, rapid setpoint communication, and inter-drive parameter transfer across automation networks.
To integrate into external control environments, the drive provides an Automation Interface (AIF) slot on the front fascia. This slot accepts fieldbus option cards including the EMF2133IB PROFIBUS-DP module, EMF2173IB DeviceNet module, and EMF2105IB INTERBUS module, enabling seamless connection to higher-level PLC architectures.
Diagnostics and Status Indication
The drive provides immediate visual status monitoring via two front panel LED indicators. The green Ready LED communicates power supply and operational status, while the red Fault LED signals trip conditions, interlocks, or active error states.
Detailed historical diagnostics are logged in internal memory parameters C0161 through C0170, which store a TRIP history buffer. Maintenance personnel can interrogate this buffer using the text display on the EMZ9371BC operating keypad or through the dedicated diagnostic window inside Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready LED | Green - Solid / Flashing | Drive controller operational readiness and supply status |
| Fault LED | Red - Solid / Flashing | Active drive trip or warning error condition detected |
Replacement and Spare Part Considerations
When installing a replacement Lenze EVS9324-ES, confirm that the model type and hardware revisions align with the original unit. Because modern drives require specific parameterization to operate attached motors correctly, a spare unit must be configured with a restored parameter backup prior to operating the machinery.
Parameter transfer can be accomplished by copying saved profiles from an EMZ9371BC keypad into the replacement drive or by writing a saved backup project file via Global Drive Control (GDC) software. If the original installation utilizes an option card in the AIF slot (such as the EMF2133IB PROFIBUS module), transfer the module to the new drive and ensure all fieldbus address selectors match the original settings.

Frequently Asked Questions
How do I transfer parameters to a replacement Lenze EVS9324-ES drive?
Parameters can be saved from the original drive onto an EMZ9371BC operating keypad and transferred directly to the replacement unit. Alternatively, parameter backup files can be downloaded using Lenze Global Drive Control (GDC) software.
What motor feedback options are supported by the EVS9324-ES?
The EVS9324-ES includes built-in evaluation hardware for standard resolvers along with input terminals for RS422 incremental encoders and simulated frequency outputs.
Which fieldbus interfaces are available for this drive?
The drive includes an onboard CANopen system bus interface on terminal strip X14. Additional fieldbus protocols including PROFIBUS-DP (EMF2133IB), DeviceNet (EMF2173IB), and INTERBUS (EMF2105IB) are supported by adding the corresponding module to the front Automation Interface (AIF) slot.
What do the front panel status LEDs indicate?
The green Ready LED indicates operational readiness and control power supply status. The red Fault LED lights or flashes when an active trip condition, interlock, or fault alert occurs.
How can I check trip history on the EVS9324-ES?
The drive maintains a TRIP history log in diagnostic parameters C0161 to C0170. This buffer can be read directly on the EMZ9371BC keypad display or viewed within the GDC software diagnostic workspace.
What steps should be taken if fault code OC1 or H05 is displayed?
Fault code OC1 indicates an overcurrent or short circuit, while H05 indicates an internal hardware failure. For OC1, disconnect the motor wires at terminals U/V/W to test if the drive trips independently; if OC1 persists with wires removed or if H05 is present, internal board component failure has occurred and the unit requires professional repair or replacement.
