Product Information
The Lenze 13431044 EVS9327-ES is an 11 kW servo inverter within the Lenze 9300 Servo series, engineered for dynamic speed and torque regulation of synchronous and asynchronous motors. As a dedicated -ES design variant, this drive operates on a 3-phase mains supply from 320 V AC to 528 V AC with a nominal rating of 400/480 V AC. It delivers a continuous rated output current of 23.5 A and a maximum peak current of 35.3 A, supporting heavy overload demands up to 150% continuous output current for 60 seconds during acceleration cycles. Built around field-oriented vector control and an 8 kHz switching frequency, the drive provides dynamic motion performance across packaging, textile, printing, converting, and automotive production environments.
For integration and control, the EVS9327-ES includes an onboard CAN system bus interface alongside a modular Automation Interface (AIF) slot that accepts fieldbus cards such as the EMF2133IB PROFIBUS DP and EMF2173IB DeviceNet communication modules. Physical interfaces include five digital inputs, four digital outputs, two analog inputs, two analog outputs, a resolver feedback input on connector X7, an encoder input on connector X8, and an encoder simulation output for master-slave synchronization. Commissioning a spare drive requires transferring operational parameters, as the unit relies on non-volatile EEPROM memory holding up to four distinct parameter sets. Parameter transfer can be completed using the pluggable EMF2102IB XT keypad module or Lenze Global Drive Control (GDC) software to restore original drive parameters with support from ABC Industrial Parts.
Drive status and operating conditions are indicated via three multi-color LED indicators representing operational status, warning levels, and active fault states. System diagnostics can be conducted through the TRIP memory buffer in parameter C0161 or C0168, accessible via the EMF2102IB keypad display or the GDC software oscilloscope function. First-line troubleshooting involves checking input mains power supply across 320 V AC to 528 V AC, verifying power wiring for phase-to-phase or phase-to-earth shorts, inspecting resolver cabling on connector X7, and testing 120-ohm CAN bus line terminations. If internal microcontroller or control board failures such as fault code H05 occur, hardware cannot be repaired in the field, making a tested replacement unit or repair service through ABC Industrial Parts the recommended solution.

Programming and Configuration
The Lenze 13431044 EVS9327-ES servo inverter is configured using Lenze Global Drive Control (GDC) PC software or the optional pluggable EMF2102IB XT Keypad Operating Module. Parameter storage is handled inside non-volatile EEPROM memory capable of holding up to four complete parameter sets, allowing multi-product setups or operational profile switching without re-downloading complete drive configurations.
When transferring or adjusting parameters, the pluggable keypad module enables direct parameter backup and parameter set cloning across drives. Parameter history log inspection is accessible via codes C0161 and C0168. If a parameter set becomes corrupted during operational transfer, fault code PR signals the memory issue, which can be cleared by loading factory default settings through code C0002 before re-applying custom parameters.
Communication and System Integration
System communication on the EVS9327-ES relies on an integrated CAN system bus alongside a flexible Automation Interface (AIF) expansion slot. The onboard CAN bus allows direct multi-drive network integration and centralized control commands. Correct CAN operation requires 120-ohm termination resistors fitted at both ends of the CAN bus line to avoid telegram interruptions such as CE1 or CE2 communication faults.
The modular AIF slot connects the drive to higher-level automation fieldbuses via add-on modules, including the EMF2133IB PROFIBUS DP card and the EMF2173IB DeviceNet card, as well as INTERBUS and LECOM serial communication adapters. Discrete I/O handling is supported through five digital inputs, four digital outputs, two analog inputs, and two analog outputs, complemented by resolver input X7, encoder input X8, and an encoder simulation output.
Diagnostics and Status Indication
Operational state monitoring for the EVS9327-ES drive is displayed via three front panel status LEDs. Detailed diagnostic evaluation is performed by reading fault memory codes C0161 and C0168 through the EMF2102IB keypad module display or using the diagnostic monitor and live oscilloscope tool within Lenze Global Drive Control software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid | Fault state (TRIP active). Drive is inhibited due to active fault condition. |
| Green LED | Green - Solid or Flashing | Operational state (Drive Ready / Running). Blinking indicates controller inhibit or phase operation. |
| Yellow LED | Yellow - Solid | Warning condition active or current limit reached. |
Replacement and Spare Part Considerations
When installing a replacement Lenze 13431044 EVS9327-ES module, confirm that the power specification of 11 kW and nominal supply rating of 400/480 V AC match the target machine's original configuration. Any optional communication card installed in the AIF slot, such as the EMF2133IB PROFIBUS DP or EMF2173IB DeviceNet module, must be transferred to the replacement drive to preserve network integration.
A replacement unit requires parameter loading before it can operate. The parameter set should be transferred from the original unit or downloaded from a saved configuration file using Lenze Global Drive Control (GDC) software or the EMF2102IB keypad module. For long-term system modernization, Lenze designates the i950 Servo Inverter as the recommended successor series.
