Product Information
The Lenze 13015894 (model EVS9324-ES) is a 5.5 kW panel-mounted AC servo inverter drive belonging to the Lenze 9300 Servo series. Designed for high-dynamic motion control applications, this unit operates on a three-phase supply voltage ranging from 320 to 528 V AC (nominal 400/480 V AC) with a rated input current of 12 A. The drive delivers a continuous output current of 13 A at an 8 kHz switching frequency, with a peak output current capability of 19.5 A for up to 60 seconds. Utilizing Field Oriented Control (FOC) algorithms across an output frequency range of 0 to 480 Hz, it provides precise positioning, speed, and torque control for synchronous and asynchronous AC servo motors in automated packaging, printing, material handling, and plastics machinery.
Physical integration features an onboard Sub-D connector for primary resolver feedback, incremental encoder feedback ports, an integrated Lenze CAN system bus interface, and a modular Automation Interface (AIF) slot for plug-in fieldbus modules such as the PROFIBUS-DP EMF2133IB or CANopen EMF2178IB. Commissioning or installing a replacement unit requires restoring the drive parameters to match the target machine's operating profile. The drive stores up to four complete parameter sets in internal non-volatile memory, which can be extracted and loaded using the plug-in Keypad XT (EMF2102IB) or Lenze Global Drive Control (GDC) software via a USB-to-CAN adapter (EMF2177IB). To ensure seamless line startup, ABC Industrial Parts can assist with extracting parameter profiles from existing drives or donor hardware.
System status and diagnostics are communicated via three front panel status LEDs—Red, Green, and Yellow—which indicate controller states, active trip conditions, warning limits, and specific fault group blinking codes. Detailed diagnostic monitoring and a fault history memory buffer can be accessed directly using Keypad XT or GDC software to inspect real-time metrics such as DC bus voltage, output current, motor speed, and heatsink temperature. While field-level faults like overvoltage (OU), undervoltage (LU), or overcurrent (OC1) can often be resolved by checking supply lines, braking resistors, or motor insulation, internal hardware errors such as EEPROM failure (EER), control board faults (H05), or power section errors (H10) are non-field-serviceable. In these instances, obtaining a fully tested replacement drive or unit repair through ABC Industrial Parts provides the fastest path to restoring operational productivity.

Programming and Configuration
Parameter management and programming for the Lenze EVS9324-ES are conducted using Lenze Global Drive Control (GDC) software or the optional Keypad XT (EMF2102IB). Software connectivity is established through the Lenze CAN system bus using a USB-to-CAN Adapter (EMF2177IB). GDC allows technicians to configure motion profiles, adjust Field Oriented Control loop parameters, set dynamic limits, and monitor live drive telemetry.
The EVS9324-ES features internal non-volatile EEPROM memory capable of retaining up to four complete parameter sets without requiring battery backup. When replacing an operational unit, parameters must be cloned from the active drive to the replacement module to preserve motor settings, feedback calibration, network node identifiers, and I/O assignments. If parameter data becomes corrupted, fault code PR0 triggers, requiring a backup restore from GDC or reload of factory defaults.
Communication and System Integration
Network communication is natively supported via the built-in Lenze CAN system bus, which operates at transmission speeds up to 500 kbps over terminal block X4. The CAN interface facilitates high-speed peer-to-peer data exchange, axis synchronization, and master-slave velocity or torque commands across multi-axis production systems. Proper bus termination with 120-ohm resistors at physical line ends is required to prevent communication interruptions.
System integration flexibility is expanded through the onboard Automation Interface (AIF) slot, which accommodates plug-in communication modules. Supported option cards include the PROFIBUS-DP module EMF2133IB and CANopen module EMF2178IB, as well as INTERBUS options. The AIF module allows the servo drive to interface directly with higher-level PLCs and plant automation networks. Communication timeouts between the main control card and the AIF module trip fault code CE1, requiring verification of card seating and network cabling.
Diagnostics and Status Indication
Real-time status indication on the EVS9324-ES is provided by three diagnostic LEDs located on the front panel. The Green LED indicates operational readiness or controller enable state, flashing when inhibited and solid when running. The Yellow LED illuminates or flashes during warning conditions, such as current limit threshold activation. The Red LED flashes error group codes during trip events or remains continuously lit during severe drive faults.
Detailed diagnostic evaluation is performed via Keypad XT or GDC software, which provides access to an internal fault history memory buffer. Maintenance personnel can monitor real-time operating variables including DC bus voltage, output current, motor speed, and heatsink temperature.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid / Blinking | Drive fault or TRIP active; blinking code indicates error group, steady illumination indicates critical fault. |
| Green LED | Green - Solid / Blinking | Blinking indicates controller ready or inhibited; continuous indicates controller enabled and operating. |
| Yellow LED | Yellow - Solid / Blinking | Warning indicator or special controller state such as current limit reached. |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVS9324-ES servo drive, match the complete part number (13015894) and model designation to ensure identical electrical ratings and control card compatibility. Verify that the incoming supply voltage matches the 320 to 528 V AC operating window and that the existing braking resistor and motor feedback connections match the Sub-D resolver input (X7) or encoder ports.
Replacement units are not plug-and-play and must be configured with the specific parameter set from the original drive before operation. Transfer parameter profiles using Keypad XT (EMF2102IB) or GDC software over a USB-to-CAN connection. Ensure that any installed AIF fieldbus option cards—such as PROFIBUS-DP (EMF2133IB) or CANopen (EMF2178IB)—are transferred to the spare unit and properly seated in the AIF slot, with network node addresses and termination resistors reconfigured as required.
