Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9331-EP (type number 13180724) is a heavy-duty servo position controller from the Lenze 9300 series designed for high-performance motion applications. Powered by a 3-phase AC input supply ranging from 320 to 528 V AC or an alternative DC bus supply of 460 to 740 V DC, this 55 kW (75 HP) drive delivers a continuous output current of 110 A at an 8 kHz switching frequency or 70 A at 16 kHz, with a total apparent power output of 76.2 kVA. Housed in a robust IP20 and NEMA 1 rated enclosure measuring 750 mm high by 450 mm wide by 285 mm deep and weighing 59 kg, the drive provides reliable decentralized servo control in packaging, material handling, automotive, printing, and converting systems.
Integrated motion control is a core feature of the -EP variant, allowing positioning sequences, motion profiles, and target mark evaluations to be calculated directly on the drive rather than relying on an external positioning controller. Physical I/O connections include five digital inputs, four digital outputs, two analog inputs (-10V to +10V or -20mA to +20mA), and two analog outputs (-10V to +10V), alongside dedicated thermistor inputs for PTC or KTY motor temperature monitoring. System integration and network connectivity are achieved through plug-in fieldbus communication modules, including PROFIBUS-DP (EMF2133IB), DeviceNet or CANopen (EMF2175IB), INTERBUS (EMF2113IB), and LECOM RS-422/485 options (EMF2102IBV001 / EMF2102IBV002). Commissioning a replacement unit requires matching drive configurations, transferring stored parameter sets via the optional Keypad XT (EMZ9371BC) interface, and re-installing any installed communication card.
System diagnostics and operating status are managed primarily through the plug-in Keypad XT (EMZ9371BC), which provides live monitoring of drive parameters, operation status, and historical fault readouts. Diagnostic capabilities extend across connected network interfaces via optional LECOM or fieldbus option modules. When commissioning or troubleshooting an installed drive, technicians should verify line input voltage, motor encoder feedback, control wiring, thermistor circuits, and proper fieldbus module seatings. Severe power stage or internal electronic failures require specialized testing and component-level service; ABC Industrial Parts provides tested replacement units and repair options to minimize machine downtime.

Programming and Configuration
The Lenze EVS9331-EP positioning servo controller executes complex motion routines internally, eliminating the requirement for external positioning modules. Operating parameters and motion profiles are configured directly within the drive logic, enabling execution of positioning sequences, limit switch processing, and automatic setpoint position drift compensation via target mark signal evaluation.
Parameter transfer and local drive configuration are facilitated using the plug-in Keypad XT (EMZ9371BC). Machine-specific parameter sets, speed profiles, and acceleration ramps can be stored and uploaded to replacement drives during maintenance procedures, ensuring consistent motion profile replication across hardware swaps.
Communication and System Integration
Modular architecture allows the EVS9331-EP to interface with broader plant control networks through optional communication modules. The drive slot accepts standard plug-in cards for fieldbus architectures, enabling setpoint distribution, status feedback, and remote control from central industrial PLCs.
Supported communication modules include PROFIBUS-DP (EMF2133IB), DeviceNet / CANopen (EMF2175IB), INTERBUS (EMF2113IB), and LECOM RS-422/485 serial interfaces (EMF2102IBV001 / EMF2102IBV002). These modules enable integration into existing fieldbus installations without changing the core drive hardware.
Diagnostics and Status Indication
Local diagnostic capabilities for the Lenze EVS9331-EP center around the plug-in Keypad XT (EMZ9371BC) interface module. The keypad provides access to real-time operating metrics, current feedback, drive operating states, and a dedicated fault memory log for inspecting past trip events.
Network-level status monitoring and diagnostic telegrams can also be processed via installed LECOM or fieldbus communication modules, allowing supervisory controllers to inspect drive readiness and system fault states remotely over the bus network.
Replacement and Spare Part Considerations
When replacing an existing Lenze EVS9331-EP (13180724) servo controller, the replacement unit must match the physical footprint and power ratings of the original drive. The unit features dimensions of 750 mm in height, 450 mm in width, and 285 mm in depth, with a total weight of 59 kg, requiring appropriate panel mounting and cooling clearances in IP20 / NEMA 1 enclosures.
Prior to putting a spare drive into service, maintenance personnel must transfer all parameter settings from the original controller using a Keypad XT (EMZ9371BC) or configuration software. The fieldbus communication module (such as PROFIBUS-DP EMF2133IB or DeviceNet/CANopen EMF2175IB) must be swapped onto the replacement drive, and external wiring—including the 5 digital inputs, 4 digital outputs, analog I/O, and PTC/KTY motor thermistor sensor connections—must be restored to match original panel schematics.
