EVS9327-EI - Position controller - LENZE

Lenze EVS9327-EI, 9300 series brushless controller for demanding industrial axes

Designed for engineering offices, integrators and maintenance teams, the Lenze EVS9327-EI controller from the 9300 series meets the needs of axis control where stability, repeatability and configurable flexibility are essential. This model drives synchronous and asynchronous motors, with encoder feedback depending on the variant, and covers the three key industrial motion control functions: speed, position and torque regulation. It integrates into automation architectures via the interfaces provided on the 9300 series, simplifying use in new installations or retrofits. Configuration is accessible and structured via the external command keypad XT EMZ9371 BC and Lenze software, allowing management of parameter sets, acceleration and deceleration ramps, as well as brake functions. Designed for cabinet mounting and three-phase 400 V supply, the EVS9327 family offers power ratings suited to many machines, up to approximately 15 kW depending on configuration. The EI variant belongs to this family and inherits the series' common features; its I/O and interface options should be confirmed according to your requirements.

Control performance and operational efficiency

• Trajectory control – Position and speed regulation enable precise, repeatable movements, essential for assembly, packaging and conveying.
• Stabilised productivity – Torque management and ramp control limit mechanical jerks, reduce wear and improve equipment availability.
• Secure configuration – Parameter sets and the Lenze configuration tool simplify commissioning, axis duplication and fine tuning without drift.
• Simplified integration – The 9300 series interfaces and buses ensure coherent communication with existing PLCs, depending on the installed version.
• Installation longevity – Compatibility with synchronous and asynchronous motors, with encoder feedback depending on variant, extends machine life in contexts of obsolescence.

Technical architecture and design quality

The Lenze EVS9327-EI is based on the proven architecture of the 9300 series. The device is intended for cabinet mounting on a three-phase 400 V network, matching European production line standards. Basic functions include speed, position and torque regulation, with possibilities for optimisation via acceleration and deceleration profiles and brake control. Configuration via the XT EMZ9371 BC keypad, combined with Lenze software, provides structured navigation, saving and recalling parameter sets, and contributes to commissioning repeatability. Compatibility with synchronous and asynchronous motors, with encoder feedback depending on the variant, allows the control loop to be adapted to the intended application, whether constant speed maintenance, indexed positioning or torque control. The entire EVS9327 family covers power ranges enabling supply of axes up to approximately 15 kW depending on configuration. For the EI sub-reference, interface, I/O and firmware options must be checked, the device remaining technically aligned with the capabilities of the 9300 series.

Typical applications and use cases

The EVS9327-EI brushless controller is suitable for packaging, handling and conveying axes, dosing modules, rewinders and unwinder units, as well as textile and assembly machines. Integrators use it for motion profiles combining precision and throughput, while maintenance teams appreciate consistent configuration for quick return to service after interventions. In retrofit projects, support for synchronous or asynchronous motors allows leveraging existing equipment.

Differentiation, reliability and support

The 9300 series from LENZE is recognised for its robustness, clear configuration logic and industrial compatibility. The EVS9327-EI variant continues this legacy with comprehensive regulation functions and controlled integration into automation.
