EVS9321-EP - Position controller - LENZE

Lenze EVS9321-EP Brushless Controller - 9300 Series

The Lenze EVS9321-EP is a brushless controller from the 9300 series intended for axis positioning and motion control of synchronous motors. Designed for system integrators, maintenance services and machine builders, it meets requirements for accuracy, stability and production availability. Its architecture is suited to compact drive applications, with a 3 x 400 to 480 V AC, 50/60 Hz supply, a rated power of approx. 0.37 kW and a 1.5 A output current. The 9300 series provides a modular platform focused on speed, torque and position control, making it a relevant choice for servodriven axes operating in continuous indexing or intermittent positioning in conveyor, assembly and packaging environments. The EVS9321-EP stands out for straightforward implementation and easy integration into existing automation architectures, whether involving programmable logic controllers, numerical controllers or distributed motion control systems.

Overview of the Lenze 9300 series

The 9300 series from Lenze groups drives and controllers dedicated to industrial motion control. Its philosophy is based on a modular platform allowing precise tailoring of closed-loop functions to the intended application, whether stabilising speed, controlling applied torque or positioning synchronous axes. The consistency across the range facilitates standardisation of components at production-line level, simplifying maintenance and spare parts availability. For machines already in service, the functional continuity of the 9300 series enables quick replacements and retrofits that minimise downtime.

• Modules oriented to positioning : dedicated to indexing sequences, homing operations and repeated motion profiles with tight accuracy requirements.
• Speed and torque regulation modules : suited to drives requiring stable speed holding and controlled torque during transients.

In this context, the EVS9321-EP targets compact axes where tracking quality and motion repeatability determine machine performance and product conformity.

Industrial applications

Due to its sizing and control functions, this brushless controller integrates into environments where an axis must execute precise and repeatable motion profiles. The following sectors commonly use this type of servo-drive in their production equipment.

• Conveying and sorting : stop positioning, synchronization of accumulation axes, indexing of transfer units.
• Handling and pick-and-place : control of compact axes with short cycles and frequent restarts.
• Packaging and filling : control of labelling heads, cutting units and repetitive motion waveforms.
• Assembly and special-purpose machines : indexing rates, homing, tool positioning.
• Traceability and marking : synchronisation of product feed with print registration.

Integration and communication

The EVS9321-EP fits into existing automation architectures via the interfaces provided by the 9300 series and, depending on configuration, by adding optional communication cards. This approach enables communication with the main industrial fieldbuses present on the installation when the appropriate card is fitted, and facilitates exchange of setpoints and diagnostics with the programmable logic controller or the numerical controller in use. The range's consistency contributes to reusing programming and parameterisation standards across a heterogeneous machine park.

Commissioning is carried out using the manufacturer's configuration tools, with methodical guidance for the essential motion-control parameters. The speed, torque and position control functions are tuned according to load and cycle requirements. This methodology reduces commissioning time and improves the dynamic behaviour of the axis. In operation, repeatability of profiles and stability of control loops contribute to process quality, while the modular structure of the 9300 series simplifies keeping systems operational.
