EVS9326-EPV004 Lenze 9300 Series 11 kW Servo Position Controller

、

Product Overview

The EVS9326-EPV004 (EVS9326-EPV004) is a high-performance servo position controller from the Lenze 9300-Series, specifically engineered for precision-heavy motion control in complex automation environments. With a substantial rated power of 11.0 kW, this drive is a critical component for high-torque applications such as industrial winders, automated gantry systems, and heavy-duty rotary tables. The "EP" designation identifies this unit as a specialized positioning controller, capable of handling sophisticated path control and synchronized motion independently of the central PLC. This reduces the processing burden on the main control system and minimizes communication latency. Although currently in its "Phase-Out" stage, the EVS9326-EPV004 remains a cornerstone for maintaining legacy industrial systems where 11 kW of reliable, dynamic motor control is essential for preventing unscheduled downtime and maintaining production throughput.

Technical Configuration

The EVS9326-EPV004 features a high-density power stage optimized for a 3-phase mains connection. Its internal architecture is centered on a high-speed digital processor that supports advanced features like electronic cams, internal positioning profiles, and multi-axis synchronization via the integrated system bus. The unit's IP20-rated enclosure is designed for vertical installation within electrical cabinets, utilizing an efficient thermal management system to handle the heat dissipation generated by 11.0 kW of continuous operation. The controller supports multiple feedback systems, including resolvers and high-resolution encoders, ensuring precise closed-loop control. Furthermore, its modular interface allows for the addition of fieldbus communication modules, making it a flexible solution for both standalone positioning and complex networked automation systems.

Technical FAQs

How does the "EP" version differ from a standard 9300 inverter?

The EVS9326-EPV004 includes an integrated positioning control module. While a standard inverter primarily controls speed or torque, the EP version handles absolute and relative positioning, including home positioning (homing) and point-to-point motion, directly within the drive's firmware.

Is it possible to migrate the parameter settings from a failed unit to a replacement?

Yes. Parameters can be transferred using the Lenze Global Drive Control (GDC) software or via a portable keypad module. Ensure that the firmware revision of the replacement unit is compatible with the original parameter set to prevent logic errors during commissioning.

What cooling measures are required for this 11.0 kW controller?

The unit relies on forced-air cooling via its internal fans. It is essential to ensure that the cabinet's ambient temperature remains within 0 to 45 deg C and that the vertical airflow path is unobstructed to prevent thermal tripping during high-duty cycle operations.

Engineering & Installation Guide

• Thermal Management and Clearance: Given the 11.0 kW power rating, heat dissipation is significant. Maintain a minimum vertical clearance of 100 mm above and below the drive. For side-by-side installations, verify the current derating factors if the drives are mounted with less than 10 mm of lateral space in cabinets with limited ventilation.

• Shielding and Signal Integrity: To prevent electromagnetic interference (EMI) from affecting the positioning accuracy, use high-quality shielded motor cables. The shield must be connected to the PE rail using a large-surface contact at the drive end. Avoid running feedback (encoder/resolver) cables parallel to high-power motor leads to prevent signal noise.

• DC Bus Safety Protocols: When performing maintenance, remember that the internal capacitors retain a high-voltage charge after power-off. Wait at least 10 minutes for the DC bus voltage to discharge below 50 VDC. Always measure the voltage between terminals +UG and -UG with a calibrated multimeter before touching any connections.
