Technical FAQs

Does the EVS9324-ESV004 support regenerative braking?

Yes. For applications with high-inertia loads or frequent deceleration, the drive can be equipped with an external brake resistor. The internal brake chopper manages the energy dissipation to prevent DC-bus overvoltage faults during aggressive braking cycles.

Which feedback systems are compatible with this servo inverter?

The 9300-Series typically supports resolvers as standard feedback. However, with additional plug-in modules, it can interface with SinCos encoders, incremental encoders, or SSI absolute encoders, providing flexibility for various precision requirements.

How can I transfer parameters to a replacement unit?

Parameters can be transferred using the plug-in keypad (EMZ9371BC) which features a "copy" function, or via a PC using the Lenze Global Drive Control (GDC) software and a suitable communication adapter.

Engineering & Installation Guide

For successful integration of the EVS9324-ESV004, ensure the unit is mounted vertically with a minimum clearance of 100 mm above and below the chassis to allow for adequate airflow from the internal fan. To comply with EMC directives, motor cables must be shielded and the shield must be grounded using 360-degree clamps at both the inverter’s EMC plate and the motor's terminal box. Avoid mixing control wiring with high-voltage power cables in the same trunking to prevent signal interference. If the drive is used in a multi-axis system, consider a common DC-bus connection to allow for energy sharing between motoring and braking axes, which improves overall energy efficiency. Before full-load operation, perform a motor identification (auto-tuning) procedure to ensure the inverter's current control loops are perfectly matched to the motor's electrical characteristics.
