Delivering 22.0 kW of precise motion control, the Lenze EVS9328-EPV004 serves as a high-performance servo position controller within the legacy 9300 Series architecture. This unit is engineered to execute complex positioning profiles, speed control, and torque-matching tasks in demanding industrial environments. Featuring an IP20 protection rating, it is designed for clean-room or control-cabinet installation, integrating seamlessly with master PLC systems via dedicated fieldbus interfaces and analog/digital I/O channels.

The EVS9328-EPV004 is a dedicated positioning controller ("EP" variant). It is not directly interchangeable with standard speed controllers ("ES" variants) or register controllers ("EVG" variants) without modifying the PLC control logic and parameter sets. When replacing legacy units, ensure that the AIF communication module (such as the EMF2102IB or EMF2133IB) is transferred to the new unit and that the firmware revision matches to prevent communication timeouts with the master controller.
During highly dynamic deceleration cycles, the internal DC bus voltage can rise rapidly. If the system experiences frequent "OU" (Overvoltage) faults, verify that an external brake resistor (Lenze CHO series) is properly sized, connected, and configured in the parameters. Ensure the control cabinet has adequate forced-air ventilation, as the 22.0 kW unit generates significant thermal dissipation under continuous peak torque demands.
Always use double-shielded twisted-pair cables for resolver and encoder feedback connections to prevent high-frequency noise injection from the motor power lines. Ground the motor cable shield at both ends using low-impedance EMC shield clamps. Parameterization can be performed using Lenze Global Drive Control (GDC) software via the AIF interface; ensure the baud rate of the PC adapter matches the drive's default serial settings before attempting connection.
CRITICAL WARNING
Hazardous electrical voltages remain present in the DC bus capacitors for up to 5 minutes after disconnecting the mains power supply. Measure the voltage between terminals +UG and -UG to ensure it has dropped below 50 VDC before performing any wiring, maintenance, or module replacement tasks.
Mount the servo controller vertically inside an IP54 or higher rated control cabinet, leaving a minimum of 100 mm clearance at the top and bottom for unobstructed cooling airflow.
Connect the protective earth (PE) conductor to the central ground busbar of the cabinet before making any other electrical connections.
Wire the three-phase AC mains supply to terminals L1, L2, and L3 through an appropriately rated circuit breaker and line filter.
Connect the motor phases to terminals U, V, and W, ensuring correct phase rotation to prevent uncontrolled runaway conditions during commissioning.
