System function and position

Rebuilt from individual evidence

Radwell identifies EVS9321-EPV004 as a Lenze 9300 servo position controller.

The listing specifies 400/480 VAC, 0.37 kW, a built-in unit design, and a safe-standstill variant.

The controller sits between the machine controller, feedback devices, and a servo axis to regulate position-related motion.

Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate confirmation for EVS9321-EPV004.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Controls a servo axis with position-oriented drive regulation.
System position: Sits in the servo-axis control chain between the machine controller, feedback, and the power stage.
Upstream / inputs: Receives motion commands and axis feedback within the configured servo system.
Downstream / outputs: Applies controlled drive output to the connected servo motor.
Limitations: Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate confirmation for EVS9321-EPV004.
