KOLLMORGEN PR204-099-520 Servo Drive Amplifier

Overview

The KOLLMORGEN PR204-099-520 is a PRD series servo drive amplifier manufactured by Kollmorgen, designed for AKM series synchronous servo motors. The KOLLMORGEN PR204-099-520 accepts analog ±10V speed or torque command signals from host controllers, and provides high-precision closed-loop current, velocity and position control for automated machinery. It reads encoder feedback signals from the servo motor and outputs power to the motor winding to achieve accurate motion positioning. The KOLLMORGEN PR204-099-520 is an obsolete legacy spare, widely stocked for maintenance and replacement of existing machine tool, packaging and material handling motion control cabinets.

Features

The KOLLMORGEN PR204-099-520 supports resolver and incremental encoder feedback interfaces for flexible motor matching. It integrates overcurrent, overvoltage, undervoltage, overtemperature and motor short-circuit protection functions. The KOLLMORGEN PR204-099-520 includes analog setpoint input, enable signal and fault relay contact output for easy interconnection with PLC and CNC systems. It has built-in LED diagnostic indicators for power, drive enable and fault status. The KOLLMORGEN PR204-099-520 follows standard DIN rail mounting and terminal pin definition, supporting direct plug-in replacement for the same PRD series drive units.

Specs

Device Type: PRD series servo drive amplifier Model: KOLLMORGEN PR204-099-520 Applicable Motor: Kollmorgen AKM series servo motor Control Mode: Torque control, speed control, position control Feedback: Incremental encoder / resolver Command Input: ±10V analog signal Power Supply: 230V AC single phase Mounting: 35 mm DIN rail mount Protection Grade: IP20 Application: CNC machine tool, packaging machine, material handling, special automation equipment

Principle

The KOLLMORGEN PR204-099-520 receives analog command signals from the upper control system. The internal control board compares the command value with the actual motor speed and position fed back from the encoder, then adjusts the PWM output to the power module to drive the servo motor. The drive continuously monitors bus voltage, output current and internal temperature. When overload, overheat or encoder signal loss is detected, the KOLLMORGEN PR204-099-520 disables the power stage, triggers fault relay and stores the fault code for diagnosis.

Applications

The KOLLMORGEN PR204-099-520 is used for single-axis motion control on CNC lathes, grinders and automated assembly lines. It serves precise positioning and speed regulation for packaging and converting machinery. The KOLLMORGEN PR204-099-520 applies to spare stock and emergency repair of legacy Kollmorgen PRD motion control cabinets. It also supports retrofit projects for old servo axis renovation.
