Product Details:

KOLLMORGEN SR20201-000000 is a rack-mounted single-axis digital servo amplifier of the SERVOSTAR SR20 series with standard resolver feedback configuration. It supports 230VAC single-phase power input, 20A continuous current and 40A peak current, adopting high-performance IGBT power stage and full digital closed-loop control algorithm. It accepts analog ±10V speed and torque command input, supports automatic load tuning, and integrates internal motion task storage for homing and indexing operations. It is widely matched with Kollmorgen Goldline permanent magnet servo motors and applied on heavy-duty CNC axes, printing presses, large rotary indexing tables and packaging automation production lines, suitable for medium-heavy load motion control scenarios requiring high torque output and reliable low-speed stability.

This servo amplifier uses resolver as the primary feedback component, which maintains stable signal acquisition in dusty and oil mist industrial workshop environments. It is equipped with RS232 service port for parameter setting, auto-tuning and firmware upgrade via Kollmorgen MotionLink software. It integrates built-in dynamic braking circuit for energy dissipation during deceleration, and supports external brake resistor connection for frequent high deceleration cycles. Separated power terminals and resolver feedback connectors facilitate shielded wiring and on-site maintenance. Onboard diagnostic functions and LED status indicators help technicians quickly locate alarms such as overcurrent, overtemperature and feedback loss.

Professional technicians can adjust loop gain, current limit and motion parameters according to load characteristics. Internal circuits continuously sample DC bus voltage, output current and module temperature. Once overload, overheating, overvoltage or resolver signal interruption is detected, the drive will cut off power output and trigger alarm to protect servo motor windings and resolver components. The mechanical structure is robust and vibration-resistant, suitable for long-cycle continuous operation of industrial automation equipment.

This KOLLMORGEN SR20201-000000 servo amplifier has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy Goldline motion systems. Maintenance personnel can complete replacement safely after power cut, and the original motor interface and rack installation dimensions can be retained without large modification.

It is a standard SR20 series high-current servo drive spare part, frequently selected for maintenance and retrofit of old CNC and heavy automation equipment.
