Product Description:
The SE20000-000000 servo drive is produced by Kollmorgen as part of the S200 Servo Drives series. It interfaces with brushless servomotors and executes torque, velocity, and position loops so factory controllers can move axes precisely without additional power stages. By converting power from a regulated DC bus into high-frequency pulse trains, the unit provides the actuator interface for packaging lines, electronic assembly equipment, and other automated stations. Its closed-loop architecture supports applications that require controlled acceleration, stable speed, and repeatable positioning under changing loads.
During continuous operation, the drive delivers 20 ARMS of output phase current and provides an apparent power rating of 7.2 kVA from a 325 VDC bus, while its internal bus is rated for 8.68 kW. Current is regulated in a digital loop sampled at 16 kHz, while the velocity loop executes at 4 kHz. Both loops operate through an 8 kHz PWM stage that produces a current ripple frequency of 16 kHz in the motor windings. Position feedback is handled by an encoder, and the receiver accepts signals up to 3 MHz. The drive powers the feedback transducer with 5 VDC at up to 250 mA. This configuration supports encoder feedback only, and the drive includes no electrical option modules for expanded I/O.
Short bursts are supported by a peak output current of 40 ARMS for up to 2 seconds, after which current foldback begins to protect the power stage. Power losses produce 240 W of heat that must be removed through panel airflow or conduction to a heat sink plate. An internal sensor initiates a protective trip at 90 °C to prevent excessive semiconductor temperature. The DC bus is disconnected if regenerated energy raises the link voltage above 430 VDC. Adequate cabinet clearance and ventilation are necessary to keep the drive within its operating temperature range during sustained loading. Regenerative conditions must also be managed so decelerating loads do not repeatedly trigger the bus overvoltage protection.
