Product Description:

The H-342-H-0200 is a brushless servo drive supplied by Kollmorgen in the Silverline Brushless Servo Drives series. It regulates three-phase permanent-magnet servomotors in automated equipment by converting DC bus energy into precisely timed phase currents. The module provides accurate torque and speed control for packaging stations, pick-and-place robots, and electronic assembly cells where coordinated motion is required.

Its continuous output capability is 470 W, meaning the drive can deliver almost half a kilowatt to the motor without overheating during rated operation. To sustain that load, the power section draws 12.0 A DC of current, which must be considered when selecting fuses and cables. The system can produce 1.26 N·m of stall torque, allowing tables or slides to remain fixed when stopped. The drive accepts up to 250 V RMS between the motor leads, so operation with standard 230 V industrial supplies is possible. Commanded velocity is followed at speeds up to 6000 rpm, enabling high cycle rates. The back-EMF constant is 12.5 V peak per krpm, while the winding has an inductance of 1.53 mH and a resistance of 0.318 Ω. These electrical values affect current-loop response and winding losses during operation.

Acceleration bursts are supported by 2.65 N·m of peak torque, while the phase current can rise momentarily to 28.0 A DC. The rotor has an inertia of only 0.000048 kg·m², allowing rapid speed changes, and its torque sensitivity of 0.105 N·m per amp provides predictable response. Position feedback enters through a 10-pin ribbon connector that carries signals from a 1000-line encoder for precise motion sensing. Heat moves from the windings to the housing through a thermal resistance of 1.7 °C/W. An 11.4-minute thermal time constant slows internal temperature changes under transient loads, supporting repeatable motion in tightly packed multi-axis machines.
