Description
Kollmorgen, Digital Servo Amplifier, 208 to 480 V ac, 6 A
The Kollmorgen Servostar 346 (S30601-NA) is a digital servo amplifier from the Servostar S300 family, used to drive brushless synchronous and asynchronous servo motors.
It acts as the drive stage for a single servo axis, taking a command signal and delivering controlled current to the motor, with onboard resolver and encoder inputs so it can close the position and speed loop from the motor’s feedback device. The CAN interface and two analog inputs let it fit into a wider machine control scheme, and its compact footprint saves cabinet space.
- Manufacturer: Kollmorgen (Servostar S300 family; also branded Seidel / Danaher Motion)
- Type: Digital servo amplifier
- Supply voltage: 3 x 208 to 480 V AC +/-10%, 50/60 Hz
- Auxiliary supply: 24 V DC
- Output current: 6 A rated, 12 A peak
- Power: approx. 4 kW (5 kVA)
- Feedback: Onboard resolver and encoder inputs, CAN interface, two analog inputs
- Protection / size: IP20, approx. 246 x 70 x 171 mm, 2.86 kg
The S300 family is obsolete but still common on production machinery, so amplifiers are sourced and repaired rather than replaced wholesale. Because the amplifier must be matched to the motor’s feedback type, confirm your motor and feedback device before ordering.
