Product Description:
The SAM-DA-400-28B-P4N-F is a servo amplifier produced by Danaher within the SAM Servo Amplifiers series. Installed between a motion controller and a three-phase permanent-magnet motor, the unit modulates DC-bus power into precisely timed phase currents so industrial axes accelerate, hold position, and decelerate under closed-loop command.
The power stage can deliver a continuous output of 28 A to the motor’s three windings, while logic electronics are supported by a control supply of 24 VDC. Fiber-optic communication over the EasyBus ring transfers setpoints and diagnostic data and ensures immunity to electrical noise. Front-panel status is conveyed through a Single 7-Segment display that cycles operating and fault codes without external tools. Internally, the amplifier references a minimum I/O rail of 19.2 VDC so field devices remain recognized even when control voltage sags.
Raw DC is presented to the drive on +/-/PE terminals, and thermistor feedback arrives on connector X13 so winding temperature can be evaluated before commutation resumes. Network identity is set with 2 rotary node switches, simplifying multi-axis configuration. Brake release is energized through the same 24 VDC level used for STO-designated Safety Stop0 and Safety Stop1 inputs, letting the machine builder share a protected logic rail across emergency-stop circuitry without extra converters. Three symmetrical output phases distribute torque evenly under every operating point.
Wake Industrial stocks this amplifier, can arrange same-day shipping when orders finalize before cutoff, and keeps quotations valid for 30 days so maintenance teams can align budgets before committing.
