SAM-DA-400-07N-P5N-F Danaher Motion SAM Series 400V Servo Amplifier

Detailed Description SAM-DA-400-07N-P5N-F is a high-performance digital servo amplifier from Danaher Motion (Kollmorgen) SAM Smart Axis Manager series, designed for three-phase 400~480V AC power supply and multi-axis synchronized motion control systems. Widely adopted in printing machinery, textile equipment, packaging production lines and special heavy-duty automation machines. This P5N-F version uses fiber optic EasyBus for inter-axis high-speed synchronization, paired with Profibus DP fieldbus interface to realize reliable communication with upper PLC controllers.

This servo amplifier adopts high-speed DSP closed-loop control algorithm, supporting position, speed and torque three core control modes. It is compatible with resolver, incremental encoder and absolute encoder feedback devices to match different servo motor feedback configurations. The front panel is equipped with 7-segment digital display and LED status indicators, showing running data and fault alarm codes, helping maintenance personnel quickly locate on-site faults. It reserves abundant digital safety I/O terminals for hardware enable signal, hardware over-travel limit, fault relay output and positioning completion feedback. The drive supports external braking resistor connection for dynamic energy dissipation under fast deceleration and high inertia load working conditions.

Built-in comprehensive protection functions include overcurrent, overvoltage, undervoltage, overheat, motor overload, encoder error and short-circuit protection. Once abnormal signals are detected, the amplifier immediately cuts off power output and triggers alarm to protect the servo amplifier and matched servo motor. It adopts vertical cabinet installation with IP20 protection grade, operating temperature range from 0℃ to 60℃, and has strong anti-electromagnetic interference capability, adapting to industrial workshop environments with vibration, dust and oil mist. The fiber optic EasyBus network can connect multiple SAM drives to achieve rigid multi-axis synchronous motion, supporting up to 127 axes networked within one single system. Compared with copper bus variant, fiber EasyBus effectively eliminates electromagnetic interference between axes, delivering more stable synchronization in high-noise industrial sites.

SAM-DA-400-07N-P5N-F is discontinued legacy Danaher industrial spare part. A large number of old multi-axis automation production equipment still rely on this SAM series servo system. When the original amplifier fails, replacing it with identical SAM-DA-400-07N-P5N-F can reuse existing servo motors, encoder cables, power wiring and saved servo parameter settings. No modification of PLC motion program or mechanical structure is required. Technicians only restore backup parameters without complicated servo loop re-tuning, so the machine can resume production rapidly and reduce downtime.

Before shipment, every SAM-DA-400-07N-P5N-F undergoes comprehensive functional inspection including power-on startup test, fiber EasyBus communication verification, Profibus bus test, encoder feedback check, JOG motor running test and protection function simulation. We verify alarm output stability and parameter saving function. All products come with 12-month warranty. Our automation technical team provides remote support for wiring guidance, parameter backup, multi-axis synchronization configuration and fault diagnosis. Fast global shipping is available for urgent maintenance orders.

For automation maintenance engineers and system integrators, SAM-DA-400-07N-P5N-F is a reliable spare servo amplifier for legacy Danaher SAM multi-axis motion systems. It retains original multi-axis synchronization and positioning precision of equipment, extends service life of automation assets and avoids high-cost full motion control system renovation.
