BN6751.3817 belongs to ESR Pollmeier TrioDrive D servo family, model BN6751 variant .3817. Mains supply single-phase 230V AC ±10%, 50/60Hz, DC link 320V. Rated output current 2A, peak current 5.5A, suitable for servo motors up to 0.5kW and 1.0Nm continuous torque. Control power 24V DC ±20%, 0.8A. Switching frequency 16kHz for smooth motor operation and low acoustic noise.

This servo amplifier integrates RS232C serial port as standard for parameter setup and commissioning. Optional communication modules support CANopen, Profibus-DP or Interbus for connection to PLC or motion controller. It accepts pulse/direction commands or fieldbus setpoints, operating in position, speed and torque modes. Digital inputs and outputs are provided for servo enable, alarm output, positioning complete and limit signals. It supports incremental encoder feedback and can be tuned via Pollmeier PC software for gain optimization. Built-in brake chopper interface allows external braking resistor connection for fast deceleration.

Comprehensive protection functions include overcurrent, overload, overvoltage, undervoltage, drive overtemperature, encoder fault, short-circuit and earth fault protection. IP20 protection grade for cabinet mounting, operating temperature range 0~50℃.

BN6751.3817 is discontinued legacy ESR Pollmeier servo spare part. Many old automation machines still run TrioDrive D servo systems. When the original drive fails, replacing it with identical BN6751.3817 can reuse existing servo motor, power cable, encoder wiring and original servo parameters. Technicians complete wiring, parameter restore and JOG test, so the machine positioning axis resumes operation and reduces downtime.

Before shipment, every BN6751.3817 undergoes comprehensive functional inspection including power-on self-test, I/O signal test, encoder feedback test, output waveform check and protection function simulation. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, servo parameter tuning and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, BN6751.3817 is reliable spare servo amplifier for legacy ESR Pollmeier TrioDrive D motion systems. It restores high-precision axis positioning and dynamic motion performance, extends service life of automation assets and avoids high-cost whole servo system renovation.
