Detailed Description TrioDrive D/PS BN 6757.4761 belongs to ESR Pollmeier TrioDrive D/xS family. D/PS indicates built-in Profibus-DP fieldbus interface. BN6757 is base model, 4761 is the full order suffix variant. It is directly powered by single-phase AC230V ±10% mains, internal rectifier generates 320V DC bus, rated output 4A rms, peak pulse current 17A, suitable for servo motors up to 1.3kW / 3.5Nm. It supports resolver, incremental encoder, Hiperface or EnDat feedback. Widely used in printing presses, slitting machines, packaging lines and linear positioning equipment.

This servo amplifier integrates current, speed and position closed-loop control. It has 8 digital inputs,4 digital outputs, 2 analog inputs and 2 analog monitoring outputs. It supports multiple operation modes: torque, speed, position, pulse/direction command, electronic gearing and flying shear synchronization. Standard RS232 port for PC commissioning software SPP; D/PS version adds Profibus-DP according to DRIVECOM profile. It supports encoder emulation output for master-slave axis coupling. Parameter setup, data backup and fault diagnosis are completed via SPP Windows software.

Full protection includes overcurrent, overvoltage, undervoltage, I²t motor overload, drive overtemperature, encoder fault, short circuit and overtravel protection. Adjustable switching frequency 8kHz or 16kHz. Cabinet-mounted IP20, operating temperature range 0~50℃.

TrioDrive D/PS BN 6757.4761 is discontinued legacy ESR Pollmeier servo spare part. Many old web handling and printing machines still run TrioDrive D/xS servo systems. Replacing with identical BN 6757.4761 can reuse existing servo motor, power cable, encoder wiring and Profibus network configuration. Technicians finish wiring, restore parameters and perform JOG test, the machine resumes operation and reduces production downtime.

Before shipment, every TrioDrive D/PS BN 6757.4761 undergoes comprehensive inspection: power-on self-test, I/O signal test, encoder feedback test, Profibus communication test, output waveform test and protection simulation. All products come with 12-month warranty. We provide remote support for wiring guidance, SPP software parameter backup, axis tuning and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, TrioDrive D/PS BN 6757.4761 is reliable spare Profibus servo amplifier for legacy ESR Pollmeier motion systems. It restores high-precision positioning and electronic cam synchronous performance, extends service life of automation assets and avoids high-cost full motion control renovation.
