Product Overview

SA5400 Brushless amplifiers

SA5400 AC Brushless Servoamplifier

SA5400

SA5400 Servoamplifier and matching line of M5400 Servomotors were specifically developed to address retrofit market place for older machines employing large Brush DC and Brushless AC servomotors and amplifiers no longer supported by original OEMs. SA5400 was designed with versatility and flexibility in mind. State of the art design using 3-D modeling software, High Torque, MS connectors interface, various choice of feedback devices( tachometer, resolver, Encoder) matching motors and cables makes a low cost alternative to major machine retrofit as well as great solution to new OEM applications such radars and antennas, material handling and CNC machines.

Capabilities

USD is ideal single axis drive with extended kit of functions and embedded system of graphical programming which allows to built applications for majority of technological processes where it is needed fast setup&run.

Features	Benefits
Field weakening mode	Extended speed range of motor
PLC with graphical programming language	Adaptation for logics of technological process without external PLC. Program can be created as block-diagrams, text, state-machines, algorithms and can use any events and digital/analog inputs for calculation of position/speed/torque command and digital/analog outputs as well as the values of all drive parameters.
Auto alignment	Servo motor compatibility for commutation with different motor feedback types.
External shunt resistor connection	Work for high-dynamics drive
Configuration software for PC	Fast tuning for different types of motors, regulators tune in auto- and manual mode, monitoring drives coordinates, parameters tune, 2-channel oscilloscope, system diagnostics
Log of faults and events	NV-memory storing of events history during drive work, with indication of time and sensors value (temperature, DC-bus voltage, load current, etc.)
Configurable protections	Following error, OverVoltage, Undervoltage, OverCurrent, Short Circuit, I2T, OverTemperature, Hall Sensor Fault. Mode of faults reset: auto (with automatic motor start), manual. 4 modes of faults indication and stop.
Acceleration/deceleration profile	Linear, S-curve, acceleration limitation (option)
Encoder outputs	Convert drives coordinates to TTL-encoder signals for integration into motion control systems
Built-in generators	Fast tune of velocity and position regulators
Ethernet auto-search mode	Fast connection to drive and easy configuration
