DC servo-amplifier Junus JSP series

digitalRS-232torque control

The JSP panel controls brush motors in torque and velocity mode. The JSP accepts both analog and PWM commands. Sensorless velocity feedback is derived from the motor back-EMF. Specifications CONTINUOUS CURRENT 5A PEAK CURRENT 10A SUPPLY VOLTAGE 20-90 VDC DIMENSIONS 130 x 82 x 31 mm DIGITAL INPUTS 5 DIGITAL OUTPUTS 1 FEEDBACK Back-EMF COMMAND INTERFACE Analog, PWM ENVIRONMENT Commercial Control Modes • Velocity, Torque Command Interface • ±10V velocity/torque command • PWM velocity/torque command Communications • RS232 Feedback • Back-EMF (velocity mode) I/O - Digital • 5 inputs, 1 output Dimensions: mm [in] • 130 x 82 x 31 [5.1 x 3.2 x 1.2] DESCRIPTION The Junus™ digital servoamplifier puts 100% digital control of DC brush motors in a panel-mounting package with power options to ±15 Adc continuous and ±30 Adc peak from +20 Vdc to +180 Vdc DC power supplies. Torque mode operation works with popular position-loop controllers that use PID filters to close a position-loop. Sensorless velocity control works with position loop controllers that only output a position-error signal such as PLC’s. Set-up is fast and automated by CME 2™ software operating under Windows®. CME 2™ communicates with Junus™ through an RS-232 link for complete amplifier setup. Auto-tuning algorithms in CME 2™ slash set up times for fast system commissioning by automating current and velocity-loop tuning. A powerful oscilloscope and signal generator display amplifier performance for fine tuning thereafter. Amplifier control parameters are saved in non-volatile flash memory. OEM’s can inventory one part, and configure amplifiers on-site to each axis in a machine.
