Electro-Sensors, Inc. Synchronous Controller for Motor Drives MS332

Synchronous Controller for Motor Drives Features • Index-follower (event/phase synchronization), Ratio-follower (electronic line-shaft) and Master modes • Smooth, tight closed-loop PID control re-calculates 1024 times/s • 6 digit setpoint precision with full decimal point flexibility • Follower modes maintain locked synchronization per the setpoint with zero average error • Multiple switchable/selectabl e setpoints per mode • Many configurable switch-input and transistor- output functions aid sophisticated machine control processes • Special features including encoder pulse per index measurement and averaging (Index-follower mode) • Setup, calibration, and diagnostic utilities • Standard Modbus RTU over RS485 network interface allows remote access to all configuration parameters and real-time measurements The MS332 is a powerful and versatile tool for building numerous closed-loop follower machine processes. The MS332 creates an intelligent follower control loop by receiving event-index and/or shaft encoder sensor signals from both the lead and follower machines and outputting an analog speed command to your follower machine variable speed motor drive. Capabilities include uni/bi-directional machine speed and mechanical phase control, event synchronization and electronic line-shaft/gearing. Accepts quadrature incremental encoder signals and virtually all type discrete index/event sensor signals (e.g. encoder Z, prox, photo-eye, logic). Provides encoder/sensor power, making it ideal for new or existing systems. The isolated analog speed command output is configurable to 0 → ±10V bi-directional or 0 → 10V unidirectional with or without a discrete (transistor) fwd/rev direction command, making the MS332 compatible with virtually all variable speed drives (AC-vector, AC-inverter, DC or servo).
