MS332 Synchronous Controller Features: • • • • • • • • • Compatible with all variable-speed drives Keypad/display menus and features Setup, calibration and diagnostic utilities Special features including pulse per index measurement and averaging Master, ratio-follower, and index-follower modes Multiple set-points Switch-input functions NPN-output functions Serial Modbus communications R Description The MS332 is a powerful and versatile tool for building numerous closed-loop processes. Closed-loop control capabilities include speed and phase control, electronic line shaft/gearing, event synchronization, and bi-directional control. The MS332 accepts quadrature encoder signals and almost any type of index/event sensor signal. The controller also provides the encoder/sensor power, which makes the MS332 ideal for new or existing systems. The MS332 supplies an isolated 0 ±10 VDC speed reference signal to the drive, making it compatible with virtually any variable speed drive (AC, DC, or servo). Operating Modes Index Follower The MS332 automatically phases the feedback and lead event pulses to precisely synchronize events. Dissimilar encoders and shaft speeds work together without error. Feedback, lead, and event-pulse signals input to the MS332. Application Diagrams Superior · Systems · Solutions Event pulses are commonly generated by proximity and photoelectric sensors, although other sources may be used. The follower phase set-point may be entered or determined by advancing/retarding the set-point on-the-fly. Ratio Follower The MS332 achieves true electronic gearing by precisely setting follower ratio to master speed, resulting in zero cumulative error. Dissimilar encoders and shaft speeds work together without error. Feedback and lead signals input to the MS332. The user enters the follower/master speed ratio and may change it on-the-fly. Master The MS332 maintains the desired set-point speed. Feedback signal inputs to the MS332. The user may easily change the set point by entering the desired new value into the front panel keypad.
