Description
Servoster-05 is an all-purpose electronic servodriver dedicated to control actuators working in modulating mode, both executing regulatory and on-off tasks. It performs contactless remote control of electric drives with three-phase electric motors up to 7.5kW. It supports main logic and linking features required for regulatory and controlling servomotor:
➡ contactless switching and reversing service duty of servomotor’s engine during heavy-duty action,
➡ remote motor’s slow down with energy recovery,
➡ three-points control duty directly from PLC driver, control panel or system,
➡ automatic servomotor stoppage in ultimate positions,
➡ automatic servomotor stoppage in absence of electric standby,
➡ co-operation with limit and torque switches and motor’s thermostat,
➡ duplication of limit switches,
➡ duplication of regulatory state and working mode,
➡ control signals’ hold up until drive reaches extreme position,
➡ hold up drive’s lock at terminal stop until reverse control signal appears,
➡ interaction with control panel or local control box,
➡ servicing of emergency stop button and additional block systems,
➡ LED signalling of servomotor’s field state and electric standby,
➡ internal protection against short circuits and phase’s fading.
