ROBA®-topstop®
ROBA®-topstop®
Modular safety system for mounting onto A-bearing-side servo motors
Performance characteristics
• Axes are held safely in any position even when the servo motor is disassembled, e.g. during machine maintenance
• Optimum braking system for vertical axes and when handling large weights
• Long lifetime even after frequent EMERGENCY STOP brakings
• Integrated switch signalises the operating condition (not braked/braked)
• Short, compact construction
• Low device weight (light metal housing)
• Low protection of heat even at 100 % duty cycle
□ Single circuit brake with bearing-supported output shaft, meaning that it can also be used for toothed belt drives.
□ Single circuit brake with integrated, insertable shaft coupling.
□ Single circuit brake with shaft coupling and integrated EAS®-smartic® torque limiting clutch.
□ Redundant dual circuit brake with bearing-supported output shaft.
□ Basic brake module for special brake configurations.
Due to their adapted flange dimensions, ROBA®-topstop® safety brakes can be easily integrated in existing constructions between the servo motor and the counterflage. If necessary, a design for any installation situation can be implemented by replacing the standard flange.
Three standard construction sizes for braking torques from 12 to 160 Nm are available at short notice.
Braking system with integrated, insertable shaft coupling. Separate coupling and coupling housing no longer necessary.
ROBA®-topstop® with output shaft for direct mounting onto a gearbox with a hollow shaft.
