your reliable partner

O mayr your reliable partner ROBA-stop®-S have two functions. During standard operation they work as holding brakes. When the drives have been switched off, the brakes hold the system safely in position. During critical operational situations, e.g. with EMERGENCY STOP or power failure, ROBA-stop®-S are designed to absorb peak loads with high friction work. These brakes are designed for vertical and horizontal operations. Dust and waterproof Completely enclosed brake design corresponds to Protection IP 67. Brake housing and integral terminal box Optimum protection for electrical equipment...

your reliable partner Friction Power Diagrams Permitted Brake Friction Work The permitted friction work dependent on the switching frequency, as shown in the characteristic curves (pages 6 and 7) must not be exceeded. Diagrams 1 and 2 show the permitted friction work Qperm for the various brake sizes and speeds (1750 rpm with brake Sizes 8 – 10 and 1000 rpm with brake Size 11) with reference to the switching frequency on which it is based. Diagram 1: ROBA-stop®-S Sizes 8 - 10 / Type 856.417._ 1 000 000 Conditions: Speed: 1750 rpm Brake 100% duty cycle. Mounting brake without cooling...

your reliable partner Qperm Permitted friction work [J] Conditions: Speed: 1000 rpm At higher speeds, the friction work reduces acc. diagram 3. Brake 100% duty cycle. Mounting brake without cooling current. Qperm Permitted friction work [J] For higher speeds than 1000 rpm (Size 11): Please observe diagram 3! Design example for a speed of 1250 rpm: Permitted friction work Qperm for 1250 rpm from diagram 3: 300 000 J. This value limits the permitted friction work Qperm acc. diagram 2 for low switching frequencies (here up to 3,5 switchings per hour). The permitted friction work Qperm reduces...

your reliable partner Replacing Worn Parts The rotor (4), the armature disk (5) and the gear hub (1) are parts which are subject to wear. 1) At first, please follow the same procedure as in “Air Gap Re-Adjustment”: - Sizes 8 – 10 according to points 1 – 4 - Size 11 according to point 1 2) Check the parts subject to wear and replace them if necessary. • Replacing the rotor: - Size 11: Attach the adjusting plate (28) to the housing (27) using the cap screws (28.1). (Adjusting plate and cap screws are part of the replacement rotor delivery). - Sizes 8 – 11: Replace the rotor (4). - Sizes 8 –...

your reliable partner Guidelines on the Declaration of Conformity: A conformity evaluation has been carried out for the product (electromagnetic safety brake) according to the EC Low Voltage Directive 2006/95/EC. The conformity evaluation is set out in writing in a separate document and can be requested if required. Guidelines on the EMC Directive (2004/108/EC): The product cannot be operated independently according to the EMC Directive. Due to their passive state, brakes are also noncritical equipment according to the EMC. Only after integration of the product into an overall system can...
