Fact Sheet Operate safely and reduce system cost VLT® Safety Option MCB 150/151 and VLT® Sensorless Safety MCB 159 MCB 151 MCB 159 Ordering number MCB 150. 130B3280 coated MCB 151. 130B3290 coated MCB 159 – select this option in the configurator when ordering a new drive. Not available for retrofit. Reduce overall system cost, improve flexibility and increase productivity by enabling operators to perform maintenance safely, even while the machine is still in motion. Additional safety The VLT® Safety Option MCB 150/151 expands the integrated Safe Torque Off (STO) function of the VLT® AutomationDrive. Use the Safe Stop 1 (SS1) function to perform a controlled stop, before removing torque. Use the Safely Limited Speed (SLS) and Safe Maximum Speed (SMS) functions to monitor whether a specified speed is exceeded. When the VLT® Safety Option MCB 151 is combined with the built-in VLT® Sensorless Safety MCB 159 option, an external sensor is no longer required for safe speed monitoring. Use flexible speed control in upgraded or retrofitted applications. Connect input devices – such as guard locking switches, light curtains and emergency stops – directly to the module and eliminate the need for a separate, dedicated safety controller. Quick commissioning and wiring Visual instructions in VLT® Motion Control Tool MCT 10 ensure both fault- free wiring and that safety parameters are correctly transferred from the PC to the drive. The software also offers a dynamic commissioning report which can be used in the technical file for the machine. More advantages Integrated functional safety replaces external safety equipment Reduced space requirements Can send status messages via Fieldbus Password function Logging function Simpler feedback sensor systems Compliance with international standards Easier machine certification Drive can be powered continuously 100% integrated into the drive due to internal databus connection Feature Benefit No need to power cycle the drive after a demand on the safety system – Minimized wear on the drive Two logic safety inputs – Provide redundancy without needing an external safety module Maintenance can be performed while the machine – Minimized time and effort required for is still in motion service and installation work Safe Torque Off (STO) Integrated in the drive as standard – Increased productivity and availability – Eliminates one or more power contactors – Eliminates the need for additional feedback monitoring Safe Stop 1 (SS1) Monitors deceleration and then shuts off the torque – Machine is restarted quickly and more simply – Greater operational safety, as the machine is protected against unexpected restart Safely Limited Speed (SLS)/ Safe Maximum Speed (SMS) Monitors whether a specified velocity is exceeded – Safe protection against overspeed – Makes it possible to work safely with the guards open – Reduced set-up times thanks to a better view into the set-up area – Safe Jog function drives.danfoss.com
