A permanent overview of the brake operating conditions
Innovative monitoring solutions for safety brakes
The monitoring of electromagnetic safety brakes is an increasingly important topic. mayr®power transmission is therefore setting new standards with the new, intelligent brake control module ROBA®-brake-checker. This module is not only able to energise brakes, but can also monitor them without the use of sensors. It is flexible and easy to integrate into existing systems.
As the amount of networking between people, processes and machines increases, the requirements on the individual components of a drive line also rise. mayr®power transmissionhas therefore risen to the current challenges set by the Industry 4.0. andhas already incorporated into its range intelligent products which can communicate with the superordinate controls. The latest developments include an intelligent brake control module, the ROBA®-brake-checker, which is not only able to energise safety brakes, but also to monitor them without the use of sensors. It recognizes the switching condition of the actuator and the wear on the brake linings, and thus detects safety-critical conditions prior to their occurrence. Any changes in the braking torque can thus be instantly detected and countermeasures initiated – for maximum functional and operational safety.
Higher performance, less inconvenience
The new module ROBA®-brake-checkerserves to operate safety brakes at reduced powerwhile simultaneously monitoring their switching condition. It is designed for an input voltage of 24V or 48V DC, and can control brakes with a coil nominal current of 10A or 5A. In comparison to the previous fast acting rectifiers, the new module is characterised by its higher performance and also by a larger input voltage range of 18-30 VDC or 42-54 VDC and a controlled output voltage atreduction.In addition, ahigher cycle frequency is possible. The moduleROBA®-brake-checkerreliably detects when the brake condition changes; i.e. whether the armature disk has been attracted or released. The module emits the respective switching condition of the brake via a signal output. With the ROBA®-brake-checker, the switching condition of safety brakes can therefore be recorded in machines and systems even without the usual microswitches or proximity sensors.
The module functions highly reliably without mechanical contacts andis wear-free, independent of the cycle frequency and count.The additional wiring and possible sealing of switches and sensors is therefore no longer required. In addition, it is possible with the sensorless condition monitoring to adapt the overexcitation time automatically if required. Here an integrated automatic system regulates the voltage to the set lowering voltage after a brake-specific overexcitation time. Using a DIP switch, the automatic system can be switched off, after which it is possible to set certain, specified values manually.
Detect errors before they occur
Through the comparison of tightening current and holding current, the module ROBA®-brake-checker is able to detect a possible wear reserve or line breakage, or, if applicable, to detect unpermitted heat-up.In this way it can reveal safety-critical conditions and errors prior to their occurrence, and thus guarantee maximum operational safety for machines and systems. The new monitoring module can be used for a wide range ofROBA-stop®brakes, and can be easily, quickly and inexpensively integrated, also into existing systems. With its compact dimensions of30 mm in height, 69 mm in width and 73.6 mm in length, it can easily be integrated into control cabinets.
Braking movements with intelligent systems
For applications which require braking torque control in addition to condition monitoring, mayr®power transmissionprovides the braking torque control module ROBA®-torqcontrol. It features the properties of the ROBA®-brake-checker, and is additionally able to change the level of braking torque during operation through the targeted influencing of current and voltage. In this way, devices and machines can be evenly and gently decelerated. The module ROBA®-torqcontrol allows control circuits to be constructed and movements to be braked intelligently – ideal prerequisites for use in smart, networked machines.
