In line with the new safety regulation being rolled out across Europe, Festo has launched a range of safety components. The latest of these is the CMGA, a compact safety system with the option of integrated drive monitoring for one axis. It monitors safety switches or speed and position transducers, for example. Preconfigured software modules are available for processing safety-relevant signals.
Whether for an emergency stop, two-hand button, operating mode selector switch or safe standstill, systems equipped with the safety system CMGA meet the requirements of the Machinery Directive and the Performance Level (PL) to EN ISO 13849-1. The basic design of the device has 14 safe inputs and three switch-off channels, which can be extended to 65 safe I/Os.
There are modules with integrated encoder interface for safe speed and position sensing. The safety system CMGA, which is certified by TÜV Rheinland, ensures compliance with requirements up to Cat. 4, PLe and SIL3.
It is configured using the Festo Editor for Safety software tool. It not only includes the preconfigured safety modules such as emergency stop or guard door, but also the functions for safe drive technology standardised to EN 61800-5-2 such as SS1, SS2, SOS, SLS, SLT, SLP or SDI. Fieldbus modules for Profibus, CANopen and DeviceNet are available for communication with the standard controller.
