The CMGA from Festo is 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 switchoff 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.
