For example, if during active Safe Limited Speed (SLS) speed monitoring the previously parameterized speed is exceeded, the delay time is started. The safety module simultaneously sends a signal to the converter to perform a specific action. This action can be parameterized in advance; for example, the converter decelerates the drive in a controlled manner within the set time. Only when the machine has come to a standstill is the drive safely switched torque-free.
The parameterizable delay time is a time window, individually user-programmable depending on the safety function, which is switched between the safety functions and the STO function. Now available for all SAF 002/003 safety modules of the b maXX 5000 converter series.
