easySafety
In this example, the activation coil ZM01SA is always active.
ZM01QS switches the safety marker MS01 in the event of a
standstill. If the speed of the motor is greater than 2 Hz, the
contact ZM01QS opens and sets the safety marker MS01 to
logic 0. The function block inputs ZM01I1 and ZM01I2 do
not have to be wired as these are automatically connected
with device inputs IS01 and IS02.
