Safety module SM301 V1.3
Functional description
Previously, the standstill function (STO according to SS1 or SOS according to SS2) was never activated until after expiry of the stopping time.
Due to the setting 'STO when n=0' respectively 'SOS when n=0', STO respectively SOS is activated as soon as the speed falls below the 'tolerance window (n=0)'.
If the function is used in conjunction with SS1, a delay time can still be parameterised. This makes it possible for a brake to be applied before STO is activated. This is especially important in the case of hoists.
Applications
In applications where the motor turns slowly when SS1 or SS2 is activated and where it is braked with constant deceleration or is even already at a standstill, the cycle time of the machine is reduced because it is not necessary to wait for the stopping time to expire before, e.g., a safety door can be unlocked.
Engineer V2.10 is necessary in order to make use of the extended function.
