Acvaon
•
If the s
top funcons SS1/SS2 are requested, a monitoring ramp is calculated and placed
o
ver the current speed characterisc.
Normal behaviour
While the stopping me elapses or before the tolerance window (n = 0) is reached, the para-
meterised speed ramp is not exceeded. When the stopping me has elapsed or the parame-
terised speed ramp has been exceeded, the parameterised stop funcon STO or SOS is acva-
ted.
Error behaviour
An error message and an error stop are triggered if:
•
the curr
ent speed exceeds the stopping me of the speed ramp parameterised.
•
the curr
ent speed exceeds the parameterised speed ramp before the tolerance window is
reached.
The power supply for generaong the rotang eld is safely interrupted 4Safe Torque O
(STO). The motor cannot generate torques and movements of the drive.
