Normal
behaviour
During the stopping time elapses, or before the tolerance window (n=0) is reached, the speed
ramp parameterised is not exceeded. Afterwards there is the transition to the STO or SOS stop
function parameterised.
Error behaviour If the current speed exceeds the parametersed speed ramp within the stopping time or before
the tolerance window (n=0) is reached, an error message is triggered and an error stop is
activated.
• The power supply for the motor is safely interrupted immediately ( STO ). The motor cannot
generate a torque and thus no dangerous movements of the drive.
