2.4.7 Emergency Stop and protective door monitoring on a converter→
SS1
a) The drive is brought to a controlled standstill when the protective
door is opened. When the standstill timer runs down, the drive is
safely switched to a no-torque condition.
b) The supplementary safety function Emergency Stop causes the
drive to reach a safe, controlled standstill. When the standstill timer
runs down, the drive is safely switched to a no-torque condition.
As a result of the risk assessment, the required performance level for
both safety functions has been defined as PLr = d.
The DC link must remain energized in normal operation when the
protective door is open.
