1.3.18.2 Conditions
ƒ The SD−In4 input must be parameterised as active input for the "emergency stop"
function and the input delay for SD−In4 must be £ 10 ms.
ƒ The emergency stop function to be executed must be parameterised as STO via the
"SSE: emergency stop function" parameter.
ƒ The restart behaviour of the drive after the STO/SS1 stop function has been
executed must be parameterised to "Acknowledged restart".
ƒ The control of the SD−Out1 output via a possibly parameterised safety bus must be
inhibited.
ƒ The SS1 mode (C15306) must be set to "STO after stopping time".
ƒ The plausibility check rejects other settings until they are parameterised correctly.
