The safety function is activated via
 1/0 pulse edge at the input "SS1 Activate"
or
 1/0 pulse edge at the input "SS1 SIL3/Reset"
 Internal error
Signal status of the inputs "SS1 Activate" and "SS1 SIL3/Reset"
 The STO delay time starts when one of the two inputs "SS1 Activate"
or "SS1 SIL3/Reset" is set to "0". The safety function "STO" is acti-
vated once the STO delay time has elapsed.
 The safety function "STO" is activated immediately if the second input
is also set to "0".
 The safety function "STO" is always activated when both the inputs
"SS1 Activate" and "SS1 SIL3/Reset" are set to "0".
Sicherheitsfunktion_SS1_SS2_Ausloesung  The method by which the servo amplifier receives the command for
controlled braking of the motor is defined in the Configurator:
– Drive-activated: After the safety function is triggered, the safety
card issues a command to the servo amplifier for controlled braking
of the motor. The braking ramp is configured in the Configurator.
– Controller-activated: After the safety function is triggered, the
control system issues a command to the servo amplifier for con-
trolled braking of the motor. The braking ramp must only be con-
figured in the Configurator if monitoring of the braking ramp is also
activate there.
