user can also set the reaction type and the delay for activating the STO indication
after the modulation loss.
For this procedure to work, at least the auxiliary power (24 V DC) to the control unit
and the FSO module must be on. For more information, see section SLS reaction
when modulation is lost during deceleration ramp, with ramp monitoring on page 147.
SLS with speed below monitored speed
This applies to both time and ramp monitoring.
A SLS trip limit positive (parameter SLSx.14, SLSx.23, SLSx.33 or SLSx.43)
B SLS limit positive (parameter 200.23, 200.33, 200.43 or 200.53)
