Safety Function STO
3.6.4 Wiring SS1
At tripping SS1 (Safe Stop 1) the drive is disconnected from supply only when it has reached
a standstill [IEC 61800-5-2]. The stop mode is not directly requested, but the maximum time
until reaching the standstill is estimated. This period is loaded in a safe time relay, which dis
-
connects the drive finally from supply.

By activation of the emergency stop unit the drive is stopped with a deceleration ramp via
input X2A.12 (I3).
Simultaneously the ramp-down time of the safe period starts in the safety module. After
ramp-down time of the safe period the control signals STO1 and STO2 (X2B.1 and 5) are
switched off and thus the energy supply of the drive is disconnected.
The following adjustments must be done in COMBIVERT for the function „drive stop“:
Parameter
Adjustment
Pn.03 „Reaction to error prg. input“
1: Quick stopping; modulation off; no auto
-
matic restart
Function: If the selected input becomes active, the drive decelerates with the quick stopping
function and changes then into status 31 „error! External input“.
