Safety Function STO
3.6.4 Wiring SS1
At tripping SS1 (Safe Stop 1) the drive is only disconnected from supply 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.

When pressing the emergency stop unit the drive is stopped with a deceleration ramp via
input X2A.13 (I3).
Simultaneously the expiration of the safe time occurs in the safety module. After expiration of
the safe period the control signals STO1+ und STO2+ (X2B.1 and 5) are removed and thus
the energy supply of the drive is disconnected.
The following adjustments must be done in the drive module for the function „drive stop“:
Parameter Adjustment
pn29 „prg. error stop. mode“ (Index 0x2A1D) 1: dec. ramp -> Fault
pn48-59 (0x2A30-0x2A3C) Adjustment of the deceleration and jerk
values for the adjusted error reaction
pn30 „prog. error source“ (Index 0x2A1E) 4: I3 (here in the example)
