Description of the Safety Module (SAF-001)
m The module SAF-001-001-001 carries out the safety function "Safe Stop 1 (SS1)" (safe
stop 1 including the time control according to EN 61800-5-2), only.
m The SS1 time of the Safety Module SAF-001-001-001 is a fixed amount of 200 ms and
cannot be parameterized.
m The tolerance of the SS1 time of the SAF-001-001-001 module is -6 ms to 1 ms due to
component tolerances and tolerances in the STO reaction time. Therefore the reaction
time is 194 ms to 201 ms until the change of the input states to < 5 V.
m Once the fixed SS1 time of 200 ms has passed the drive is switched off by a safe pulse
inhibit. The module returns to the STO state (safe torque off) after this.
m The safety function SS1 corresponds to Stop Category 1 of EN 60204-1.
m The start of activation can be reported to the controller in order to initiate a steep
braking ramp of the drive or to send the information of the coming STO to a fieldbus
master (refer to the following information):

The SS1-signaling can be evaluated via bit 1 from the controller FW V01.15 in the
parameter 108.5 (status word 2 of the drive manager).
As soon as the bit is set the SS1-time begins to run.
This bit information can be used to enable a braking procedure at the ramp in the
controller (SS1-stop, stop at the current limit) or to map to a fieldbus parameter in order
to send the information to a higher-level fieldbus master (bit 1 = 0: not activated; bit 1 = 1:
SS1-time is running).
For the required settings of a braking procedure in the controller refer to the current
parameter manual b maXX BM5000 ("SS1" stop, "SS1 stop time" and error reaction).
Besides the error reaction "SS1 stop" another available error reaction can be
parameterized as well (such as "stop at the current limit").
The module SAF-001-001-001 is also displayed in parameter 200.1 (SAF module
version) from the controller FW V01.15 (value 28):
