Speed zero monitoring can be activated for each drive that is connected to the
gateway and signals when a drive is at standstill. Safety monitoring prevents an unin‐
tentional start of the drive from standstill.
4.7.1 Configuration of OSSD Monitoring
In order to reach the functional safety of SIL3 (Safety Integrity Level 3 according to DIN
EN 61800-5-2:2014-06) both channels (
OSSD_SAFEA and OSSD_SAFEB as well as
OSSD_ZEROA and OSSD_ZEROB) must be connected to a safety PLC. A control via
only one channel is not sufficient for SIL3.

Fig. 4: Speed zero connection with OSSD (SIL3)
To obtain the safety level SIL3 the safety PLC as well as the drive have to be
certificated safety devices of at least level SIL3.
You set the speed zero monitoring in the configuration mode via the 16 DIP switches at
the bottom side of the gateway. On delivery of the gateway no drive is selected for
speed zero monitoring (all DIP switches are set to zero). Configure the speed zero
monitoring for the desired drives as described in the following.
Speed zero monitoring with OSSD signals
➮ Select the drives to be monitored by means of the DIP switches. For further infor‐
mation on the drive selection refer to section 6.1.4 "Drive Selection Switches",
page 30 .
➮ Turn the operating mode selection switch MODE to '9' (configuration: speed zero
with OSSD signals).
➮ The status LEDs of the selected drives flash red at the gateway. Check the drive
selection by means of the LEDs and correct it, if required.
