Fig. 81: OMS funcon
Special operaon (OMS) provides for overwring a normal stop STO, SS1 and SS2 by acvang
the enable switch (ES), see Enable S
witch (ES) funcon. ^ 437
A detected error in special operaon acvates the stop funcon that is correspondingly para-
meterised there (Safe Torque O (STO), Safe Stop 1 (SS1) or Safe Stop 2 (SS2)). The stop func-
on can be parameterised in special operaon as stop funcon.
If a request for special operaon is pending ("OMS acvaon"), the stop funcon that is para-
meterised for special operaon in 0x28A9:0010x28A9:001 (Safe Torque O (STO), Safe Stop 1
(SS1) or Safe Stop 2 (SS2)) is started.
Via Sa
fely Limited Increment (SLI), the moon funcon (SLS or retracng) parameterised for
special operaon in 0x28A9:002 0x28A9:002 can be executed.
Furthermore, 0x28CA:0030x28CA:003 can be used to switch on the monitoring funcon
(Safely Limited Increment (SLI)) for the moon funcon parameterised.
The seng "0" deacvates the SLI monitoring funcon.
Acvaon of special operaon
By means of the "Operaon mode selector" funcon, special operaon is acvated by an "ON
state" on a safe input. The funcon Enable Switch (ES) must have been assigned to the corre-
sponding input by parameterisaon.
Only if no safe input is ulised, the funcon can be acvated via the safety bus.
Via the sa
fety bus, a data telegram with a corresponding content is sent to the
inverter, see safety bus .
Deacvaon of special operaon
•
A chang
eover from special
operaon to normal operaon can only be eected when the
drive is at a standsll, see Safe Torque O (STO), Safe Stop 1 (SS1) or Safe Stop 2 (SS2) .
•
In the case of a restart, the restart (AIS) must be acknowledged via the terminals or safety
bus.
•
An automac restart is not permissible.
-
If "Automac restart" is parameterised, this has to be prevented by special measures,
e.g. programming in the master control.
