6.2.11.5 Safety limits
The inverter has funcons for
supporng the safety technology. Depending on the required
safety funcon, automac intervenon in the setpoint value generaon of the axis takes
place.
When safety technology is used in coupled axes, it might be required that a requested safety
funcon does not respond within the single axes but that the responses are recognised cen-
trally. This recognion can be realised via a virtual master.
The following safety funcons can be limited or deacvated:
4Safe Torque O (STO) ^ 398
4Sa
fe Stop 1 (SS1) ^ 403
4Safe Stop 2 (SS2) ^ 406
4Sa
fely-Limited Speed (SLS) 1 ... 4 ^ 412
4Safe Direcon (SDI) posive/negave ^ 420
The requested safety funcon is displayed in the Status limiter parameter. 40x500A:163
The safety funcon can be deacvated in the Deacvate safety funcons parameter.
40x500A:162
In the case of
deacvated funcons, the axis does not inuence the setpoint value.

Aer the standsll is reached, the drive is disabled. The drive is braked to standsll with the parameters Quick stop applica-
on - deceleraon und Quick stop applicaon - jerk.
Aer standsll has been reached, the posion control of the drive
remains acve.
Safely limited speed (SLS) 1 ... 4
The following parameters limit the speeds and set delay mes of the axis:
Speed Deceleraon me
Limited speed 1 0x500A:150 0x500A:151
Limited speed 2 0x500A:152 0x500A:153
Limited speed 3 0x500A:154 0x500A:155
Limited speed 4 0x500A:156 0x500A:157
•
If the curr
ent setpoint speed exceeds the value set for the requested limited speed, the
setpoint speed is reduced to the requested limited speed within the parametrised delay
me.
•
If several limited speeds are requested at the same me, the lowest speed is reduced with
the highes
t deceleraon.
