How to configure SS1 with speed limit activated SBC
Note
: If you configure the SS1 with speed limit activated SBC function, this activates
the same function in the SSE function (see section
How to configure SSE with speed
). This does not activate the SBC in the STO
function. If necessary, configure the SBC also in the STO function (see section
). See also the note on page
Example 1:
The figure below shows an example of the SS1-t function with speed
limit activated SBC set-up:
• SS1 function activated (
Version 1)
• SS1 with time monitored ramp (
=
SS1-t
)
• SAR1 emergency ramp (
, always with the SS1
function - see section
on page
• delay for STO activation after SS1 request: 2000 ms
2000 ms
)
• automatic acknowledgement (
Automatic
)
• redundant emergency stop button connected to input
DI X113:1 & X114:1
)
• single output connected (
=
DO X114:9
)
• brake connected to redundant output, diagnostic pulses activated
=
DO X113:7 & X114:7
and
=
On
),
= DO X113:7 & X114:7)
• speed limit activated brake in use, speed below which the brake and STO are
activated: 180.0 rpm (
=
180 rpm
)
• delay for activating STO after brake is zero (STO and SBC are activated at the
same time) (
0 ms
)
• delay for activating the brake and STO after the SBC speed limit has been
reached: 0 ms (
SS1-r ramp zero speed delay for STO
=
0 ms
)
• when no encoder is in use: delay for defining the safety function as completed,
that is, an estimated time in which the motor brakes to a stop from the maximum
speed: 1200 ms (
= 1200 ms)
• STO is activated if brake feedback fails (
STO
)
• brake feedback input connected to input
=
DI X113:2
)
• feedback input type NC (inverted state compared with the brake relay)
=
Mechanically linked NC contacts
).
