How to configure SARn
To configure the SARn (n = 0…1), set the FSO parameters listed below to appropriate
values using the Drive composer pro PC tool. See parameter groups
Safety on
page 402 and SARx on page 430 . See also section Ramp monitoring on page 57 .
Example: The figure below shows an example of a SAR1 monitoring set-up:
• SAR1
• ramp time from Scaling speed to zero: 1000 ms
( 200.112 SAR1 ramp time to zero = 1000 ms )
• Scaling speed: 1500 rpm ( 200.202 SAR speed scaling = 1500 rpm )
• initial range for monitoring: 100 ms ( SARx.02 SAR initial allowed range = 100 ms )
• minimum allowed ramp time: 500 ms
( SARx.21 SAR1 min ramp time to zero = 500 ms )
• maximum allowed ramp time: 1000 ms
( SARx.12 SAR1 max ramp time to zero = 1500 ms ).
Note: If you use SAR1 in several safety functions at the same time, tune it according
to the function which requires the tightest monitoring range.
SARx.21 = 500 ms
SARx.22 = 1500 ms
200.112 = 1000 ms
200.202
= 1500 rpm
