Configuring SAR
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
