SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MA_SAFE_DES_VELO_LIMIT
SG setpoint speed limiting
Min. input limit: 0
Protection level: 7/2
This is an evaluation factor to define the setpoint limit from the actual speed limit. The
active SG limit value is evaluated using this factor and is entered into the interpolator as
setpoint limit. When SBH is selected, a setpoint of 0 is entered.
When 100% is entered, the setpoint is limited to the active SG stage
When 0% is entered the setpoint speed limiting is not active.
– This MD may have to be altered several times before an optimum setting for the dy-
namic response of the drives is found. In order that this operation is not made unneces-
sarily complex, "reset" has been defined as the criterium for being effective.
– This data is not included in the crosswise data comparison with the drive.
– This data is not included in the axial checksum $MA_SAFE_ACT_CHECKSUM, as it is
a single-channel function.
Refer to Section : 11.1 "Limiting the setpoint speed"
