p9542 SI motion, actual value comparison tolerance (crosswise)
Sets the tolerance in mm or Degrees for the crosswise comparison of the ac-
tual position between the two monitoring channels
Units: Default value:
mm 0,1
See also: C01711 "SI motion: Defect in a monitoring channel".
p9544 SI motion, actual value comparison tolerance (referencing)
Sets the tolerance in mm or Degrees to check the actual values after referenc-
ing (incremental encoder) or when powering-up (absolute encoder).
Units: Default value:
mm 0,01
See also: C01711 "SI motion: Defect in a monitoring channel".
p9546 SI motion, velocity limit n
Sets the velocity limit n in mm/min or rpm to detect zero speed. When this limit
x
value is fallen below, SGA "n < n
Units: Default value:
mm/min 20
rpm
p9548 SI motion, SBR actual velocity tolerance
Sets the velocity tolerance in mm/min or rpm for the "safe braking ramp" (SBR)
Units: Default value:
mm/min 300
rpm
See also: C01706 "SI motion: Safe braking ramp exceeded".
After initiating the safe braking ramp (SBR) for the stop responses STOP B and
STOP C, the actual velocity plus the tolerance value parameterized in p9548 may
not exceed the actual velocity sensed in the last monitoring clock cycle. If p9548 >
0, then the value converted into the internal format is limited to greater than or
equal to 1.
p9549 SI motion, slip velocity tolerance
Sets the velocity tolerance in mm/min or rpm, that is used for a 2-encoder sys-
tem in a crosswise comparison between the drive and control. If the "actual
value synchronization" is not enabled (p9501 3 = 0), then the value parameter-
ized in p9542 is used as tolerance in the crosswise data comparison.
Units: Default value:
mm/min 6
rpm
