Data Description
8.2 Parameters for SINAMICS S120
p9521[0...7] SI motion, gearbox, encoder/load, denominator
Sets the denominator for the gearbox between the encoder and load. The ac-
tual stage is selected using safety-relevant inputs (SGE).
Units: Default value:
– 1
Denominator of the fraction "number of encoder revolutions / number of load rev-
olutions".
There are a total of 8 values (8 indices of p9521), whereby, the actual value is se-
lected using SGEs.
p9522[0...7] SI motion, gearbox encoder/load, numerator
Sets the numerator for the gearbox between the encoder and load. The actual
stage is selected using safety-relevant inputs (SGE).
Units: Default value:
– 1
Numerator of the fraction "number of encoder revolutions / number of load rev-
olutions".
There are a total of 8 values (8 indices of p9522), whereby, the actual value is se-
lected using SGEs.
p9526 SI motion, encoder assignment control
Sets the number of the encoder that the control uses for the safety-relevant
motion monitoring functions.
Note:
If a 1 is parameterized (the control uses an encoder for the speed control), then
a single-encoder system is being used.
Units: Default value:
– 1
For safety-relevant motion monitoring functions the redundant safety position actual value sensing must be activated in
the appropriate encoder data set (p0430.19 = 1).
See also: p0187, p0188, p0189, p0430
For safety-relevant motion monitoring functions the redundant safety position ac-
tual value sensing must be activated in the appropriate encoder data set (p0430.19
= 1).
p9530 SI motion, standstill (stop) tolerance
Sets the tolerance in mm or Degrees for the function "safe operating
stop" (SBH)
Units: Default value:
mm 1
If safe operating stop (SBH) is selected, and the difference between the position
setpoint and the position actual value is greater than the tolerance set in this pa-
rameter, the drive initiates a fault F01707 ("SI motion: Tolerance for safe operating
stop exceeded") and activates the stop response STOP B/A.
