Data Description
8.2 Parameters for SINAMICS S120
p9526 SI motion encoder assignment second channel
Sets the number of the encoder that is used in the second channel (control,
Motor Module) for safe motion monitoring functions.
Note:
For safety–related motion monitoring functions the redundant safety position
actual value sensing must be activated in the appropriate encoder data set
(p0430.19 = 1).
For p9526 = 1, the encoder for the closed–loop speed control is used for the
second channel of the motion monitoring functions (1–encoder system).
Unit: Default value:
– 1
p9530 SI motion standstill tolerance (Control Unit)
Sets the tolerance for the "safe operating stop" function (SOS).
Unit: 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 issues the fault C01707 ("SI motion: Tolerance for safe operating
stop exceeded") and activates the stop response STOP B/A.
p9531[0...3] SI motion SLS (SG) limits (Control Unit)
Sets the limit values for the "safely limited speed" function (SLS).
Index:
[0] = limit value SLS1
[1] = limit value SLS2
[2] = limit value SLS3
[3] = limit value SLS4
Unit: Default value:
mm/min 2000
If one of the monitoring functions SG1, SG2, SG3 or SG4 is selected then the
actual velocity exceeds the limit value set in this parameter, the drive issues fault
C01714 ("SI motion: Safely reduced speed exceeded") and activates the stop
response parameterized in p9561 or p9563.
