S_Cycle_Count: Counter For The Safety Cycle; S_Xist16: Current Actual Position Value (16 Bits); S_Xist32: Current Actual Position Value (32 Bits) - Siemens SINUMERIK MC Commissioning Manual

● Value range 1 ... 32767; 32767 ≙ 100%
● Must only be evaluated if SLS 1 active and p9501.24 = 1.
10.5.2.8

S_CYCLE_COUNT: Counter for the safety cycle

S_CYCLE_COUNT
● PZD4 in telegrams 901 and 902, input signals
● Counter for the safety cycle
● Value range -32768 ... +32767
● May only be evaluated if the transfer of safe position values is active (p9501.25 = 1) and the
position value is valid (r9722.22 = r9722.23 = 1).
10.5.2.9

S_XIST16: Current actual position value (16 bits)

S_XIST16
● PZD5 in telegram 901, input signals
● Current actual position value (16 bits)
● Value range ±32767
● Scaling using p9574
Note
Scaling
It is not permissible that the position value transferred in S_XIST16 exceeds the value range
that can be represented. This is the reason that the safe position value of the drive (r9713[0])
can be allocated a scaling factor. The position value is divided by this factor before transfer.
As a consequence, a wider value range can be transferred with a reduced accuracy.
Example: For a position of -29.999 mm signaled in r9708[0] and r9708[1] and a scaling
factor of p9x74 = 1000, a numerical value of -29 is signaled to the controller.
● May only be evaluated if the transfer of safe position values is active (p9501.25 = 1) and the
position value is valid (r9722.22 = r9722.23 = 1).
10.5.2.10

S_XIST32: Current actual position value (32 bits)

S_XIST32
● PZD5 and PZD6 in telegram 902, input signals
● Current actual position value (32 bits)
● Value range ±737280000
