Reading the Run-Up Time Parameter
The run-up time parameter (USS no. = 102
dez
/ 66
hex
) in parameter record
2 of a frequency converter with the USIP address 3 is to be read out.
There aren't any process data transmitted.
Procedure:
•
Set address (address 03)
•
Generate parameter identification (PKE 10 66)
•
Select parameter record 2 (IND = 01)
•
Transmit telegram
•
Check response telegram (PV = 3E8)

;
with a resolution of 0.01 seconds, this equals a run-up time of 1000 * 0.01
= 10 seconds
10 / 0.01 = 1000 (03 E8
hex
)
