NORD USS and Modbus RTU Manual
48 Subject to technical amendments BU 0050 GB-3111
1.6.5 Reading the acceleration time parameter
The acceleration time parameter (USS No. = 102
dec
/ 66
hex
) in parameter set 2 of a frequency inverter with the
USS address 3, is to be read out. No process data is transferred.
Procedure:
 Set address (Address 03)
 Generate parameter label (PKE 10 66)
 Select parameter set 2 (IND = 01)
 Send telegram
 Check response telegram (PWE = 3E8)

The value sent in PWE2 is C8
HEX
corresponding to 1000
DEC
, with a resolution of 0.01 seconds, this
corresponds to an acceleration time of 1000 * 0.01 = 10 seconds
 10 / 0.01 = 1000 (3E8
hex
)
