PS.25
The maximum prole speed is preset via PS.31 "index / speed".
The drive shall stop at the target, so the target speed must be
PS.25 = 0 for all blocks.
All other bits can remain at the factory settings for this example and are explained in the following chapters.
● Block 0 denes the start position → PS.28 = 0
● Input I3 serves as "start positioning" → PS.29 = 64: I3 (X2A.12)
● The maximum prole speed is calculated from:
PS.31 (max. speed setting %) x oP.10 (max. reference forward)
To change this analog via AN2, the following adjustments must be made:
(also see chapter 7.15.8: analog parameter setting)
An.30: Sel. REF input./AUX function = 2112 (factory setting)
An.53: Analog para. setting source = 0:AUX input (ru.53) (factory setting)
An.54: Analog para. setting destina-
tion
= 131Fh (bus address PS.31)
An.55: Analog para. setting. / offset = 0 (factory setting)
An.56: Analog para. setting max.
value
= 1000 = 100%
oP.10: max. setpoint forward = 1500 rpm (max.possible prole speed)
An.30 denes that AN2 serves as AUX input.
An.53 denes that the parameter value is preset via the AUX input.
An.54 denes the bus address of the parameter to be set by analog input (here, PS.31)
(the bus address of a parameter can be read in Combivis in, e.g., the work list).
An.56 denes the maximum value (unnormalised) for parameter PS.31. Then the normalised value for
PS.31 is calculated as follows:
100% AUX value = maximum value (An.56) x resolution of the parameter PS.31 (0.1%) =
1000 x 0.1% = 100%
The value for PS.31 corresponds to the AUX value.
Then the maximum prole speed is calculated as follows:
ru.63: Prole speed = PS.31 x oP.10 = AUX x oP.10
● block 0 → PS.23: Index / selection = 0
Position = 0 → PS.24: Index / position = 0
