* The values are transmitted as int16 (1 word) or int32 (2 words).
With 1 decimal place: Divide value by 10.
With 3 decimal places: Divide value by 1000.
Example:
PLC Value
Compax3 value
1000
1.000
(3 decimal places)
10
1.0
(1 decimal place)
The setpoint movement speeds C & D do have the same function, they differ only
in the word width.
The same applies for the setpoint accelerations A & B
You should therefore only use one of these two values.
The meaning of position setpoint value A and the setpoint movement values C & D
change with Gearing and Velocity:
With the motion function Gearing applies:
Position setpoint value A
=
Gearing numerator
Setpoint movement speeds C
& D
=
Gearing denominator
With the motion function Velocity applies:
Position setpoint value A
=
Speed
