Which products are affected?
9300EP servo positioning controller as of versions V2.5 and V6.1.
Function description
In many applications with small factors (result < 230) it was not possible to use the existing multiplication mode (selection 3) in the ARITPH blocks appropriately because owing to the ensuing division by 230 the result tended to approach zero.
The arithmetic modes for function blocks ARITPH1-6 have been expanded to include selections 13, 15, 21 and 22, as in CAM V2.x. There is also a multiplication mode without ensuing division so multiplication is now also easier to use in practice with the positioning controller.
In the previous versions it was also possible to use converter FBs as an alternative to expanding values.
Applications
Angular signal arithmetic within the scope of function block connections.
