Programmable SyncPos motion controller

MG.10.J8.02 – VLT is a registered Danfoss trade mark

The following chapters describe how to program using SyncPos. Beginners should

read the basic explanations on the programming language SyncPos, i.e. program

layout, command structure, interrupt, elements of the programming language,

arithmetic and user unit. Experienced users should inform themselves about the

SyncPos-specific basic principles, e.g. user unit or parameters.

All commands are described in the Software Reference, first in a general over-

view and then alphabetically ordered, in detail and complemented with short

examples. You can reconstruct as many as 50 programs with assistance of the

information in the example programs in the Online-Help.

And in chapter Parameter Reference all the parameters are described, first in

general and then in detail.
