PARAMETER
(2) Pulse train form selection (PP, NP signal) [Pr. 428]
Command pulse can be changed according to the
positioning unit as in the table below.
(3) Interface of the positioning unit and inverter
When running the inverter by each positioning unit,
interface of the positioning command pulse train
need to be matched.
