Mapping The Holding Registers To Drive Parameters - Danfoss VLT DriveMotor FCP 106 Programming Manual

RS-485 Installation and Set...
The PCD read list is data send from the to the controller
like Status word, Main Actual Value and application
dependent data like Running Hours, Motor current and
Alarm word.
NOTICE

32 bit parameters must be mapped inside the 32 bit
boundaries, (PCD2 & PCD3 or PCD4 & PCD5 etc.) where
the parameter number is mapped twice to8-42 PCD Write
Configuration or 8-43 PCD Read Configuration.
