Starting up the inverter with INTERBUS (MCH42A)

Writing IPOS
plus®
variables /
parameters via
download
parameter block
MOVIDRIVE
®
inverters enable you to use the download parameter block to write
several IPOS
plus®
variables and/or parameters at the same time with a single PCP
service.
The download parameter block is always 230 bytes long. A maximum of 42 drive
parameters or IPOS
plus®
variables can be written in one block.
Example
Three values of the inverter are to be written with one "Write_Request":
You will receive the "Write_Confirmation" after this service has been sent. Once again,
you can use the return codes for evaluating a negative message. The individual
parameters of the download parameter block in the inverter are written one after the
other. This means if there is a negative "Write_Confirmation" in the high part of the
Additional_Code, the parameter number at which the error occurred is entered.
