Starting up the inverter with INTERBUS (MCH42A)

The WRITE service on the 'download parameter block' object starts a parameter setting
mechanism on the INTERBUS interface. This step puts all parameters specified in the
user data area of the object into the DPRAM and therefore sets the parameters of the
inverter. The write service is terminated with a positive write response once the download parameter block has been processed successfully, i.e. all parameters transmitted
by the INTERBUS interface module have been written. A negative write response is returned in case of an error. The return code contains more detailed information about the
type of error as well as the number of the parameter (no. 1...38) where the error occurred
(see example).
Example: Write error response for an error when writing the 11th parameter:
Error class: 8 Other
Error code: 0 Other
Additional code high: 11dec Error when writing parameter 11
Additional code low: 15hex Value too large
Note the following points when using the download parameter block:
'Last PCP index'
object
•
Do not perform a factory setting within the download parameter block!
•
All parameters written after the parameter lock has been activated will be rejected.
This object is 4 bytes long and, when read access is made, returns the numerical value
of the last index which can be addressed directly using the PCP services. PCP accesses
to indices greater than this numerical value must be made using the 'MOVILINK® parameter channel acyclical' object.
