When the drive inverter is parameterized via the acyclic MOVILINK
®
parameter channel, a distinc-
tion is made between the following two operations:
1) Parameter channel executes a Write service.
2) Parameter channel executes a Read service.
1) Parameter channel executes a Write service
If a Write service is executed via the acyclic parameter channel (e.g. Write Parameter, Write Param-
eter Volatile) the inverter will return the service acknowledgement for this service after it has
executed the service. If the Write access produces a fault, the corresponding fault code is returned.
This variant has the advantage that by sending one WRITE MOVILINK
®
Parameter Channel the
Write services can be executed and the service be acknowledged by the evaluation of the FMS
confirmation (Fig. 44).

1. Initiate execution of the service coded in the parameter
channel with WRITE to the "MOVILINK Acyclic Parameter
Channel object"
The WRITE service coded in the
parameter channel is executed
and the service acknowledgement
immediately returned as the
response
