Additional comments regarding this Chapter:
• A request (SDO request) or a response (SDO Response) always refers to one
parameter value.
• The slave only sends the response if data is available in the MICROMASTER
420/430/440. For specific objects, the appropriate BICO connections must first
be generated. This takes approximately 50 ms under normal operating
conditions.
If the inverter cannot respond to the task that was issued, then it sends an abort
telegram.
• The master may only issue a new SDO request if the response to the previous
request was received.
