should be ensured between two messages addressed to the same inver-
ter (refer to section 8.18.6.).
8.19.3.6 Message
Sequence
8.19.3.7 Variable Code
The field designated with CODE determines the parameter address and
the basic variables formed by 5 digits (ASCII characters) as follows:
8.19.4 Message Examples

Writing Message:
no answer: with wrong message structure, control characters
received incorrectly or wrong inverter address;
NAK: CODE corresponding to a non existing variable, wrong BCC
(checksum byte), only reading variable, VAL out of the allowed
range for the respective variable, operation parameter out of the alteration
mode;
ACK: with valid message;
The master should maintain, between two variable transmissions to the
same inverter, a waiting time that is compatible with the used inverter.
