Appendix 2 Response time
The communication response time can be calculated from data communication time and inverter
processing time.
When wishing to know the communication response time, calculate using the fol-
lowing as a reference

* Number of bits = start bit + data frame length + parity bit + stop bit
* Minimum number of bits = 1 + 8 + 0 + 1 = 10 bits
* Maximum number of bits = 1 + 8 + 1 + 2 = 12 bits
