Mitsubishi Electric MELIPM Series Instruction Manual page 69

The above format assumes that the data code has two characters.
The number of characters in the data code changes with the
communication data.
When using the computer sending data to set the "waiting time",
insert the "waiting time" data (one character) in the position next to
the instruction code. Set it within the range 0 to 150ms in 10ms
increments. (Example; 1: 10ms, 2: 20ms)

In this case, set 9999 in Pr. 123.

MEMO
The CR (carriage return) and LF (line feed) codes at the format end
are automatically set by the computer when data is sent from the
computer to the drive unit.
In this case, the sending data from the drive unit must also be set to
match the computer data.
Select whether the CR and LF are used or not by setting the Pr.
124 value.
Expression for calculating the communication data sending time
Data send time (s) = total number of bits in one character × total
The total number of bits in one character is equal to the total number
of following bits.
Start bit:
