Slave User Parameter - Mitsubishi Electric FR-E5NP Instruction Manual

5.2 Slave User Parameter

By changing the slave user parameter value, you can use the byte swapping function (byte inversion
function).
Setting "1" at Address 1H (Bit 0) makes the byte swapping function valid.
Since "-" is an unused bit, set "0".
