Description of function
A Modbus TCP register comprises 16bits. The values of the converter display parameters (r
parameters) cannot always be represented with 16 bits. In these particular cases, the maximum
value that can be represented is displayed.
• Unsigned: 65535
• Signed min: -32768
• Signed max: 32767

1)
We recommend using registers 40150 … 40169. Registers 40100 … 40109 are compatible with converters that have
󹪝rmware < V6.1.
2)
"R" stands for read (with FC03), "W" for write (with FC06 or FC16) and "R/W" for read/write
