How power reducing is managed by Modbus
The procedure for setting of parameters and/or execution of commands should be the following:
1. The Modbus master executes one or more write operations (with both single or multiple
registers write) on registers from 141 to 147
2. The Modbus master writes code 50 (0x0032) in register 113. When the inverter receives this
command, it makes the parameters operative.
3. The Modbus master can read register 117, checking the result.
Notice:
i.
The register 141 it’s the bitmask that enables the parameters, as reported in the table
ii. The register write on register 113 could be disabled if a local or remote operator has disabled
this function on purpose. This status can be read in bit 0 of register 8. In any case, if the write
operation is inhibited, every attempt to write register 113 will lead to a value of 0x8032 in
register 117
