Modbus Register Table

Please refer to table 5-2 and table 5-3 for the Modbus Input Registers (3xxxx) and Modbus
Holding Registers (4xxxx). Settings written to the Modbus holding registers are all volatile for
ACS-20B(W)-MRTU. The values will go back to the default or previous ones after power cycling.
The settings can be kept (non-volatile) by the FC100 commands in section 5.2.

5.1.1 Modbus Input Registers

The Modbus Input Registers are listed in Table 5-2. They are read-only registers.
