Operands:
S1: Data address for writing S2: Register that saves the written data
Program Example:
1. Assume that it will read the data from MODBUS address H2100, and then write to D0;
read from H2101 and write to D0.
2. When M0=ON, it will write the data in D10 to the MODBUS address H2001 of the VFD-E.
3. When M1=ON, it will write the data in H2 to the MODBUS address H2000 of the VFD-E,
i.e. start the AC motor drive.
4. When M2=ON, it will write the data in H1 to the MODBUS address H2000 of the VFD-E,
i.e. stop the AC motor drive.
5. When data is written successfully, M1017 will be ON.
6. When writing parameters, the allowable times to revise a parameter is 10
6
times. A
memory write fault may occur at EEPROM if parameters are written too often.
