5.1.5. Block Write command (10H)
Select data, which is desired to be written in block communications, in Block Communication Write
Data 1 and 2 Parameters (f870, f871). This parameter becomes effective when the system
is reset, such as when power is turned off. When the setting is completed, turn off and then on the
power.
No. Block write data For data details, see:
0 No selection -
1 Communication command 1 (FA00)
2 Communication command 2 (FA20)
3 Frequency command value (FA01)
4 Output data on the terminal board (FA50)
5 FM analog output (FA51)
6 Motor speed command (FA13)
