< Write command mode (Mode 3) >
When the instruction input comes ON with the operand B+1 is 3, the Write command mode (mode 3) is selected. In this mode, the
Repeat
Sends the specified command with command data to #n Inverter
Checks the acknowledge
The target Inverter number #n is specified by the operand B.
The scan execution status and the Inverter communication status are stored in the operand B+2 to B+7.
The command code and the command data setting registers are indirectly specified by the operand A and A+1.
When the instruction input is reset to OFF, the operation is stopped after receiving the response from the Inverter.

When the data for each operand are set as above, the following operation condition is specified.
•RW200=5 ⇒ The target Inverter number is 5. Therefore
•D1000=4 & D1001=3010 ⇒ D3010 is specified as the command code setting register and D3011 is specified as the command data setting register.

Example operation:
For example, to write the acceleration time parameter (10 seconds) to the #5 Inverter, set the command code H0009 into D3010 and the value 100 into D3011.
For the command code and the command data format, refer to your Inverter manual.
