7. Instructions
< Broadcast mode (Mode 4) >
When the instruction input comes ON with the operand B+1 is 4, the Broadcast mode (mode 4)
is selected. In this mode, the T1-16S sends the user specified Write command to all the
Inverters as broadcast.
This mode is useful to send Run/Stop command to all the Inverter at the same time.
Sends the specified command with command data to all Inverters (broadcast)
Checks the acknowledge from #0 Inverter
The Inverter number specified by the operand B is ignored.
The scan execution status and the Inverter communication status are stored in the operand
B+2
to
B+7
. (only #0 Inverter responds)
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.
• D1000=4 & D1001=3020 ⇒ D3020 is specified as the command code setting register and D3021 is
specified as the command data setting register.
Data table:
Register Data contents Signal direction
D3020 Command code
D3021 Command data
→ Write
Example operation:
For example, to send the Run forward command to all the Inverters, set the command code HFA00
into D3020 and the value HC400 into D3021.
For the command code and the command data format, refer to your Inverter manual.
