7. Instructions
< Read command mode (Mode 2) >
When the instruction input comes ON with the operand B+1 is 2, the Read command mode
(mode 2) is selected. In this mode, the T1-16S sends the user specified Read command to the
Inverter specified by the operand B, and repeats.
Sends the specified command to #n Inve rter
Receives the response and stores the data into the r egister
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 setting register and the response data storing register is 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.
Example
Data table designation Parameter & status RS-485 port
D1000 4 RW200 3 D1010 H0030 (f ixed)
D1001 3000 RW201 2 (mode 2) D1011 0 (fixed)
RW202 Execution stat us
RW203 Comm error code
RW204
RW205 Inverter com ms
RW206 status m ap
RW207
When the data for each operand are set as above, the following operati on condition is specified.
RW200=3 The target Invert er number is 3. Therefore T1-16S comm unicates with #3 Inverter.
D1000=4 & D1001=3000 D3000 is specified as the comm and setting register and D3001 is specified
as the response data storing register.

D3001 Response data Read
Example operation:
For example, to read the output curren t from the #3 I nverter, set the command code HFE03 into
D3000. Then the response data is stored in D3001. If the response data is 1915, it means 19.15 %.
For the command code and the data format of the response, refer to your I nverter manual.
