FUN 236 XFER Expanded data transfer (Inverter connection mode)
Expression
Input −[ A XFER B → C ]− Output
Function
This function is provided to control Toshiba Inverters VF-A7/G7/S9 connected on the RS-485 line.
When the RS-485 port operation mode is set to the Inverter mode (SW56 = 3), the T1-16S can
perform the following functions for up to 63 Inverters.
(1) Cyclically scans the Inverters and sends/receives the following data to/from each Inverter.
• Send to Inverter: Frequency reference write and Operation command write (Run, Stop, etc.)
• Receive from Inverter: Operating frequency monitor and Output terminal status monitor
(2) Cyclically scans the Inverters and receives the following data from each Inverter.
• Receive from Inverter: Operating frequency monitor and Output terminal status monitor
(3) Sends a specified Read command to a specified Inverter and stores the response data.
(4) Sends a specified Write command with the command data to a specified Inverter.
(5) Sends a specified Write command with the command data to all the connected inverters as
broadcast.
