9.3 Operation
9.3.1 OperatingSteps
1) Check whether the computer and the inverter are connected correctly.
2) Turn ON the inverter. But, do not connect the load until stable communication between the computer and the
inverter is verified. Start the operating program for the inverter from the computer.
3) Operate the inverter using the operating program for the inverter.
4) Refer to “9.6 Troubleshooting” if the communication is not operating normally.
5) Turn the inverter J3 switch ON to connect the terminating resistor for the end of network.
* Connect to C+,C-,CM terminal on the control terminal. Pay attention to polarity(+, -).
* Maximum number of connected drives is 31.
