6.10. Instructions

1.Programming instructions

1.1 Since the buffer memory data of the master station is kept transferred (refreshed) to/from the inverters, the TO instruction need not be executed every scan in

response

to data write or read requests.

The execution of the TO instruction every scan does not pose any problem.

1.2If the FROM/TO instruction is executed frequently, data may not be written reliably. When transferring data between the inverter and sequence program via the buffer memory, perform the handshake to confirm that data has been written without error.

2.Operating and handling instructions

2.1Command only from the programmable controller can be accepted during operation from CC-Link communication.

The run command from external and parameter unit is ignored.

2.2If the station number of two or more inverters is the same, wrong data will be transferred and normal communication cannot be made.

2.3If a network error (controller fault , an open CC-LINK dedicated cable, etc) continues past the time set in c100 during CC-Link operation, it is recognized as a communication error and the operation of the inverter follows the setting of c101.

2.4When the programable controller (master) is reset or the power supply of the programable controller (master) is turned off during CC-Link operation, data communication stops and an inverter follows the setting of c101.
