    PROGRAMMING EXAMPLES 8.10 Instructions (1) Programming instructions 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.
  • Page 89 PROGRAMMING EXAMPLES 4) If the programmable controller (master station) is reset during CC-Link operation or if the programmable controller is powered off, data communication stops and the inverter is brought to a fault "E.OP1". To reset the programmable controller (master station), switch the operation mode to the External operation once, then reset the programmable controller.

    HOW TO CHECK FOR ERROR USING THE LEDS When one inverter is connected The following diagram shows the system configuration with one inverter. The diagram indicates how the cause of the fault can be checked with the LED status of the inverter communication option (FR-A7NC). (In this example, assume SW, M/S, and PRM LEDs of the master module are OFF (master module is in normal operation).) Power...
