A-1-3 NQ to OMRON Memobus inverter
To perform a successful communication between NQ-Series combined with OMRON Memobus inverter
proceed as follows. The example shown is applicable for V1000. The addresses and parameter settings can
vary depending on the choice of the Memobus inverter (not V1000).
1 Create a new project in NQ-Designer.
2 Right-click the Nodes folder and click Add...
3 Set all data as shown in the screenshot.
4 Create a tag with address HR401061
5 Add a display data numeric object with tag address HR401061 on screen1
6 Download the application and firmware to the NQ-Series.
7 Press down button on the inverter until PAr is shown on the inverter’s display.
8 Press enter.
9 Set the following parameters:
• B1-01=2
• H5-01 = 1 (node 1)
• H5-02 = 3 (9600 bps)
• H5-03 = 1 (even parity)
• Stop bit and Data Length are fixed as 1 and 8 respectively (refer to manual).
• H5-07 = 1 (RS-422 connection).
10 Switch off the inverter.
11 Create a cable. Refer to A-2-4 NQ to inverter (V1000, RS-422 connection)
.
12 Connect the cable to the NQ-Series and inverter.
13 Switch on the inverter.
