Connecting NQ Terminal To MX2 Inverter
Below steps describe the connection of a NQ HMI terminal to a MX2 inverter.
If NQ needs to be terminated, be aware to use a 200 ohm resistor to match the MX2 internal termination resistor.
NQ designer setup
MX2 parameter settings
Open manual I114-EN-01 and go to section B2. Here are the parameters that need to be set to make sure MX2 is able to communicate. Match the parameters of MX2 inverter to the settings in the NQ terminal. After changing the settings recycle power of the MX2. If parameters are set properly communication between NQ and MX2 is established. When adding more tags in the NQ please note that addressing in MX2 is in HEX format and in NQ INT format. (example (000AH (MX2)= 10 (NQ)
Attached MX2.nqp file shows example how to connect to MX2. Set following settings in MX2 and recycle power:
