[. . . ] Set parameter P033=6 to assign Torque command input selection to Option Board. Restart the Inverter or reset the Option Board for the new settings to take effect. The Inverter will only allow setting of torque related registers if it is configured to operate with CT rating in Std. Your input and output words should now have the following layout:

Set the maximum allowable output frequency in torque mode by configuring P039 and P040 for the forward- and reverse run directions. Set the Rotation Speed Reference (see Appendix B Assembly Specification on page 41) of the Inverter in the 2nd I/O output word to 10. 00 Hz. Set the Torque Reference of the Inverter in the 3rd I/O output word to 20%. Override the input terminal 3 (CI3) to enable torque command input.
Step 8 Step 9 Step 10
Faults and Trips
The motor either accelerates or decelerates depending on the load. Step 11 To change the torque command direction, clear the FWD bit and set the REV bit. Note As an alternative for the overriding of input terminal 3 from the network at step 10, also the physical input terminal can be used.
Faults and Trips
You may want to trip the Inverter from your PLC program. Not all assemblies support setting the external trip by using a bit in IO Data. Basically there are two options: · Select an assembly which support this trip set in the output data. · Using explicit message to set the Force Fault/Trip attribute in the Control Supervisor Object (Class 29 Hex, Instance 01 Hex, Attribute 11 Hex). The two Extended Control IO assemblies (Output 101, Input 151) contains the FFL (Force Fault/Trip) bit and can be used for this feature. Step 1 Step 2 Follow the instructions sections 3-1 Installation of EDS files and 3-2 Configuring the Option Board to configure the assemblies. Set bit 8 (FFL) of the first word of the output data to trip the Inverter. The alternative is to use the explicit message mechanism to generate the external trip. Please refer to Appendix E CompoNet Explicit Messages example 3 for a description how to do this.
Clearing a Trip
When the inverter trips due to a fault condition first analyse the trip cause as explained in section 5-1 Troubleshooting Using the LED Indicators on page 31 or section 5-3 Maintenance and Inspection on page 36. Notice that the FLT bit is set (present in all output assemblies) when the Inverter trips.
In the event the Inverter is in a Trip state, be sure to investigate the cause of this Trip state thoroughly before clearing the Trip. Please clear the FWD and REV bits in your PLC program when a rising edge is detected on FLT. Always clear the run bits FWD and REV in your PLC program on the rising edge of the FLT bit. [. . . ] Set the following register values: · P160 = 1F01h: This gives you control over Modbus Coils 0000h through 000Fh using the first output word. These coils implement all the important control functions of the MX2-A@ Inverter. · P161 = 0001h and P162 = 0002h: This gives you control over the frequency reference using output words 2 and 3. · P170 = 1E01h: This allows you to monitor Modbus Coils 0010h through 001Fh as the first input word.
