Be careful to select safe limits for your test setup. 24 Faults and Trips Step 7 Section 4-5 Set the Rotation Speed Reference (see APPENDIX B Assembly Specification on page 43) 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%. 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. Step 8 Step 9 Step 10 4-5 4-5-1 Faults and Trips External Trip 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 DeviceNet Explicit Messages example 3 for a description how to do this. 4-5-2 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 33 or section 5-3 Maintenance and Inspection on page 38. Notice that the FLT bit is set (present in all output assemblies) when the Inverter trips. !WARNING 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. Set the RST bit of the output assembly to clear the trip. Step 1 Step 2 25 Accessing Parameters !WARNING Section 4-6 Always clear the run bits FWD and REV in your PLC program on the rising edge of the FLT bit. Not doing so may result in the motor starting unexpectedly when the trip is cleared via DeviceNet or the , , Stop/reset" button on the Inverter 4-6 Accessing Parameters DeviceNet explicit messages sent from the Master Unit to the 3G3AX-MX2-DRT-E Unit can be used to access any parameter from the Unit or the MX2-A@ Inverter. Please refer to the APPENDIX E DeviceNet Explicit Messages on page 71 for details and examples. W380) for details on how to send the explicit messages to the 3G3AX-MX2-DRT-E. Below are examples for usage of the OMRON CJ1W-DRM21 Master Unit with the FINS Explicit Message Send command (2801). 4-6-1 Accessing General (AC Drive Profile) Objects Reading the value of MX2-A@ inverter input terminal [4].

[. . . ] 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.
