User manual OMRON MX2 DEVICENET OPTION BOARD

[. . . ] I112E-EN-01 MX2 DeviceNet Option Board Born to drive machines Model: 3G3AX-MX2-DRT-E USER'S MANUAL Notice: OMRON products are manufactured for use according to proper procedures by a qualified operator and only for the purposes described in this manual. The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. OMRON Product References All OMRON products are capitalized in this manual. [. . . ] 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. Not checking the cause may result in unexpected operation. 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. Refer to the DeviceNet Master Units Operation manual (Cat. 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].
