[. . . ] The PROFIdrive device profile does not provide a standard interface to achieve this, but you can use the Modbus coil number 0003h to generate an external trip (EXT): Step 1 Step 2 Follow the instructions in section 4-3-2 Mapping Coil Data 0 to map Coil data 0 into PZD3. Set bit 3 (EXT) of Coil data 0 which has been mapped into PZD3 to trip the Inverter.

Refer to section 5-1 Troubleshooting using the LED indicators or section 5-2 Troubleshooting Using PROFIBUS Diagnostics. You must always immediately clear the Run bit in your PLC program when a rising edge is detected on Flt. If the Run bit is set when the trip condition is cleared, the Inverter will immediately start running!Set the Rst bit in the STW register to clear the trip.

You can use any of the following tasks by writing the task number to AK in the output process area. Table 38 Parameter Processing Tasks AK 0 1 2 3 6 7 8 9 Task description Clear the input message area Read parameter value Change WORD parameter value Change DWORD parameter value Read element value in array Change WORD element value in array Change DWORD element value in array Read array size Some parameters contain arrays and have to be accessed using array tasks (Tasks 6, 7 and 8). When the Option Board completes the task, a task response is written to AK in the input process area. The size of the parameter is given by the task response number. Table 39 Parameter Processing Task Responses AK 0 1 2 4 5 6 7 8 Task description No response Task success (WORD parameter) Task success (DWORD parameter) Task success (WORD element) Task success (DWORD element) Task success (Array size) Task failed (Parameter) Task failed (Element) If you executed an array tasks, you will accordingly receive an array task response ID (Task response 4, 5 or 8). When a read task succeeds, the Option Board also writes the value to PWE in the input process area. When you start a write task, you must also write the new parameter value to PWE in the output process area. 27 Accessing Parameters Section 4-5 When a task fails, the Option Board writes a 7 or 8 (Task failed) to AK and an error number to PWE in the input process area. All error numbers are listed in APPENDIX G PROFIdrive Error Numbers. Note If you want to use a DINT to write or read PWE, you will have to swap the high- and low-word in your PLC program (For double-words, an OMRON PLCs does not use the same word-order convention than PROFIBUS). The parameter processing message area is only available when using the PPO Type 1, PPO Type 2 or PPO Type 5 module. To access parameters when using the PPO Type 3 or PPO Type 4 module, make use of the PROFIdrive DP-V1 parameter channel (Refer to section 4-5-2 PROFIdrive DP-V1 Parameter Channel). Set AK to the desired task. Note Tip The parameter processing message mailbox is triggered by a change in the parameter processing output area. By first setting AK=0, you avoid unintentionally starting a write task when you start changing PNU, IND and PWE. 4-5-1-1 Accessing Option Board Parameters Option Board parameters are addressed by writing the parameter number to PNU (Refer to APPENDIX F Option Board Parameters for a list of the available Option Board parameters). If you are addressing an element in an Option Board parameter array, you must also write the element index to IND. When writing an Option Board parameter, the task number specifies the write size. The following example demonstrates how to use the parameter process message area to access Option Board parameters: Step 1 Reading an Option Board Parameter: To read Option Board parameter 965 (Unit profile code): First set PNU and then AK as illustrated below. The Option Board will respond with the illustrated values.

After the PROFIBUS master has re-connected, the Option Board tries to execute the task a second time. [. . . ] · 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. These coils implement the most important status information of the MX2-A@ Inverter. The Modbus coil definitions for the MX2-A@ Inverter are listed in section B-4-1 of the MX2 user's manual. [. . . ]
