Define the send data from node 3 (drive object 3). Status word ZSW1, speed and torque
actual values should be sent from drive object 3:
1. Place parameter r0899 in send parameter p2051[0]. p2051[0] is written to the send slot
2. Because parameter r0021 is 32 bits long, place r0021 in send parameter p2061[1].
3. Parameter r0031 is also 32 bits long. Therefore, place r0079 in send parameter p2061[3].
4. The remaining slots remain empty.
