After the N10 file is set, B3:0/0 can be set high to send the explicit message to the scanner card. After bit I:3/15 is set by the PLC, the message can be viewed by setting B3:0/2 high which copies the M1: file to the N11: file.
The response from the drive should resemble the following.

The following table reflects the results of the Index 0 Velocity example. Note that the Low Data Word is 1000 (0x3E8), the velocity requested.
