second and third words contain the data for the Set Position command that is a position. The

second word, word 1, is the least significant word of the position and the third word, word 2, is

the most significant word.

Example:

To set a position of 3,400,250, first convert the value to hexadecimal. 3,400,250 decimal equals

0033E23A hexadecimal. For this value, 0033 is the most significant word and E23A is the least

significant word. The data to be sent to the DSM314 would be:

Word 2 Word 1 Word 0 Command

0033 E23A 0023 Set Position 3,400,250

Setting up word 0 as a hexadecimal word and words 1 and 2 as a double integer in a VersaPro

Reference View Table Display will simplify immediate command entry.

The data limit values MaxPosnUu, MaxVelUu and MaxAccUu are computed as shown below:

Formulas for Computing Data Limit Variables

Position Limit MaxPosnUu Velocity Limit MaxVelUu Acceleration Limit MaxAccUu

If uu:cts >= 1:1

MaxPosnUu = 536,870,912

Else (uu:cts < 1:1)

MaxPosnUu = 536,870,912 * uu/cts

MaxVelUu = 1,000,000* uu/cts If uu:cts >= 1:1

MaxAccUu = 1,073,741,823

Else (uu:cts < 1:1)

MaxAccUu = 1,073,741,823* uu/cts
