These commands behave identical to the

Open Loop

ASCII command, except that the

specified stored

profile

information is copied into the active MODE, ACCEL, DECEL

and SPEED first. Recall that the SPEED field of the profile is not used by the

Open

Loop

. Refer to that command for further details.

The format of the Command Register for the Open Loop Using Profile commands is

given below:

The data for the command

Output register

represents the requested drive in millivolts.

Example

Suppose you would like to axis 0 to go into open loop at 2000mV of drive using profile

10 and axis 1 to go into open loop at 4000mV of drive using profile 11. You would send

the commands in the following format:

SAR

CMND INDX (HEX)

4TTTTT+0 0000|XXXX|1001|1010 (0X9A)
