The enable (EO) output is most often used to turn the motor excitation circuit ON/OFF.  The initial state of the enable outputs can be defined by setting the 4-bit EOBOOT register to the desired initial enable output value.

A jog move (J) is used to continuously move the motor without stopping. Unlike a Jog operation, a Positioning operation is a move with a specified stop point.  The stop point will be either an absolute position in relation to the 0 start point that was defined during homing, or an incremental position from the motor’s current position.

The Commander core supports the ability to change the moving speed and/or the target position on the fly.  On-the-fly speed change (SSPD) will change the speed while an axis is in motion, at any point in the motion profile.  On-the-fly target position change can be achieved using the T command, and will change the final destination of the motor while the motor is moving.

The speed range is set with the SSPDM command.  

For more information on the settings, see the following sections in the Commander manual:
