motor drives the bag gathering belts and it does not have a home position). While the
Servo Tyer is homing, several lines of information are written to the screen about the
progress of the homing sequence. When the Servo Tyer successfully completes the
homing sequence, the following prompt will appear on the screen.
MOTOR 1>
This indicates that the Servo Tyer is ready to receive commands and that any commands,
which are motor-control commands, will be applied to Motor 1, the motor that drives the
needle.
If, for any reason, the Servo Tyer does not successfully complete the homing sequence,
this will be indicated on the screen. In that case, the MOTOR1> prompt will not appear
and the controller will drop out power to all servo motors. The last two lines on the screen
will then be.
Interlock open.
Waiting for reset.
At this point, you will not be able to type commands. Based upon the information printed
