QUERY command
Whenever the needle, twister hook or holder shear motors are commanded to make a
move, information is stored in a QUERY buffer about all the servo motor positions,
speeds, and motor commands during the move. This data can be displayed by using the
QUERY command.
The information displayed by this command can be helpful in diagnosing certain complex
problems. However, analyzing this data is very difficult for anyone not familiar with the
inner workings of the Servo Tyer. It is easy to draw incorrect conclusions from the data.
Therefore, the most likely customer use for this command is to display data, which can
be captured into a text file. Then the customer would normally print the file and send the
data to Burford
®
Corp. for analysis. Contact the Service Manager at Burford
®
Corp. if you
wish to do this.
The information in the QUERY buffer is automatically overwritten when the next move
occurs, so this buffer always contains information about the most recent move. When the
MOT>1 prompt is displayed, the data displayed is for the needle motor only. When the
MOT>2 prompt is displayed, the data displayed is for the twister hook motor only. When
the MOT>3 prompt is displayed, the data displayed is for the holder shear motor only.
When the MOT>4 prompt is displayed, the data displayed is for the gathering belts motor
only. To change to a different motor, say the twister hook motor, simply type MOT=2. The
MOT 2> prompt will then be displayed.
