CHAPTER 7: TROUBLESHOOTING
Troubleshooting Considerations
The Servo Tyer CPU board must be working properly for it to talk to the PC. If you are
having a problem that prevents the CPU board from operating (such as a faulty power
supply or a loose power connector), you cannot communicate with the Servo Tyer
controller.
Communication with the Servo Tyer controller may be conducted while the Servo Tyer is
operating and tying packages. In fact, operation of the Servo Tyer is often necessary to
generate a situation of interest.
Any change in the Servo Tyer controller settings made from the PC except “TIME” and
“DATE” will be forgotten when power to the Servo Tyer controller is turned off, providing
that Dip Switch 5 on the Auxiliary Board of the Servo Tyer is in the “ON” position.
At various times, you will see statements on the screen of the PC that refer to Motor 1,
Motor 2, Motor 3 and Motor 4. These refer to the 4 servo motors being controlled.
Motor 1 refers to the motor that drives the needle.
Motor 2 refers to the motor that drives the twister hook.
Motor 3 refers to the motor that drives the holder shear.
Motor 4 refers to the motor that drives the bag gathering belts.
The AC motor that drives the gathering brushes is not a servo motor and it is not under
the command of the Servo Tyer controller.
