Following Errors are one of the most commonly reported errors. Several weeks ago, we published a blog post pertaining specifically to Troubleshooting Following Errors on Stratus Wrappers. While this topic was very well received and helpful for those of you with Stratus wrappers, what about those of you with Linium wrappers? This week, we will provide a few simple steps to Linium (PC-104) Open Loop Diagnostics.

As discussed previously, a Following Error is generated by the machine motion controller triggering incorrect feedback from the motor to the computer.

The Open Loop diagnostic allows maintenance personnel to select a motor, enter a voltage (velocity) and run the motor (enable). Once the desired motor is selected, the velocity is set, and the enable is set to yes, pull out the emergency stop button. Press and hold in the start button. The selected motor will run in an open loop mode as long as the start button is held in.

Access the “Diagnostic Open Loop” screen to display information helpful to diagnose motors and encoders.

Note: The Emergency Stop button must be pressed in before entering this diagnostic for the function to work.

The diagnostic screen displays the following information:

Motor: Turn the Press-To-Accept knob to select the desired servo motor drive (infeed, finwheels, or cutting head; power feed roll and discharge motors are not servo motors and cannot be tested with this diagnostic).

Velocity: Indicates the desired analog voltage being sent to the motor drive. Turn the Press-To-Accept knob to change the analog voltage.

Enable: To start the diagnostic, rotate the Press-To-Accept knob to display “Yes”. This will enable the drive.

Encoder: Indicates the encoder position of the selected motor. When the motor is rotating in the correct direction, this value should be incrementing.

Direction: Indicates the status and direction the motor is rotating. When the motor is rotating, it should display “Forward”.

And just like that, you’re back in business! Continue to watch for future posts pertaining Following Error troubleshooting as well as other tech tops for Bosch Wrappers. If you are interested in tech tips not specific to Following Errors, inquire and we will publish a blog that can be helpful for everyone!

A Following Error is generated by the machine motion controller triggering incorrect feedback from the motor to the computer.  In Layman’s terms, the motor was commanded to move to a specified point in a specified amount of time, if it does not get there in the correct amount of time, a fault occurs, and this is called a Following Error.   A simple product jam or mechanical failure may cause a Following Error resulting in unnecessary downtime.  Should this fault occur, do you know how to quickly and effectively diagnose the problem?

Open and closed loop speed commands are used to troubleshoot motors, cabling, amplifiers, resolver feedback, and wiring associated with the close loop feedback.

By using the diagnostics drive setup, a small voltage can be sent to an individual axis without the machine homed or synched. By monitoring the direction on the drive set-up screen you can also verify the correct encoder feedback. Note: All the amplifiers cabling and motors are the same. Cable swapping can be done to easily identify a bad component.

Note: Machine must have power off and locked out while swapping cables.

The below picture is an example of moving the cutting head motor cable and feedback to the finwheel drive. Once the cables are swapped output a speed command from the finwheel axis to verify if the motor or the amplifier is the problem.

Perform the following steps to access the diagnostics screen and the drive set-up screens:

Step 1: Press the diagnostics key on the control panel. (Figure 1 screen will appear.)

Step 2: Rotate the press to accept button until the drive set-up is highlighted.

Step 3: Push the press to accept button. (Figure 2 screen will appear.)


Step 4: By rotating the press to accept dial, select the axis you wish to run and set the enable motion on.

Step 5: Set output voltage to approximately 1 volt and press start.

Note: All emergency switches have to be pulled out and guard switches closed.

Do you have a legacy machine that you just can’t part with? Or, are you looking for a Bosch wrapper but don’t have the resources to buy new? Bosch Packaging Services remanufactures equipment to like-new condition for a fraction of the cost compared to new. Check out the before and after photos of this remanufactured 1991 Microtronic.

All remanufactured machines are completely dismantled and reassembled. Painted parts are sand blasted and powder coated; sheet metal and plated parts are refinished or replaced. Rubber rollers are surfaced to original specs. A complete controls upgrade to current new machine controls platforms comes standard on all remanufactured machines. All new wiring, pneumatic components and plumbing, bearings, bushings, pulleys, sprockets, chains and belts are replaced with new as well as any worn or damaged parts. Remanufactured machines are customized to your product specifications and include crimpers, knives/anvils, product spacer, former and infeed product guides.
