SETUP

6.1 Set IP Adress

To connect via ethernet to the embedded computer the IP adress of the PC has to be set to e.g. 192.168.3.1. Follow according guides in the web.

The embedded computer comes with IP 192.168.3.11.




OPERATION

7.1 Referencing

When the robot is not referenced cartesian motions and program replay are not allowed.

Reference the robot, see the documentation for details.

7.2 Reset and Enable

Press "Reset" and "Enable" buttons. A position lag error is normal after startup and referencing.

7.3 Referencing Joint5

When the referencing pin is too far away from the sensor the referencing takes long or might fail.

Manually position the referencing pin close to the sensor before starting the referencing.

7.4 Load Correct Program

When a wrong robot project is loaded the cartesian motions may not be correct.

Check if the loaded project fits to the used robot and load the correct one.

7.5 Define Zero Positions

If the zero positions are not correcly defined carteisn motions might be inaccurate.

To check perform a referencing and the move the joint to zero. Now the robot should be in a vertical / horizontal position referring to the joint holes.

If this is not the case adapt the offset in the amp parameter following the guide on the wiki.




MECHANICS / CABLES

9.1 Broken Connections

Check cables for broken connections or swapped connectors / cables.

9.2 Reverse Encoder Direction

Check if the encoder direction has to be changed in the amp firmware.

9.3 Loose Clutch

The clutch between the motor and the gear might be loose.

Turn the motor so that the screws can be accessed through the holes in the sheet metal around the clutch. Fasten the screws of the clutch. Apply loctite.

9.4 Add Lubricant

Add lubricant to the clutch to minimize motion sounds.

9.5 Replace Gear

The worm gear might be broken. Replace the broken part.

9.6 Reduce Sensor Distance

The distance between reference shensor and activating sheet metal might be too large. Reduce this distance.

9.7 Change Referencing Direction

The referencing direction if defined in the amp parameter by the entries RefSpeed and RefSpeedSlow. The referencing direction is reversed by changing the velocity from + to -, or otherwise around.



ELECTRONICS

10.1 Release Emergency Stop

Release the emergency stop and retry.

10.2 Check Motor Bridge

Check if the motor bridge cable to and from an E-Stop relay is in place.

10.3 Motor stall

The motor current is not high enough.

Increase the amp firmware parameter CSLoad and CSStart.

10.4 Overheating

The motor current is too high, the motor gets too hot.

Decrease the amp firmware parameter CSLoad, CSStart and CSIdle.

10.5 Wrong CAN ID

Check the adress switch on top of the electronic modules.

Motor modules should be 0, 2, 4, 6, 8.

Digital IO modules should be 0, 2, 4.

10.6 Firmware Parameter

Adapt the firmware parameter

10.7 Defect Electronic Module

Test another electronic module by swapping the connectors (not hot swapping, switch the robot control off before swapping). Check if the motor works with the new module it is connected to now. Replace the electronics module if it is the reason for the problem.

10.8 Corrupt SD Card

Information on the SD card of the display is missing.

Replace the SD card.
