Robot Hardware Troubleshooting

Modular control electronics / robolink robots

Problem	Cause	Correction
Excessively jerky movement or acceleration and stall of the last joint of a robolink robot during initial set up of the robot	Wrong encoder direction	Swap encoder direction of this joint
Green LEDs on the rail modules are off	No power is supplied to the Modules	Check the power supply and the fuse.
Motors do not move	Check the emergency stop state. The red LED on the support module most not be on. The LED indicates emergency stop	Deactivate emergency stop.
The modules do not react to software commands. The green LEDs are not blinking, they are continuously on	There must not be an empty slot between the support module of the electronics and the joint modules. The CAN connection is interrupted by such an empty slot.	Ensure there is no empty slot between the modules
The motor stalls: it does not finish a motion and increases in pitch of sound.	This happens, when the load of the motor was too high.	Check if there was a collision. If this happens several times increase the motor current, see chapter 7 of the manual.
CPRog cannot connect	Another application may be using the CAN connection	Close or reset the PCAN-View software, if it is running.

If none of the above solutions have the desired effect, or you have further questions, please get into contact with us. We are happy to help.

email: In an email, next to a description of the fault, often pictures say more than a thousand words.
- A screenshot/photo/video of a particular error can help us a great deal and almost always speeds up the process to find the underlying cause of a problem and the solution. **The log files install.log, startUpLog.txt and logMessages.log are designed into the software to help in the diagnostics of a problem. They are located in C:\CPRog\ and are an invaluable tool for us to find solutions to software issues. Please include them in the support request, if applicable.

Phone: You can also give us a call under +49 5402 968929-0 (in Germany, GMT+1). If you have access to the robot while on the phone, this usually helps a great deal. In that way we can diagnose together and try out a potential remedy right away.
