==Error message: Bus dead==
 
−
In general, the "bus dead" message in CPRog means that the CAN communication cannot be established. There are various potential causes for this:
 
−
* It is possible that no power is supplied to the robot. Causes may be one of the following:
 
−
**​The emergency stop button of any Mover robot interrupts ​the power supply to the robot (and therefore the CAN bus) when it is depressed. Rotate the red emergency stop button and pull to supply power to the robot.
 
−
**The fuse in the black fuse holder in the robot base has blown. A replacement fuse should be a fast/blow fuse 3.15A F, 20x5mm, such as https://uk.rs-online.com/web/p/cartridge-fuses/0563491
 
−
**The power cable coming from the mains may not be plugged in deep enough into the power supply. The external power supply has an LED that should light up when mains power is connected.
 
−
**The newer Mover robots have a blue LED at the base that indicates that power is supplied to the robot. Unfortunately Mover models prior to February 2017 lack this LED.​ ​
 
−
* The CAN adapter may not be plugged in to the PC or the driver may not be installed. When you see a red light on top of the CAN-USB adapter, the driver should be installed and the adapter should be working ok.
 
−
**LED on means: There's a connection to a driver of the operating system.
 
−
**slowly blinking means: A software application is connected to the adapter
 
−
**fast blinking means: Data is transmitted via the connected CAN bus​
 
−
* The connection between CAN adapter and robot may be interrupted.​
 
−
​* There may be a situation where the CAN driver has stopped responding. Shut down the PC, power off the robot, wait several seconds, start the PC and power on the robot.

Modular control electronics / robolink robots

What do the LEDs of the DIN Rail Modules indicate?

Problem Cause Solution
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 (=release) 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 the fault persists, restart the PC and power-cycle the robot.
