8.2 The hand often disconnects while the robot is moving
8.2.1 Problem
When the robot is stopped, the user interface shows that the hand is properly connected and you can use
it with no problem for teaching grasp and set waypoints; the device status card (from either the
installation tab or the toolbar on e-Series robots) display data correctly.
However, when you start a robot program it often happens that it stops saying that the hand is not
connected any longer.
8.2.2 Solution
There may be a couple of reasons for this unexpected behavior:
Some cables are not properly connected or secured, and robot vibrations when it starts moving can
cause faults in the communication channel;
If you are powering the device from an external power source, there may be some electrical noise in
your network that is not properly filtered out.
WARNING:
Be aware that you need to leave the system without power for at least 30 seconds during
the power cycle.
Only in this way we can assure that the system has completely reset its electrical state.

WARNING:
Be aware that the device must not violate our warranty policy, cf. maintenance and
warranty(see Page 25), in order to ensure the best support service for our customer.
Please, do not forget to mention in your request if you have made forbidden hardware/
software modification to the device before/after the issue — e.g. removing the glove cover is
forbidden, cf. forbidden actions(see Page 25). This will save you, and us, much time during the
investigation process.
