8.4 The hand is connected but does not move
8.4.1 Problem
The hand is completely open— i.e. it is in its resting configuration.
The user interface shows that the hand is properly connected and you can see the device status card
(from either the installation tab or the toolbar on e-Series robots) working correctly.
However the hand does not move even if the
"Hand Closure"
status bar moves accordingly with user
commands and the motor turns — i.e. you can hear its quite sound for something close to 1 second.
It may happen that the thumb (or the little) fingers move a bit from their rest configuration, but really far
from what is expected.
Also, the
"Motor Current"
status bar has really low values, even when you hear the motor moving.
8.4.2 Solution
If all the above conditions match your status, there may be a hardware fault which requires a qualified
service action.
To check whether you are on such a case or not you should perform this simple mechanical test:
Disconnect the hand from the power source;
Flex the fingers from index to little (all together) in the direction of the back of the hand — i.e.
opposite to the usual closure direction;
Repeat point (2.) several times and take care whether the thumb moves while doing such a
movement or not;
If the thumb does not move at all or move just a bit from itsrest configuration, you will need toraise a
"Service Request"
in our portal.We will do our best to ensure that this goes as quickly and as smoothly as
possible.
WARNING:
Be aware that trying to fix the problem by yourself leads to a violation of our warranty policy,
cf. maintenance and warranty(see Page 25), so please, just do not do it — e.g. removing the glove
cover is forbidden, cf. forbidden actions(see Page 25).
NOTE:
If all the previous conditions match the thumb should never move.
Anyway, if you think you have this problem but the thumb moves while flexing the other four
fingers together, follow the same steps as this other topic(see Page 27).
