Check that the FlexPendant cable is correctly
connected to the controller through the HMI signal
connector, X4.
Check the LED PC and LED HMI, they should be
green.
Check the FlexPendant cable for any damage.
Check that the connection from the robot signal
exchange proxy to the HMI signal connector is
ok, K2.X9, 13 - X4.
Check that the connection from the robot signal
exchange proxy to the main computer is ok:
• K2.X8 - A2.X6
• K2.X2 - A2.X1
• K2.X12 - A2.K3.X6,7
• K2.X3 - A2.K3.X1
If possible, test by connecting another FlexPend-
ant. This is to eliminate the FlexPendant and cable
as error sources; Test the FlexPendant with a
different controller to eliminate the controller as
error source.
