Excessive absorption peaks of the gearmotor, check that there are no obstacles throughout
the movement of the bar, check the motor's absorption of current when loadless and applied
to the bar;
• 5 flashes:
Check wiring, check encoder through TEST-ENCODER (optional)
• 6 flashes:
Check that there are no obstacles throughout the movement of the bar and the balance of
the bar;
