Follow the step-by-step guide to properly diagnose the error. Pay special attention to those tests
indicated in numbered boxes, and described in detail here below:
(1) Insert the oscilloscope probes between pins 5 (signal) and 6 of the CN2 connector on the Bio
servo board. With the motor enabled you should see a square wave signal ranging from
approximately 3.5 Vdc to 11.2 Vdc.
(2) Insert the oscilloscope probes between pins 10 (signal) and 2 of the CN2 connector on the Bio
servo board. With the motor enabled you should see a square wave signal ranging from
approximately 0 Vdc to 5 Vdc.
(3) Insert the oscilloscope probes between pins 10 (signal) and 2 of the K4 connector on the CPU
board. With the motor enabled you should see a square wave signal ranging from
approximately 0 Vdc to 5 Vdc.
