Troubleshooting: ERR2 - Motor Movement
Since the motor moves when you press speed up, focus on the optic sensor, its wire connections, and the
optic sensor wheel. If all seems well at the sensor, inspect the motor.
??? Optic sensor wheel - Make sure that the optic sensor wheel rotates securely, without wobbling, in the
middle of the optic sensor. Realign and tighten if necessary. If optic sensor wheel teeth are missing or
bent, replace the optic sensor wheel.
??? Optic sensor wires - Make sure that wires are inserted securely to the optic sensor and to the drive board.
Check wire continuity.
??? Optic sensor - Turn on unit power. Turn the motor flywheel with your hand. The optic sensor
indicator (LED10, drive board) should light. . If it does not light, and all parts above are
good, replace the optic sensor.
??? Motor arcing - Does the motor show signs of wear - irregular arcing, carbon dust?
??? Motor brushes - Do brushes show signs of irregular wear - cracks, dents, lines? Replace the
??? M+ M- Wires - Make sure wires are connected properly.
??? Display main IC - To ensure proper signal processing, press down on the main IC on the display
board, marked U5. .
??? Ribbon cable - Ensure that the ribbon cable is attached at the drive and display boards. Check cable
Troubleshooting: ERR 2 - No Motor Movement
Turn unit power off and then on to clear the ERR2 message from the display. To test whether the drive
board is putting out power to the motor, insert multimeter probes on the M+ M- connectors and press
the speed up key. . (Note: To avoid ERR2.)
Power to Motor
If the drive board puts out power to the motor, but the motor does not operate, either the motor wires or
motor is malfunctioning. Test wires for continuity. Inspect connections. Perform an ohm test on the
motor . Inspect motor brushes.
No Power to Motor
If there is no power to the motor, either the signal is not arriving at the drive board, the transformer
or inductor is bad, or the drive board is bad. Inspect the following:
??? Display - Does the display beep when you press speed up? If so, the display has sent its signal.
If not, inspect overlay-to-display connections. And press down on the main program IC, marked U5.
??? Wires and their connections - inspect data cable connections from the display to the drive board,
test data cable continuity, inspect M+ M- wires from the drive board to the motor.
??? Inductor (6310 only) - inspect inductor and its wires and their connections. .
??? Transformer - inspect the transformer and its wires and their connections.
??? Drive Board - inspect the drive board for burnt or cracked components. Inspect LEDs (See DRIVE.03
and DRIVE.04). Press on the drive board IC chips to ensure good connection. If the power indicator on
the drive board, LED8, lights, but there is no power to the motor, and other components are good,
replace the drive board.
