1. Torque sensor reference voltage display
a. “10” is displayed in the diagnosis mode dis-
play
1
of the display unit.
b. Press the function select switch “
s
” of the
display unit.
c. Displayed in units of 0.1 V from 0.0 to 5.0 V in
the diagnosis data display
2
of the dis play
unit.
d. The torque sensor is normal if the display
voltage is 0.2 to 1.1 V.
Perform a torque sensor reference voltage
adjustment if values outside of this range are
displayed.
e. Press the light switch “
” of the display unit.
f. Proceed to “2) Motor current”.
2. Torque sensor reference voltage adjustment
function
Turn the power on to the display unit and let it
stand.
Guideline: Until the power to the display unit
is turned off automatically (about
5 min.).
TIP
Do not place feet on the pedals while perform-
ing a torque sensor reference voltage adjust-
ment.
* Determining whether or not the torque sen-
sor is good
0.2 to 1.1 V = normal
If the torque sensor is outside of this range
→
Implement the torque sensor reference
voltage adjustment function.
If the torque sensor remains outside of its
normal range after torque sensor reference
voltage adjustment
→
Torque sensor malfunction (replace)
