[VFC66-Z] using the Phillips screwdriver (M3).
Warning
[Short circuiting on terminals]
●
Be sure to turn off VF66B (DC motor drive) before short-circuiting the terminals.
Otherwise, it can result in a risk of electric shock.

Caution
[Measuring voltage between terminals]
●
Sufficient care must be taken not to touch electrical wires and terminals when measuring the voltage
between terminals.
Otherwise
, it can result in a risk of electric shock.
After adjustment, turn off VF66B (DC motor drive), open the front cover, and remove the wiring installed between (AIN1)
and (+10) terminals of the terminal block [TB1] on the control print board [VFC66-Z] using the Phillips screwdriver (M3).

Measure the voltage between [AIN1] and [GND] terminals with a tester or other meters. Enter a value
1000 times the measured value. If the voltage cannot be measured, enter "9930" even though the
precision decreases.
