Claim of US Patent No. 9,160,574

1. A signal adjusting device for adjusting a detection signal which is output from a position detector to be used for a motor
control device, comprising:
a detection signal receiving unit for receiving a detection signal via a signal line; and
a termination resistor unit which is connected to a signal;
a changed value setting unit in which a changed value of a resistance value of the termination resistor unit is set in accordance
with an amplitude value of the detection signal received by the detection signal receiving unit and an amplitude value as
a reference value determined depending on a type of a position detector; and

a resistance value changing unit in which the resistance value is changed by using the changed value.
