NOTE
1 If the SVM does not have an axis corresponding to a
pin on the check pin board, no signal is output to the
pin.
2 The voltage output using the motor current conversion
signal represents the actual current (sine wave)
flowing through the motor (4.0 V is output at maximum
current). This voltage cannot be measured with a
voltmeter (such as a VOM); use an oscilloscope.
