(5) VCMD signal
The VCMD signal is used to output a speed command. It can also be
used to measure a very small vibration or uneven movement of the
motor. The VCMD signal conversion mode can be switched by a
parameter. Because the VCMD signal is clamped at +5 V, the
waveform may become difficult to observe. In such a case, switch for
easier observation.
