(iii) Rotate the motor in the reverse direction (clockwise)
and check that the following waveforms can be observed
at the nearly same speed as (ii) above.
(iv) Press the pushbutton switch PBl (see Reference 1.1(2)
and Appendix 6(l)) to reset the equipment to the
closed loop.
and check that the amplitudes of the signal outputs
for the forward rotation and reverse rotation are
(v) Check that the motor speed is the middle speed of
the base speed (approx. 1500 rpm) and the envelopes
of the signal waveforms of the phases A and B are
0.3 V or less.
The following figure exemplifies a waveform of phase
A.
B
Rotate the motor at the maximum speed
Phase
