(Note 2) When 2-phase pulse is used, maximum frequency of phase-A and B are different
(32kHz for A-phase, 2kHz for B-phase). In order to detect rotation direction over 2kHz,
choose detection methods in P004.

90° ph. difference 2-ph. pulse train 2
(Note 3) For rotating coordinate system, if "01" is set in P075, the rotation direction of shorter
routing is selected. In this case, set the number of pulse for one rotation in position-0
(P060). This value must be positive number. When "01" is set in P075, p004
.
or 01
(Note 4) d030 is cleared by inputting PCLR, SPD, ORG, RS signal or turning on the power
supply.
When "00" is set in p004, PCLR is effective only during the RUN command (FW, RV) is
given.
(Note 5) P075 is to be set higher when speed detection is not accurate in low speed.
