CN3-7
CN3-17
Outputs pulses per servo motor revolution set in parameter No. PA15 in the
differential line driver system. In CCW rotation of the servo motor, the encoder
B-phase pulse lags the encoder A-phase pulse by a phase angle of /2.
The relationships between rotation direction and phase difference of the A- and
B-phase pulses can be changed using parameter No. PC03.
Output pulse specification and dividing ratio setting can be set. (Refer to
Section 5.1.9.)
Encoder Z-phase
pulse
(Differential line
driver)
LZ
LZR
CN3-8
CN3-18
Outputs the zero-point signal in the differential line driver system of the
encoder. One pulse is output per servo motor revolution. turns on when the
zero-point position is reached.
The minimum pulse width is about 400 s. For home position return using this
pulse, set the creep speed to 100r/min. or less.

Used to output the data set in parameter No. PC09 to across MO1-LG in terms
of voltage. Resolution 10 bits
Analog monitor 2
MO2
CN3-14
Used to output the data set in parameter No. PC10 to across MO2-LG in terms
of voltage. Resolution 10 bits
