Output signal

Output signal explanation
■LA/LAR (Encoder A-phase pulse (differential line driver))/LB/LBR (Encoder B-phase pulse
(differential line driver))
These devices output encoder output pulses set in [Pr. PA15] and [Pr. PA16] in the differential line driver type.
When the servo motor rotates in the CCW direction, the encoder B-phase pulse lags the encoder A-phase pulse by a phase of
3
90 degrees.
The relation between rotation direction and phase difference of the A-phase and B-phase pulses can be changed with the
servo parameter "Encoder output pulse - Phase selection".
[G] [WG]: [Pr. PC03.0]
[A]: [Pr. PC19.0]
Output pulse setting, dividing ratio setting, and electronic gear setting can be selected.
The maximum output frequency is 4.6 Mpulses/s.
■LZ/LZR (Encoder Z-phase pulse (differential line driver))
The encoder zero-point signal is output in the differential line driver type. One pulse is output per servo motor revolution. LZ/
LZR are on at the zero-point position.
The minimum pulse width is about 400 μs. For homing using this pulse, set the creep speed to 100 r/min or less.
Multi-axis servo amplifiers do not support this output signal.
■MO1 (Analog monitor 1)
This signal outputs the data set in the servo parameter "Analog monitor 1 output selection" to between MO1 and LG in terms
of voltage.
[G] [WG]: [Pr. PC09.0-1]
[A]: [Pr. PC14.0-1]
Output voltage: ±10 V
Resolution: 10 bits or its equivalent
■MO2 (Analog monitor 2)
This signal outputs the data set in the servo parameter "Analog monitor 2 output selection" to between MO2 and LG in terms
of voltage.
[G] [WG]: [Pr. PC10.0-1]
[A]: [Pr. PC15.0-1]
Output voltage: ±10 V
Resolution: 10 bits or its equivalent

■OP (Encoder Z-phase pulse (open collector))
The encoder zero-point signal is output in the open-collector type. One pulse is output per servo motor revolution. OP is on at
the zero-point position.
