PP CN1A-3 Manual pulse
generator
NP CN1A-2
Used to connect the manual pulse generator (MR-HDP01).
For details, refer to section 14.1.8.
Override VC CN1B-2 10 to 10V is applied to across VC-LG to limit the servo motor speed.
Apply
10[V] for 0[%] override, 0[V] for 100[%], or 10[V] for 200[%].
Analog
input
Analog torque limit TLA CN1B
12
To use this signal, set any of MR Configurator (servo configuration
software) to make the external torque limit selection (TL) available.
When the analog torque limit (TLA) is valid, torque is limited in the full
servo motor output torque range. Apply 0 to
10VDC across TLA-LG.
Connect the positive terminal of the power supply to TLA. Maximum
torque is generated at
10V. (Refer to in section 3.4.4.) Resolution:10bits

Encoder Z-phase pulse
(open collector)
OP CN1A
14
Outputs the zero-point signal of the encoder. One pulse is output per
servo motor revolution. OP and LG are connected when the zero-point
position is reached. (Negative logic)
The minimum pulse width is about 400
s. For home position return
using this pulse, set the creep speed to 100r/min. or less.

CN1A
17
Outputs pulses per servo motor revolution set in parameter No. 27 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. 58.
