PP CN1A-3 Used to connect the manual pulse generator (MR-HDP01).
For details, refer to Section 14.1.8.

VC CN1B-2 10 to 10V is applied to across VC-LG to limit the servo motor speed.
Apply
TLA CN1B-12 To use this signal, set any of servo configuration software to make the
external torque limit selection (TL0) 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
Signal Connector
pin No.
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.
LA CN1A-6 Outputs pulses per servo motor revolution set in parameter No. 27 in the
LAR CN1A-16 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
LB CN1A-7
of /2.
LBR CN1A-17
The relationships between rotation direction and phase difference of the
A- and B-phase pulses can be changed using parameter No. 58.
LZ CN1A-5 The same signal as OP is output in the differential line driver system.
LZR CN1A-15
MO1 CN3-4 Used to output the data set in parameter No.17 to across MO1-LG in
terms of voltage. Resolution 10 bits
MO2 CN3-14 Used to output the data set in parameter No.17 to across MO2-LG in
terms of voltage. Resolution 10 bits
