3.3.3 CN1 Terminal signal description
This section introduces the signals which mentioned in section 3.3.1.
1.
CN1 terminal signal
The detailed description of each signal in CN1 50Pins is as follows
The codes of the control modes in the following table are:
Pt : position control mode/ position mode(terminal input)
Pr : position control mode/position mode(internal register)
S: speed control mode
T: torque control mode

CN1-1
CN1-26
Output DC15V from VCC-LG. It can be
used as power supply for TC, TLA, VC,
VLA.

VC/
VLA
CN1-2
It applies voltage of DC -10V~+10V
between VC-LG. In S mode, the motor
runs the PC12 setting speed at ±10V.
It applies voltage of DC -10V~+10V
between VLA-LG. In T mode, the motor
runs the PC12 setting speed at ±10V.

LG
CN1-3/4
/28/31
It’s common pin of TLA, TC, VC, VLA,
OP, MO1, MO2, VCC. And each pin is
connected internally.
ALL
Analog torque
command/limit
TC/
TLA
CN1-27
To output or limit the torque of servo
motor.The voltage of TC-LG is DC 0-
10V. Maximum torque will be generated
at ±10V(the torque generated at ±10V
can be changed by PC13). When the
analog torque limit (TLA) is valid, the
servo motor torque will be limited in the
entire range.
The voltage of TLA-LG is DC 0-10V.
Maximum torque will be generated at
+10V if TLA is connected to the positive
polarity of the power supply.
