2.5.6. Analog input/output signal
The analog signal is based on 0 [V] (GND terminal) of the control circuit power supply. Connect
the GND terminal of the analog signal and the GND terminal of CN1. The analog speed
command input (CN1-27) rotates the motor at the speed determined by the ± Analog 10 [V]
Speed(P03-15, 16) menu. When +10 [V] is input, it rotates at the speed set in P03-15 in the
forward direction (CCW), and when -10 [V] is input, it rotates at the speed set in P03-16 in the
reverse direction (CW). The analog torque limit input (CN1-28) is activated when the analog
torque limit function (CN1-14) input contact turns on.
The analog torque limit value can be set in analog 10 [V] torque (P06-07). The torque limit
command input uses the absolute value of the voltage, so it is the same as the operation at 10
[V] even at -10 [V]. When wiring analog signals, twist the GND and signal lines using twisted pair
wires to minimize the influence of noise. The functions of each analog signal are shown in the
table below.

*1 : Speed control mode, *2 : Torque control mode, *3 : Position control mode
In order to apply speed command, speed limit, torque limit and torque command with variable
resistor, ± 12 [V] power is supplied through CN1 connector. The output capacity of this power
supply is 30 [mA] maximum. Do not exceed the maximum output capacity. The pin assignments
of the power supply are shown in the table below.
GND (CN1-1,8,26,33,34,36)
