„ Explanation of each switch
[1] Address
switch
If multiple axes are used, the PC/teaching pendant must be plugged into/out of different connectors
to communicate with different axes.
To save the hassle, you can use link cables to connect all axes via SIO converters.
Under this method, however, the PC/teaching pendant must be able to identify each axis by the
number assigned to the axis.
This switch is used to set this number.
For details, refer to Chapter 9, “How to Connect a PC/Teaching Pendant to Multiple Axes.”
[2] Mode selector switch
This interlock switch is used to prevent unexpected movement or data rewrite as a result of duplicate
operation in which a movement command is input from the PLC and operation using the PC/teaching
pendant is performed at the same time.
AUTO: Always set to the “AUTO” side during auto operation using PIO signals from the PLC.
MANU: Always set to the “MANU” side during operation using the PC/teaching pendant.
[3] Brake release switch
When the actuator is equipped with a brake, this switch is used to forcibly release the brake.
RLS:
Forcibly release the brake
NOR: Normal setting (The brake is released by the controller.)
U Warning: The load may suddenly drop when the brake is forcibly released, so exercise due caution
not to pinch your hand or damage the work part or robot hand by the falling load.
„ Explanation of power-supply terminal block
[1] ACON-C [Positioner type (with internal drive-power cutoff relay)]
S1, S2
Provide a contact output for the emergency-stop button on the teaching pendant.
* Whether or not a teaching pendant is connected is determined by an internal
circuit. If no teaching pendant is connected, the S1 and S2 terminals are closed.
MPI, MPO
Provide a contact for cutting off the motor drive power. MPI and MPO represent the
input side and output side of the motor power supply, respectively. (Short these
terminals using a jumper wire if not used. The controller is shipped with MPI and MPO
shorted.)
24 V Positive side of the 24-VDC input power supply
0 V Negative side of the 24-VDC input power supply
EMG- Emergency-stop input
[2] ACON-CG [Safety category type (with external drive-power cutoff relay)]
S1, S2
Provide a contact output for the emergency-stop button on the teaching pendant.
* Whether or not a teaching pendant is connected is determined by an internal
circuit. If no teaching pendant is connected, the S1 and S2 terminals are closed.
MPI, MPO
Motor drive-power cutoff contacts conforming to safety category 1
MPI and MPO represent the input side and output side of the motor power supply,
respectively. (Connect an external safety circuit.)
24 V Positive side of the 24-VDC input power supply
0 V Negative side of the 24-VDC input power supply
EMG- Emergency stop signal detection
