[10] AUTO/MANU switch
The operating mode using the teaching pendant/PC (software) connected to the SIO connector, and PIO
input, will change as follows in accordance with the setting of this switch.
Prohibition/permission of PIO activation is specified using the PC software/teaching pendant.
PIO activation inhibited
(teaching mode 1 or teaching
mode 2)
All operations are possible using the PC software/teaching pendant.
PIO inputs are not accepted.
MANU
PIO activation permitted
(monitor mode 1 or monitor
mode 2)
Only monitoring operations are possible using the PC
software/teaching pendant. PIO inputs are accepted.
AUTO
Only monitoring operations are possible using the PC software/teaching pendant. PIO inputs are
accepted.
* The emergency stop switch on the teaching pendant is enabled when the switch is connected,
regardless of the AUTO/MANU mode. Take note that although an emergency stop is actuated
momentarily when the teaching pendant or SIO cable is removed, this does not indicate an error
condition.
Therefore, the actuator and other equipment that are currently operating will stop.
Do not disconnect the teaching pendant or SIO communication cable while an actuator or any other
equipment is operating.
[11] SIO connector
This connector is used to connect the dedicated communication cable for teaching pendant/PC. It is also
used when two or more controllers are linked via serial communication.
[12] Brake release switch
This switch forcibly releases the electromagnetic brake of an actuator with brake.
RLS: Power is supplied to the brake to forcibly release the brake.
NOM: The controller controls ON/OFF of the brake. This setting should be used in normal conditions of use.
* A 24-VDC power supply must be connected to drive the brake.
Even if the controller power is not turned on, you can still move the slider or rod manually by turning on
the 24-VDC power supply for driving the brake and then forcibly releasing the brake.
[13] Brake power connector
This connector supplies the 24-VDC brake power. If an actuator with brake is connected, 24 VDC must be
supplied externally.
MC1.5/4-G-3.5
(Phoenix Contact)
* Turn on the 24-VDC brake power before turning on the SCON controller power.
[14] Encoder/sensor connector
This connector is used to connect the encoder/sensor cables of the actuator.
With the SCON, encoder voltage is adjusted using a parameter (one of four levels is set in accordance with
the encoder type and cable length).
