Position Controller SCON2
Functional Safety Unit SU
1. Newly Released Controller with Safety Monitoring Function for Safe Control of Single-Axis Actuators
Supports Safety Functions
This controller enables the use of a single-axis actuator without a safety fence*1 or a drive-source cut-off. Robots can work safely alongside people without stopping production.
*1 Supports risk reduction, NOT unconditional use without a fence.
Equipped with 14 types of safety functions, selected functions are introduced here based on application examples. Please refer to P.14 for more information on functions.
Parts conveyed by the single-axis actuator are placed on the workbench and sent to the next process after inspection.
SCON2 Controller Functional Safety Unit
This is a transport loader for machine tools. A single-axis actuator is used in the pre- and post-machining workpiece transport processes.
Application Example 1
Due to controller malfunctions, the actuator may run out of control and injure workers.
Risks
The use of SLS (safely-limited speed) enables stopping when the designated speed limit value is exceeded.
Safety Functions
Application Example 2
During maintenance, the actuator may run out of control and injure workers. SS2-t (safe stop 2-time control) is used. During maintenance, monitoring ensures the actuator does not operate in servo ON status. If it moves from the stop position, the drive source is cut off.
Safety Functions
Key Benefits:
-
Realizing Functional Safety with a Single Axis Actuator
Operation is simple. Equipment can be constructed at low cost. -
Safe Stopping Possible Without a Drive-Source Cutoff
Equipment life is extended; it can be repaired quickly and installed easily. -
No Fence Needed for Use of a Single Axis Actuator
People and actuators can share the same workspace. Production does not need to stop when approaching robots. Operation is also possible during maintenance.
Risks
Third-party certification obtained.
Note that this is limited to situations where a risk assessment has been conducted and risks have been reduced to an acceptable level.

3. Additional Features
-
Collision Detection Function
Collision is judged based on the two values below:- Feedback current value
- Difference between virtual position and present position
Collision judgment is now possible in all acceleration/deceleration sections as well as constant velocity sections.
Support planned as of 2024. Contact our sales personnel for details on the support schedule.
-
Force Control Push Setting
Push force can now be input in N units for pushing with force control in the positioner mode.
For pushing with current control, only % units can be input. -
IA-OS Teaching Software for PC
IA-OS supports everything from startup to troubleshooting. Connectable with computers with a commercially available USB cable.
SCON2 Controller Features
-
Comparison with Conventional Size | Comparison of 750W-spec controller size and installation interval (with 3 units installed)
SCON (750W specification)
Installation surface area: 45,396mm²
SCON2
Installation surface area: 19,200mm² (57% Reduced) -
Size
Can be connected to an actuator with a 200V servo motor mounted (60W to 750W). With a built-in fan, installation at a 1-mm interval (effectively zero) is possible, markedly reducing installation surface area within the control panel.

- How to operate actuators
- Cycle time calculation
- Press programs
- Troubleshooting, etc.
Additional Functional Features:
-
Actuator Recognition Function
Actuator information can now be confirmed with teaching tools. Some areas permit customers to write in freely, with writing to the actuator also possible.
Applies to products with manufacturing dates of 2024 or later on the manufacturing number sticker, and to actuators with a Battery-less Absolute Encoder equipped. -
Predictive Maintenance (Motor Overload Warning)
Equipped with a function that monitors motor temperature changes and issues a warning when motor overload is detected. Maintenance can be done after the warning is output in order to prevent failures and malfunctions in advance. -
Drive Recorder Function
This function makes it possible to record actuator behavior when an alarm goes off, contributing to cause analysis and rapid equipment recovery. -
Safety Functions Supported
The SCON2 controller is equipped as standard with an SS1-t function. As an electromagnetic relay is no longer required, this helps reduce installation space and extend equipment life.
Field Network Function:
The SCON2 controller supports the major field networks:
- Simple wiring
- Numerical management/numerical control
- I/O control also possible
Compatible Networks:
-
Modbus TCP Communication
Using the field network communication port, communication with the teaching software for PC IA-OS is possible. No dedicated cable is required, making maintenance easier as cables do not have to be disconnected and plugged in again.
