Product Dimensions：

The MR-J3-D05 serves as a plug-in safety module that expands the protective capabilities of the MR-J3 servo drive. While the standard J3-B-Safety amplifier inherently supports Safe Torque Off (STO), the addition of the D05 unit enables more complex safety sequences such as Safe Stop 1 (SS1). It acts as a bridge between safety input devices (like E-stop buttons or light curtains) and the servo drive, managing the deceleration and power shut-off logic internally.

Product Parameters

Digital Outputs: 4 x STO outputs (STO1A/B, STO2A/B) and 4 x monitoring outputs (SDO1A/B, SDO2A/B)
Safety Delay Times: Configurable for A-axis (0 to $30.8 \text{ s}$ over multiple steps) and B-axis (0 to $30.8 \text{ s}$ )
Safety Functions: Safe Torque Off (STO), Safe Stop 1 (SS1), Emergency Stop, and Emergency Off
Included Accessories: CN9 and CN10 connectors
Operating Temperature: $0\text{°C}$ to $+55\text{°C}$
Environmental Rating: IP20 (intended for installation inside a control cabinet)

Product Advantages

Advanced Safety Integration: Enables SS1 (Safe Stop 1), which allows the motor to be stopped using a controlled deceleration before removing power, reducing mechanical stress compared to a sudden coast-to-stop.
Simplified Wiring: By handling safety logic within the module, it reduces the need for complex external safety relay hardwiring, saving space in the control panel.
Dual-Axis Independence: The unit can manage safety functions for two separate axes independently, providing flexibility for multi-axis machinery.
Standard Compliance: Helps systems achieve compliance with EN ISO 13849-1 Category 3 PL d and IEC 61508 SIL 2.
High Reliability: Features built-in feedback and monitoring circuits to ensure the safety integrity of the shut-off chain.

Important Considerations

Professional Installation: This unit must only be installed and configured by qualified personnel familiar with automation safety standards.
Residual Voltage: Before inspecting or wiring, turn off the power and wait at least 15 minutes for the charge lamp to turn off, as the servo amplifier retains high-voltage energy.
Enclosure Requirements: The unit must be installed in a clean, dry control cabinet (IP54 or higher) to protect against dust, oil mist, and conductive contaminants.
Parameter Settings: Ensure the delay time settings for SS1 match the deceleration capabilities of your specific motor and load to prevent safety failures.
Grounding: To prevent electric shock, always ensure the protective earth (PE) terminal is securely connected to the cabinet's ground.

Product Applications

The MR-J3-D05 is widely used in high-precision industries where human-machine interaction is frequent or where equipment protection is critical.

Semiconductor Manufacturing: Protecting sensitive wafers during emergency stops by ensuring controlled deceleration.
Packaging Machinery: Used in bottling and labeling lines to allow operators to clear jams safely without fully de-energizing the entire machine.
Machine Tools: Providing safe stop functionality for high-speed spindles and axes in CNC environments.
Robotics and Handling: Managing safe zones and emergency stop sequences for multi-axis pick-and-place systems.
Textile and Material Processing: Ensuring that high-inertia rollers or cutters stop safely in the event of a safety gate breach.
