SS1 (Safe Stop 1) initiates a controlled deceleration to stop the motor *before* removing torque, then engages STO. SS1 is used when an uncontrolled stop could itself be hazardous.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan this drive be used in a non-safety application?\u003c\/strong\u003e\u003cbr\u003eYes, its safety functions can be disabled or not wired. However, you are paying a premium for the safety certification. For a pure performance application without safety needs, a standard MR-J3-11KB model might be more cost-effective.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat certifications does this safety amplifier hold?\u003c\/strong\u003e\u003cbr\u003eIt is typically designed to meet international standards like IEC 61508 (SIL 3) and ISO 13849-1 (PL e, Category 3). Always check the specific unit's declaration of conformity for the exact certifications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs external safety monitoring required?\u003c\/strong\u003e\u003cbr\u003eWhile the drive contains the safety functions, best practice often involves an external safety controller or relay to monitor the overall safety circuit, providing redundancy and diagnostics for the safety system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow does forced ventilation cooling work in a sealed safety cabinet?\u003c\/strong\u003e\u003cbr\u003eThe drive's fan circulates air internally over its heat sink. The cabinet itself must have adequate heat exchange, possibly via a cabinet cooler or heat exchanger, to remove the heat from the enclosed environment and maintain ambient temperature below 55°C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
