KUKA Sunrise Cabinet Med is a robot controller launched by KUKA for medical device manufacturers, specifically designed for operating LBR Med lightweight robots. It adopts a 19 inch chassis, weighs about 23 kg, has a protection level of IP20, and an average noise of about 54 dB (A). The power supply is 110 V/230 V AC single-phase, with an allowable deviation of ± 10%. The frequency is 50 Hz ± 1 Hz or 60 Hz ± 1 Hz, and the rated power is about 1 kVA. The maximum heat dissipation is 370 W. It is recommended to use 2x16 A slow melting on the power supply side and 2x10 A slow melting on the equipment side. The control cabinet must be connected to a power system with a grounded neutral point, which belongs to Class I protection equipment. The operating environment temperature is from+5 ° C to+45 ° C, the storage and transportation with batteries is from -25 ° C to+40 ° C, and without batteries is from -25 ° C to+70 ° C, with a relative humidity of 5% to 85%. Below an altitude of 1000 meters, there is no need to reduce the rating. Below 3000 meters, the rating will be reduced by 5% per 1000 meters. The controller can be installed in a 19 inch rack with a depth of at least 600 mm, and a 70 mm cooling air gap must be left on both sides. When installed vertically, the fan opening and ventilation duct must not face upwards. For medical equipment manufacturers and on-site engineers, mastering their medical integration requirements, safety interfaces, maintenance cycles, LED diagnostics, fuse specifications, and component replacement processes is key to ensuring the safe and reliable operation of the system.
Key points of system architecture and medical integration
KUKA Sunrise Cabinet Med consists of a control PC, CCU_SR, low-voltage power supply, battery, fan, interface, and connection panel. The control PC adopts D3445-K motherboard, providing 4 USB 2.0, 2 USB 3.0, Display Port, DVI-D, and LAN Onboard interfaces. CCU_SR stands for Small Robot Cabinet Control Unit, consisting of CIB_SR and PMB_SR. It is the central power distribution and communication interface, responsible for safety input and output, contactor activation, 3 floating outputs, 7 safety inputs, teaching pendant connection, power fan monitoring, and temperature detection inside the control box. The low-voltage power supply supplies power to the control cabinet components and provides 48 V DC for the robot drive, with two green and two red LEDs indicating the working status. The battery maintains a controlled shutdown in case of power failure, charges through CCU_SR, and checks the battery level.
In terms of medical integration, KUKA Sunrise Cabinet Med is only allowed to operate LBR Med and is integrated into medical devices by medical device manufacturers. It has passed the CB system test and comes with a CB test certificate, and only the software components specified in the CB test report are compatible with each other. Medical equipment manufacturers must ensure that devices connected to the controller interface meet the isolation requirements of IEC 60601-1: 2 x MOOP and 1 x MOPP, based on a maximum 230 V AC power supply voltage, corresponding to at least 3.4 mm electrical clearance, 5.0 mm creepage distance, and 3000 V dielectric strength. When connecting devices, medical equipment manufacturers must verify that the leakage current limit complies with IEC 60601-1 and consider the requirements of the ME system. The controller interface only allows connections to devices that meet the operator's protective measures, and devices that require patient protection measures must not be connected to the controller interface. Medical device manufacturers must also evaluate the entire system, including all devices connected to interfaces, during the risk management process. The controller must not be accessed by patients or unauthorized personnel, and an additional cover plate should be used, which can only be opened by maintenance personnel using tools. The controller is not suitable for direct operation in a sterile environment. If the intended use of the medical device requires it, the medical device manufacturer must take additional measures, such as attaching a casing.
Security features and X11 interface
The safety oriented function of KUKA Sunrise Cabinet Med complies with EN ISO 13849-1 Category 3 and Performance Level d, as well as EN 62061 SIL 2. The safety oriented function is used to protect personnel and must be tested at least once a year, unless otherwise specified in the workplace risk assessment. The test objects include local emergency stop devices, teaching pendant enabling devices, manual guidance enabling devices, external enabling devices, smartPAD mode selection switches, and safety oriented outputs of discrete safety interfaces. The non safety oriented function is used to protect the machine, including mode selection, T1 speed monitoring, and software limit switches. The speed monitoring limit in T1 mode is 250 mm/s, and 250 mm/s is pre configured for manual guidance, but can be adjusted according to risk management. The software limit switch is only used for machine protection, and stops under servo control when the axis exceeds the limit.
