Press the Green Servo On button. You will hear the robot’s brakes release with a distinct "clunk." Keep holding it. (Note: On older Yushin controllers, you may need to press a "Reset" button first to clear past alarms).
While in portable manual mode, you are holding the Servo On button. If you release it, the brake engages instantly. However, if the robot loses power or the emergency stop is pressed while the arm is extended into the mold, the Yushin anti-drop safety valve (a mechanical check valve on the vertical cylinder) should engage. Never trust this 100%. Always install a mechanical safety prop (a "C-clamp" lock) if you will be under the robot arm in manual mode for more than 30 seconds.
| Interlock | Behavior | |-----------|----------| | Enabling switch released | Servo power OFF, brakes engaged, robot holds position (does not drop). | | Emergency stop pressed | Power to servos and pneumatic valves cut. Air dump valve exhausts. | | Safety gate open (while on MANUAL) | Pendant remains active but speed limited to 20% (Yushin safety logic). | | External emergency (e.g., mold protection sensor) | Robot ignores pendant inputs; requires reset on main panel. |
Best Practices for Using the Manual Portable: yushin robot manual portable
To prepare documentation or use your Yushin robot's portable controller (teaching pendant), you can refer to the operational details for specific models like the E-touch series or G-II. These handheld terminals are designed for teaching, manual operation, and monitoring mold-related data. Portable Controller Models
E-touch V: A high-end handheld controller featuring a smartphone-like touchscreen with tap and swipe capabilities. It includes ambidextrous grips and diagonal enable switches to reduce fatigue during long teaching sessions.
E-touch II: A durable, IP44-compliant model with a 10.4-inch display, weighing approximately 1.4 kg. It includes two enable switches, a Servo ON button, and an Auto/Manual mode switching key. Press the Green Servo On button
E-touch Compact II / Lite: A lighter, 1.2 kg portable unit with a 7.5-inch display. It is designed for ease of use in tighter spaces while maintaining full control over axis movements and programming.
G-II: A compact handheld terminal from the G-Series with a high-contrast LCD and tactile silicone buttons for use in environments where contaminants might be present. Key Operations for Manuals Yushin FRA Robot: Precision & Safety | PDF - Scribd
Since "Manual Portable" typically refers to the Teach Pendant (the handheld device used to control the robot manually), this guide focuses on the operation, safety, and maintenance of Yushin portable teaching devices. The Yushin Manual Portable is a handheld terminal
The Yushin Manual Portable is a handheld terminal hardwired (or optional wireless) to the robot’s main control cabinet. Unlike the fixed operation panel, the portable unit allows the operator to stand directly inside the mold area or the take-out zone to perform three critical tasks:
Safety Note: The portable unit typically has a 3-position enabling switch (Deadman switch) on the back. The robot will only move when this switch is held in the middle position.
When operating a Yushin robot manually via the portable unit, strict adherence to safety rules is mandatory to prevent collision with the molding machine or injury to the operator.
In the high-speed world of plastic injection molding, downtime is the arch-nemesis of profitability. Yushin Precision Equipment Co., Ltd. has long been a titan in the field of industrial automation, specifically regarding sprue pickers and traverse robots. While most operators are familiar with the pendant (the handheld controller), the concept of the Yushin robot manual portable unit refers to the specific operational mode and hardware that allows technicians to control the robot independently of the automatic cycle.
Whether you are a veteran maintenance engineer or a new setup technician, understanding the "Portable Manual Mode" is critical for troubleshooting, end-of-arm tooling (EOAT) setup, and crash recovery. This article serves as a deep-dive manual for operating Yushin robots (specifically models like the YSX, YSN, or HA-80 series) in a portable, manual capacity.
