5. AH27 User Manual Preface Please read this manual carefully also with related manual for the machinery before use the controller CAUTION For installing and operating the controller properly and safely qualified personnel are required This product is designed for specified sewing machines and must not be used for other purposes If you have any problem or any comment please feel free to contact us Safety Instruction 1 All the instruction marked with sign N must be absolutely observed or executed otherwise personal injuries or risk to the machine might occur 2 This product should be installed and operated by persons with appropriate training only 3 Before connecting power supply cords to power sources its necessary to make sure that the power voltage is in the range indicated on the product name plate 4 Make sure to move your feet away from the pedals while power on 5 N Turn off the power and remove plug prior to the following operations Connecting or disconnecting any connectors on the control box Repairing or doing any mechanical adjustment Threading needle or raising the machine arm Machine is out of work 6 Make sure to fasten all the fasteners firmly in the control boxes prior to the operation of the system 7 Allow an interval of at least 30 seconds before repapering the system after power off Pagelof16 8 Repairs and maintenance work may be carried out by special trained el
6. ectronic technicians 9 All the replacement parts for repairing must be provided or approved by the manufacturer 10 The controller must be firmly connected to a properly grounded outlet Be sure to connect the controller to a properly grounded outlet If the grounding connection is not secured you CAUTION may run a high risk of receiving a serious electric shock and the controller may operate abnormally 1 Product Introduction 1 1 Overview These Series Digital AC Servo System consist of motor and controller which are separately mounted on the same bracket providing a very flexible mounting solution for customers The system can execute needle down or needle up position with external synchronizer And it can be easily configured with different motors to match with various sewing machines such as lockstitch dual needle lockstitch heavy duty over lock stitch interlock stitch and direct driven sewing machines Employing a switch mode power supply for the sensitive control circuitry the system can operate over a much wider voltage range It has the following advantages installed easy large torque small size low noise high efficiency small shake and high precision speed control Side mount connectors make the connection more reliable and reduce the malfunction caused by oil leakage 1 2 Specification Controller Type AH27 55 AS27 70 75 Max Sewing Speed 5000 3500 r min Voltage Range C 22044 V 50 60HZ O
