Servo motor & # 8203; Electrical devices: in the field of practical application, we'll ever get to meet all kinds of problems, on the device consists of mechanical and electrical, if do not pay attention or do not standard, will affect the normal use of the encoder and become old, yea, the following instructions on the device to clarify in detail, more can help us use experience. Electrical interface: each electrical interface has its own characteristics, also have different baud rate and transmission interval, ability of using environment to choose according to the detailed, practical transmission interval and transmission rate, encoder and communication cable device of environment, grounding, cable materials, etc. Cable wiring: the encoder electric wire according to the parameter table of cohesion, not use to tie up the wires should be alone or to increase insulation sleeve, prevent damage due to with other signal or power cord short encoder. Encoder electrical wiring is necessary in the case of a complete power, charged pull plug connection head or cable, easy to damage the encoder. Power supply voltage is necessary in the rating range, long time use of high voltage is harm for the encoder. Power supply voltage is necessary to secure the mercy is not big, don't with high trouble components (Such as frequency converter, electromagnetic valve, contactor)Shared power, also can use filtering power supply. According to different using environment, choose the correct use of cable: (1)Drag chain in selection of towed cable trough, prevent damage of cable and socket mechanical; (2)Processing equipment on choosing oil resistant, coolant and cutting pieces of cable, prevent from cable plug line and encoder housing to assimilate into; (3)The encoder communication cable is to choose the special shielded cable. When encoder communication cable wiring, demand note: 1. Communication cable necessary to stay away from serious trouble magnetic field equipment such as motors, transformers, inverter; 2. Communication cable is necessary and the power cable, power cable and high noise cable laying, had better use shielding outstanding metal cable pipe sleeve; 3. Adhere to the minimum interval of 2 cm in electric cabinet and other cable, electrical cabinet 50 CMZ interval; 4. If space is limited, please use metal plate, metal casing and metal trough, and stick to outstanding grounding; 5. Want reasonable wiring, prevent the reserved cable is too long, forming slot plug; 6. To prevent coupling disturb, should try to reduce the signal cable and power cable possible parallel walk; 7. Cable should be arranged in the bearing interval of metal parts, such as control cabinet panels, beams and metal guide rail, etc. ; 8. It is necessary to use metal cable bracket, and ensure the stents conduction that cohesion; Component layout: the encoder device at the scene, not as high as the summits of frequency converter, transformers, solenoid valve trouble source device in together, and stick to the interval of 10 cm, or add metal diaphragm to isolation. With encoder communication module, when device in electric cabinet, is not as high as the summits of inverter, contactor disturb source element or open circuit switching element device frequently in together, insist on 3 cm intervals, or add metal diaphragm to isolation. Grounding protection: cable shielding layer should be done on the signal to accept end of single-end grounding, prevent the leakage current of damaged cable between the two pick up address; If the cable shielding wire can not reach a good grounding protection, needs to connect a ground wire for shielding alone; Grounding long interval of cohesion, requirements in the product increased yellow green line between shell and pick up address, as the equal electric potential compensation; Shielded cable is necessary cohesion electrical components at both ends of the metal shellEncoder may electrical cabinet)And ensure that the correct connection (Large area of contact with the metal surface); Installation instructions for each of the above as see in the field device and protection work, work efficiency, hope can help you progress to guard against the happening of the problem as soon as possible, to ensure the normal operation of the encoder.
