DVSC-TT-14C-09 DOOSAN AC SERVO MOTOR/DRIVE VISION

For signal lines and encoder lines, use twisted lines or multi-core shielded twisted-pair lines. The length for command input lines should be maximum 3m, and the encoder line should be maximum 10m or less.
Wiring must be done in shortest distance and the remaining length should be cut.
▶ The ground circuit should be a thick line. Usage of third-class grounding or above (ground resistance 100Ω or less) is recommended. Also, make sure to ground at one-point grounding.
▶ The following precautions should be taken to avoid malfunction due to noise.
– The noise filter should be placed as near as possible.
– Mount a surge absorber to the coil of the relay, electromagnetic contacts, solenoids and etc.
– The power line (AC input, motor input line) and the signal line should be placed 30㎝ apart or more. Do not put them into the same duct or tie them in a bundle.
– If the power source of the servo drive is used in common with an electric welder or electrical discharge machine, or a high-frequency noise source is present, attach noise filter to the power or the input circuits.
– Since the core wire of the signal line cable is as thin as only 0.2 ~ 0.3㎟, excessive force to the line should be avoided to prevent damages.
