Thank you for purchasing EDS1000 series multi-function universal inverter
from our company Shenzhen Encom Electric Technologies CO., LTD.
1. EDS1000 series can fulfill all kinds of demand for general-purpose inverter
by advanced control manner which make high torque， high precision and
wide-range speed regulation drive be available. EDS1000 is organic combine of
customer’s general need and industrial requirement to provide practical PI adjuster,
simple PLC, programmable input output terminal control, long-distance
synchronous control, impulse frequency provision and other special inverter
control with powerful function for customer and to provide highly-integrated
incorporative solution of high value for reducing system cost and improving
system reliability for device manufacturing and automatization engineering
customers.
EDS1000’s big torque low noise and low electromagnetic disturbance during
operation can fulfill customer’s environmental protection requirement by space
voltage vector PWM control technique, speed sensorless vector control
technology and electromagnetic compatibility unitary design.
2. EDS1100 series inverter specialized for drawing machine is a kind of
inverter in cable industry for winding and rewinding control. Its internal real-time
computing module can automatically identify the coil diameter of the receive
volume, the wire diameter of drawing wire , according to the changes of winding
and rewinding of the roll diameter, automatically adjust the output frequency of
winding and rewinding of the inverter, to keep constant tension of winding and
rewinding cable.
Drawing machine can divide into large drawing machine, medium drawing
machine, slender drawing machine and micro drawing machine other four,
composes of drawing and taking-up two parts. To improve the quality of cable and
lower the cost, drawing machine is general from single frequency control to
dual-frequency control, and now most of the dual-frequency control is generally
used external PID control board, the shortcomings of this approach are: the
control parameters of PID board is difficult to debug, the control performance
depends on the level of debugging skill; Too many components and adjustable
potentiometers on the PID board are more prone to damage, repair and
maintenance costs are high.
EDS1100 series inverters specialized in drawing machine adopt a unique
