1)    Use the EM9 frequency inverter safely in the textile, dyeing workshop, dusty and damp work environment, the inverter is well improved in structural design and the reliability is highly enhanced by isolating the control panel with the air duct of the module radiator, taking specialized dust and humidity prevention measures.

2)    The EM9 frequency inverter has wide voltage ranges which can be adjusted in 320 V-460 V. When power grid appears instant power down, EM9 inverter posses "non-stop instant" function which can use load inertia energy to let inverter running for some time. When power grid side is affected by lightning surge impact, EM9 inverter is with built-in lightning protection board which meet IEC61000-4-5 standard requirements has strong protection ability.

3)    For more motor cascade operation, the synchronous speed requirements EM9 all have multiple speed cascade synchronous way, have analog input and output, pulse column input/output and profibus communication. Given Frequency has rich calculation and auxiliary volume compensation function which can meet different users and different requirements.

4)    Comb cotton, roving, yarn and most textile equipment requires smooth start with fast brake ,EM9 inverter all have S form deceleration curve function, EM9 series can provide the rated torque under low frequency operation to 0.5 Hz,  ensure that the motor is smoothly operated; Realize the fast steady braking by using the the braking resistors and dc braking.

5)    Spinning machines requires muti-speed control, EM9 inverter is built-in 16 or 8 default given frequency which can be controlled by the external terminals or in accordance with the internal PLC instructions switch.

6)    Roving, yarn, and turn cup spinning and winding equipment need swing frequency output for making yarn cone evenly around the spindle, posed for frequency output EM9 is integrated swing frequency function, center frequency and the shape of the triangle wave can be set separately, which can be used together with internal PLC function or closed loop control function.

7)    Single spindle cone winding and knitting machine need automatic stop function when the machine is failure or full axis, EM9 is built-in counter function, when count as specified value can automatically start alarm or stop motion commands.

8)    The roller speed of the drawing fram must follow the changes of signal mouth thickness , EM9 closed loop control of torque response time is less than 100ms. Higher performance servo model frequency inverter is developing.

9)    Thick liquid yarn machine, intermittent dyeing machine and printing machine require wide range of speed control, tension constant EM9 can make automatic calculation of coil diameter, the inertia and tension of cloth, convenient to implement low cost of winding tension control system.

10)  Chemical fiber drafting equipment is required to keep the chemical fiber silk tension constant when operation or stop, EM9  have zero servo function and the tension control function.

 

11)  Chemical fiber production line, dyeing and transmission line post-processing equipment is required to frequency inverter dc bus plan to save braking resistance and energy loss EM9 converter is designed with terminals of the dc bus, which can be convenient to the connection and configuration of the protection devices, realize the public dc bus equilibrium solution.
