In particular, our inverter models, which are torque control-centered, contain enriched functions such as internal PLC functions and heat sensor inputs, ammeter inputs for measuring current, pressure sensors, even if limited to the systems where you warp the windings and basic machines.
Although it is higher than the other models in our store in terms of price, it is in a very competitive position when compared to other manufacturers' products with similar features.
These models, which are very rich in parametric and have many function macros built-in, are relatively more difficult to use. There are videos and easy-to-use notes we prepared for the commissioning of these devices.
Why professional devices? (while more expensive)
In some critical applications, it is essential that the load pulling or releasing moment be stable.
In this type of loads, the load curve and the motor current change inversely with the speed. On the other hand, line current and motor power remain constant. As examples of such applications, we can give unwinding applications and lifting applications in cranes.
Why is torque inversely proportional to circuit?
For example: In winding applications, we always want the goods to be wrapped in constant tension. That is, the tensile force and linear velocity must remain constant. From the equation F*v=T*w, T=F*D/2 small torque in small diameter and large torque requirement in large diameter arise. In order for V to remain constant, it appears from the equation v=2*pi*n/60 *d/2 that as the diameter increases, n must decrease.
Therefore, since high torque, that is, motor current, is required in post-stop starts, it would be appropriate to choose the speed controller from 150% loadability, as in crane lifting motors.
Apart from that, 150% selection will be correct since the load curve is bumpy in applications such as eccentric press, saw and grinder.
If you do not need such features, our standard speed controllers have similar functions in our models.
