- Meet various applications
1. Digital Speed ​​and Position Control Loop This function synchronizes the speed or position of multiple drives. In extrusion, wire drawing and textile production, actual tension or compression control is controlled by the relative displacement of the shaft or the adjustable speed ratio.
2. Central reeling realizes constant reel tension control for unwinding or reeling, which is mainly used in industries such as paper making, wire rods, plastics and metal processing, etc. Contact adjustment of the output torque of the drive unit to changes in reel diameter, mechanical losses and reel inertia Make compensation.
3. Rotary axis positioning The user can set the final position of the motor shaft relative to the electronic feedback reference point. For example, the reference point can be the positioning pulse sent by the encoder. Simply modify the corresponding parameter value to adjust the position of the shaft. After the positioning is completed, the drive outputs an indication signal. This feature is widely used in CNC machine tool replacement or Other automation applications.
4. Excitation controller
The M25-M210(R) series drives are equipped with a standard MDA3 excitation controller. The excitation controller controls the motor excitation current, such as achieving constant power control. This function is particularly useful for applications that require constant power control, such as machine tools, mixers, decoiling, and take-up. The drive is equipped with excitation failure detection to achieve full protection, and full digital control facilitates debugging and operation. The M350-M1850(R) series drives are equipped with a fixed excitation power supply. For applications with excitation currents up to 20A, FXM excitation controllers are available.
5. S curve This function forms a curve pattern at both ends of the acceleration/deceleration ramp set by the user. The shape of the S curve of each quadrant is set by the specified parameter group, and the linear part and the curve part of the S curve are set separately. Due to the extreme speed and slowness of change, typical applications are cranes, cranes and conveyor belts.
