360-degree controllableOvercurrent protectionMultiple working modes Acceleration start and stop function: the speed and acceleration value can be set, and the movement effect is softer. Multi-turn large angle precision control:With the highest accuracy, the absolute position control and feedback can be plus or minus 7 turns. Expanding the resolution value can achieve hundreds of turns of rotation. Note: After power failure, the number of turns is not saved, only the absolute position feedback value is retained. One-click calibration of the center position:360-degree installation at any position, 40-address input 128 to correct the current position to the middle position with one key. Very convenient installation, can improve production efficiency and reduce maintenance costs. (This function is only available for magnetic encoding, the potentiometer servo must be installed after the angle is adjusted before installation) Parameter feedback and protection:It has data feedback and protection for angle, temperature, voltage, current, and load, can capture the position of any angle of 360 degrees in real time, and is equipped with an alarm light for indication.
