Double drive low voltage servo driver

Dual DC servo driver

24V 800W 48V 1500W Servo driver

Summary:

Kydbl4875-2e is a high-power intelligent dual channel servo driver. The low-voltage servo driver can control two DC brushless servo motors at the same time. The internal uses 32-bit high-performance MCU and advanced motion processing algorithm to realize the internal electronic differential function. The controller uses the hall signal inside the motor as the rotor position feedback, and cooperates with the external incremental encoder (1000-2500 lines) signal to control the motor movement, so as to realize the speed open-loop, closed-loop mode, position mode and torque mode. Two independent driving chips, two encoder processing chips and two hall signal processing chips. At the same time, it has a variety of fault alarm functions.

There are two working modes: independent mode and mixed mode. Independent mode: the two-way motor can be completely controlled independently, and the control signal part is two-way input signal control. The speed and direction of the motor can be controlled by two DC BLDCM. Hybrid mode: it can realize synchronous control of two sets of BLDCM (forward, backward, left and right rotation). There are 8 kinds of control signals (wireless remote control, rocker, potentiometer, analog quantity, frequency, pulse width, RS232, can bus).

Product features:

◆ wide voltage input, 10-55v, max60v overvoltage protection.
