- DIGITAL DC DRIVE: exponential DC drive, indicating that the DC drive adopts digital control technology, can control the running state of the motor more accurately.
-DC 4Q: This represents the motor control mode. 4Q means four-quadrant control, which means that the DC drive allows the motor to operate in positive and negative torques and speeds in positive and negative directions. This control mode is usually used for motor positive and negative switching, braking and other applications.
