Actuator combines bus interface, absolute encoder
The Flexidrive actuator from Baumer electric combines a Profibus or CANopen interface, multiturn absolute encoder, dc drive and dc gear motor into a single unit. A PLC issues a position and a start command.
Then, the closed loop regulator system in the actuator takes over, comparing the setpoint with the current position and dynamically adjusts acceleration and speed. As the setpoint is approached, the motor slows down to allow precise positioning. Several gear reduction ratios are possible from 4:1 to 308:1, providing up to 15 Nm continuous torque from the 28 W motor.
