Video: Compact Actuators With Real-time Connection
The actuators offer extensive functions with a diameter of 80 mm (AG25), says Siko. The AG26 build slightly larger, but offer up to 13 Nm torque. The drives have a hollow shaft with a clamping ring for easy installation. Motor, gearbox, power and control electronics, as well as bus communication and position controller are integrated in the actuators, so that according to the manufacturer, only the bus connection and a 24 V DC voltage supply have to be supplied in the field.
Determine position when de-energized
In addition, a precise multiturn absolute encoder is integrated, which is to record the position of the drive shaft even when the shaft is turned when the actuator is de-energized. Even large travel ranges with 2500 revolutions and more should be possible without any problems. The actuators have two Powerlink interfaces with which they can be integrated into a line topology with daisy chain cabling. (jv)
