RD6 is the first intelligent positioning drive without gears in the range of Lika Electronic. The Standard NEMA 23 size flange and the 8-mm shaft in fact are designed to be coupled with 1-, 2- and 3-stage planetary gearboxes available in the market, to be mounted between the motor and the user's installation. So it can be easily integrated in customized applications to meet specific torque, speed and precision requirements. It can be even coupled with angular gears. RD6 features a space-saving design with rugged anodized aluminium housing for high IP54 protection rate and installation in demanding industrial environments. The compact frame fully integrates the BLDC motor, the absolute multiturn encoder, the position closed-loop controller and the fieldbus interface. The 24VDC brushless motor has 100 W rated power, 0.426 Nm rated torque and 3000 RPM; while the measuring system provides an overall 28-bit resolution (4096 counts / turn per 65536 revolutions of the motor shaft). The well-proven position controller brings many valuable benefits. It boasts two cascade control loop cycles, i.e. a 1 ms position loop cycle and a 200 µs current loop cycle. Furthermore the internal trajectory generator (boasting a 64-bit double precision) allows the operator to set a new target position even on-the-fly. In addition controls include overtemperature, overcurrent, undervoltage and bus communication failure. In order to improve and even add new functionalities it implements the boot-loader feature, so the user can easily upgrade the firmware when a new release is available. RD6 is versatile and open thanks to the integration of the most common fieldbus interfaces: Profibus-DP, CANopen and Modbus RTU (RS-485). It is also equipped with a service serial interface for simplified configuration and set-up of the unit through the free software tool. RD6 rotary actuator is specifically designed to drive positioning and auxiliary axes and allows to dramatically cut machine set-up times and reduce downtimes, in particular in multi-axis systems. It is ideally suited for installation in mould changers, mobile stops, tool changers, filling and bottling machines, packaging lines, wood & metalworking machinery, paper machinery, printing & labelling machines, conveyors, suction cups motion units, spindle positioning devices.
