Omron G5 Lite low-cost servos

Based on the G5 series, the G5 Lite servos from Omron are a cut-down version, with a number of advanced features removed to reduce cost.

G5 Lite servos accept a single-phase 200 V source and output between 100 and 1500 W to a servomotor. Ready-made cables with moulded plugs are available for plug-and-play functionality. The matching servomotors have an optional holding brake, to maintain position when power is removed.

The motor’s in-built encoder resolution is 20 bit, equivalent to 1,048,576 PPR, and the drive accepts a pulse train input for direct replacement of stepper motors.

Both positioning and fixed value speed control modes are supported, along with eight inputs and three outputs, all with configurable functionality.

Optimum motor performance is achieved by the real-time autotuning facility, which can run continually. Vibration can also be significantly reduced by the enabling one of several adaptive or notch filters. Damping control is also provided and is suitable for keeping liquid loads level during movement to avoid spillage.
