Precise speed control is crucial for reliable results.
Knowing speed is set and regulated, within a tolerance of +0.1 RPM for extended periods of time, assures consistent results. Using a Luminary drive, speed of the motor shaft is measured on a periodic time-base and compared to the input target value. Any difference is applied as a correction to the torque control that is needed to accelerate or decelerate the motor shaft back to the desired speed.

Precision Speed Control

Drive interface bypasses normal analog circuit path to allow access to digital registers which control operation of speed control loop.

Shaft speed stays constant within a small tolerance due to the quick reaction time of the correction applied to the torque control loop.

Consistent results ideal for liquid mixing or pumping.

Luminary Motion Controller

Luminary series also includes multi-axis capability to control four Luminary Series drives and access up to 36 I/O points.
