2.2 Drive Options
The ESP302 controller is capable of driving up to 3 axes of most Newport positioners
using driver cards. These factory-tested drives are powered by an internal 200 W power
supply with 150 W for motion and 50 W for controller.
When used with Newport ESP stages, the configuration of the driver cards is easy using
the auto-configuration utility software.
The motor drive has the capability to drive bipolar stepper motors in microstep mode
(sine/cosine commutation)
The motor drive has been optimized for use with high-performance DC motors. It is
capable of driving DC motors in voltage mode and in current mode. All parameters are
programmable in physical units. Furthermore, the motor drive features individual limits
for the RMS current and the peak current.
