Newport C-Drive is a series of versatile general-purpose power amplifiers optimised to enable third party motion controllers drive Newport motorised stages and actuators.
Newport C-Drive is a series of versatile general-purpose power amplifiers optimised to enable third party motion controllers drive Newport motorised stages and actuators.
+/-10V analogue command input signals are required for DC motor control, and pulse and direction commands are required for stepper motor control.
The new amplifiers are highly recommended for controllers featuring custom application software or special functions which Newport motion controllers do not carry.
The C-Drive series comprises a DC brush servo amplifier (CDR-DCB) and a stepper motor amplifier (CDR-STEP), which both operate from +48V DC power supplies.
The CDR-DCB can be set to either torque (current) or speed (voltage) mode and can be easily used with digital controllers that calculate position and velocity from the motor's encoder.
The CDR-STEP driver can micro-step precisely up to 250x and reduce power at end of motion automatically to reduce stage heating.
C-drive amplifiers can drive Newport's positioners with motors up to 4A and are easily user-configurable (software included) via RS232 serial interface.
MOSFET output stages deliver four-quadrant power for bidirectional acceleration and deceleration of motors.
For added convenience and fast prototyping, Newport offers a full set of complementary accessories such as cables, power supplies, and a cable break-out-box for easy interfacing with our ESP6000 motion controller.
All models are also protected against output short circuit and baseplate overtemperature.
