WESTWOOD, MASS. The pre-engineered drive package from Copley Controls, the Model 5224AC servoamp and a factory-matched NEMA size 23 servomotor, reduces engineering time-to-market for robotics applications. The drive package plugs directly into a 120-Vac wall outlet.
The servoamp, measuring 7.5 by 2.72 by 7 inches and weighing 3.71 pounds, drives Hall-commutated dc brushless servomotors to 1.25 horsepower. The amplifier develops plus/minus 10-amp continuous output and plus/minus 20-A peak for motors rated to 130 V. The servoamp's built-in power supply, which provides high-voltage dc for motor drive, also delivers an isolated 5 Vdc at 200 mA and plus/minus 10 V at 5 mA for shaft encoder and Hall sensor excitation. Optoisolators ensure electrical safety, providing a link between the ground-based control and feedback circuits and the high-voltage motor-drive circuits. These amps can operate in either torque or velocity modes.
They are protected against overcurrent, overtemperature, and incorrect operating voltages, as well as short circuits between outputs and from output to ground.
Users have a choice of two motors, both of which run at 6,000 rpm. The CBL232BE delivers 82 ounce-inches of rated torque and 477 ounce-inches peak torque. The CBL233BE develops 114 ounce-inches rated torque and 685 ounce-inches peak torque. The motors are equipped with Hall sensors for motor commutation and for creating velocity feedback signals. Each motor's built-in 1,000-line shaft encoder enables an associated controller to develop position and speed-control commands. Used with the servoamp's built-in frequency-to-voltage converter, the motor's encoder signals also yield velocity feedback for tight speed control.
The package is priced at $1,095 in hundreds for the 5224AC servoamp and CBL232BE or $1,121 for the servoamp and the CBL233BE. Delivery is stock to 4 weeks .
