  • (3) LEDs for faster setup: Normal/Enable, Power-OK, Fault (Short or Overtemp)


The Copley Controls Corp 400 Series DC Brush Servo Amplifiers are third-generation amplifiers for DC brush motors from Copley Controls Corp. Models operate from +24 to +225VDC unregulated power supplies, and output peak currents from 10 to 30A. Built using surface-mount technology, these amplifiers offer a full complement of features for servo motor control. All models take industry standard ±10V control signals as input, and operate motors in three different modes: torque, velocity, and voltage feedback with IR compensation.

Torque-mode finds the widest application for motors used with digital control cards that take encoder feedback from the motor for velocity and position control. Velocity loops using brush-tachometer feedback are used for open-loop speed controls, or in position control loops requiring superior regulation at low speeds. Tachless speed controls can be made using output voltage feedback with IR compensation where lowest cost is required.

Active logic-level of /Enable, /Pos Enable, and /Neg Enable inputs is switch-selectable to interface with all types of control cards. Ground-to-enable or ground-to-inhibit are both supported. Mosfet H-bridge output stage delivers power in four-quadrants for bi-directional acceleration and deceleration of motors. An internal 40-pin header socket holds components that configure the various gain and current limit settings to customize the amplifiers for a wide range of loads and applications.

Individual peak and continuous current limits allow high acceleration without sacrificing protection against continuous overloads. Peak current time limit is settable to match amplifier to motor thermal or commutation limits. Header components permit compensation over a wide range of load inductances to maximize bandwidth with different motors.

All models are protected against output short circuits ( output to output and output to ground ) and heatplate overtemperature. With the /Reset input open, output shorts or heatplate over temperature will latch off the amplifier until power is cycled off and on, or until the /Reset input is grounded. For self-reset from such conditions, wire /Reset to ground and the amplifier will reset every 50ms. Three status LEDs speed diagnostics during set-up, or for fault isolation after the unit is in service.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
