The Copley Controls Corp 7225AC and 7425AC models are PWM servoamplifiers for AC brushless servomotors that are commutated externally by digital control systems that output two +/-10V signals that represent the current command to the motor U and V windings. The amplifier then synthesizes the current command for the W winding.Control cards take feedback from an encoder on the motor and use various techniques to determine the rotor position. Then the controller is able to output two signals that correspond to the current in the U and V windings to produce torque in the motor. The amplifier synthesizes the W winding current from UV signals that are either 120 or 90 electrical degrees apart.Amplifier adjustments with this system consist of inductance compensation, current limit, transconductance, and offset. Thereafter, the controller does all of the velocity and/or position control of the motor.An internal 40-pin solderless socket lets the user configure the various gain and current limit settings to customize the amplifiers for a wide range of loads and applications.

Header components permit compensation over a wide range of load inductance's to maximize bandwidth with different motors.Current limiting is provided via an internal solderless header socket or by an external resistance or voltage applied to the signal connector. The /Enable input active logic-level is switch-selectable to ground or +5V to interface with all types of control cards. Fail-safe operation in either polarity results from an internal jumper that selects the default input level and input resistor pull-up or pull-down connections so that the amplifier shuts down with no input. 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!
