Description

The Delta Tau 3U Digital PWM Amplifier board is a 3U-size amplifier designed to drive AC Induction, Permanent Magnet Brushless, DC Brushed type motors. This amplifier unit comes in two packages: Two 680W continuous power amplifiers or one 1360W continuous power amplifier. The 3U Digital PWM Amplifier may be interfaced conveniently to the PMAC controller via ACC-24E2 or ACC-8F. Typically, the amplifier is purchased with the Delta Tau 3U power supply and backplane interface card to distribute power to the unit.

The 3U Digital PWM Amplifier is a 3-phase direct PWM drive, utilizing the latest in smart power technology from the world’s leading vendors and the cutting edge algorithms of the PMAC2/UMAC controller family. The 3U Digital PWM Amplifier can drive all of the motor types commonly used in programmable motion control in both rotary and linear forms.

The 3U Digital PWM Amplifier is based on PWM (Pulse Width Modulation), a technique employing both frequency and phase to approximate sinusoidal currents and to control AC and DC motors.

Each axis of the 3U Digital PWM Amplifier uses a three H-bridge legs scheme. Each leg employs a top and bottom IGBT transistor. The motor windings are connected between the center points of top and bottom pairs. When two appropriate IGBT transistors in the bridge are turned on, the current flows through any two motor windings. Any two (top and bottom) bridge transistors are turned on by a logic from PMAC2 with no other conditioning necessary, except an optical isolation. The 3U Digital PWM Amplifier performs no control functions itself; it simply accepts direct PWM commands from the PMAC2. PMAC2 requires the position feedback and the feedback about the current fed to the motors to commutate each controlled axis.

The current feedback is provided in digital form as a part of a serial data stream of 18 bits (12 bits report the current feedback and remaining 6 bits report fault conditions) from the current feedback A/D converters which are located in the 3U Digital PWM Amplifier. Each axis has its own “mask” word that tells the PMAC2 how many bits to expect from the A/D converter. The clock and the strobe for the digital feedback are programmable at the PMAC2.

The position feedback is generally fed to PMAC2/UMAC via ACC 8F or ACC-24E2. The position feedback is not connected to the Quad Amp in any way.

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!
