	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Mode of Operation
	Your choices are...
	Digital Position Feedback		Uses digital position feedback to control motor, in addition to speed sensors. A very common feedback device is a rotary encoder, with either incremental or absolute position signals. Position errors are calculated and compensated by the drive in real time. Use of feedback is referred to as "closed-loop control."
	Analog Feedback		An analog signal from a device such as a LVDT or potentiometer is used as the feedback for position; errors are quickly corrected by the drive. Analog feedback is typically a voltage signal, but may include frequency or DC current signals also.
	Velocity Mode		Direct feedback of motor speed is provided to the drive, and corrections are made with the motion control algorithm.
	Voltage (BEMF / Open Loop) Mode		No direct feedback from the motor via encoder, resolver, tachometer, or other device. The motor speed is inferred from the back EMF of the motor.
	Current (Torque) Mode		Current to the motor is sensed and fed back to the drive.
	Encoder Following / Slave		Can be run via feedback from another axis in a proportional or other defined way; descriptions include "encoder following," "electronic gearing," and "slave axis."
	Other		Other unlisted, specialized, or proprietary mode of operation.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Motor Feedback
	Your choices are...
	Hall Effect		Hall effect sensors detect the magnetic field induced by one or more rotating magnets on the motor rotor. The sensing of position or speed allows the drive to electronically commutate the motor at the correct sequence and timing.
	Resolver		Resolvers contain a rotating coil and two stationary coils 90° apart. By measuring the currents generated in the stationary coils through induction and comparing them, resolvers provide precise measurements of the rotor position. Resolvers depend on magnetic fields rather than electronics and thus work well in applications with high vibration, shock, and extreme temperatures.
	Tachometer		Tachometers sense rotational speed and provide the feedback to the drive for subsequent control signals.
	Incremental Encoder		Incremental encoders rely on multiple channels of position detection. A very typical configuration is two position signals 90° out of phase, or in quadrature, with an additional index or direction signal. Due to the limited number of signals, incremental encoders re-zero every time they are powered up. The most common technology is optical, with a glass disk with lines etched at precise angular increments providing position information.
	Absolute Encoder		Absolute encoders provide many signals concerning motor position, so many that it is possible to determine exactly the angular position at power-up. Like incremental encoders, there are different technologies, with optical being the most prevalent.
	Analog Position		Analog position signals include infinitely variable voltage signals from devices such as LVDTs, potentiometers, and other analog devices.
	Sine / Cosine		Sine / cosine feedback typically comes from optical encoders whose signals, in quadrature, have not been conditioned into square waves. Such signals have a theoretically infinite resolution; they may be practically limited by the electronics processing the signal.
	Other		Unlisted, specialized, or proprietary method of motor position or speed feedback.

	Features
	Your choices are...
	Soft Start		Control circuitry designed to allow the controlled motor to ramp up to full speed over time. This is often designed as a safety feature for motors moving large or fragile loads, and as a preventive measure for excessive current draw.
	Dynamic Braking		Method of motor braking in which the power supply is disconnected from the motor windings; the rotating motor then functionally become a generator whose power (heat) is dissipated through an often sizable resistor shunt across the windings. Also referred to as "rheostatic" or shunt resistor braking.
	Injection Braking		Applicable to AC motors only. The AC power is disconnected from the windings and a DC current is "injected" into the windings, creating a magnetic field opposing the motor rotation, thereby slowing and stopping the motor.
	Regenerative Braking		Method of motor braking somewhat similar to dynamic braking, in which the motor is disconnected from the power supply, and the power generated from the rotating motor is sent back to the supply. In some configurations, this generated power is used to recharge a battery that supplies the power to the drive.
	Brake Output		Relay or switch output designed to activate or control an external brake.
	Home / Limit Switch Input		Device has inputs for home and/or limit switches, indicating start, stop, or end-of-travel positions of the associated axes.
	Auxiliary I/O		Additional channels of input and/or output for communication with or feedback from the device.
	Alarm / Status Monitoring		Function in which one or more parameters are monitored for compliance with design operating parameters. In the case of a fault or non-compliant operation, an alarm or other signal can be generated to alert the operator or control system for appropriate action. Examples include overvoltage, overcurrent, and overspeed protection, temperature monitoring, and torque limiting interlocks.
	Self Configuration / Auto-tuning		The unit is designed to detect operating conditions and independently adjust its settings for for optimal system performance.
	Self Diagnostics		Device can intelligently detect fault conditions or other system problems and report the specific problem to the operator or control system.
	Electric Vehicle Design		Designed primarily for control of electric motors in industrial, recreational, or other electric vehicles. Many include application-specific features such as reverse alarm output, signal for speedometers and tachometers, etc.
	Other		Other unlisted or specialized features.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

PCI buses fully support cards that were developed for standard I/O buses. PCI extended (PCI-X) is an enhanced PCI bus that is backward compatible with existing PCI cards and features speeds up to 1 Gbps. PCI-X was designed by IBM, Hewlett Packard (HP), and Compaq to increase the performance of high bandwidth devices such as Gigabit Ethernet, Fibre Channel, and clustered processors. Versions of PCI-X include PCI-X 66, PCI-X 133, PCI-X 266 and PCI-X 533.

The STD 32 Bus provides a 32-bit wide data bus to support 8, 16, and 32-bit data transfers. Dynamic bus sizing, which varies the data path size depending on the requirements of the peripheral card being addressed, gives the STD 32 bus added flexibility.
	VMEbus		VersaModule Eurocard bus (VMEbus) is a popular, 32-bit bus used in industrial, commercial and military applications. The VMEbus is based on the VME standard, which defines mechanical specifications such as board dimensions, connector specifications and enclosure characteristics, as well as the electronic specifications for sub-bus structures, signal functions, timing, signal voltage levels, and master/slave configurations. The VMEbus uses 3U and 6U Eurocards, rugged circuit boards that provide a 96-pin plug instead of an edge connector for durability. Several VMEbus varieties are available.
	VXI / MXI		VME extensions for instrumentation (VXI) is an electrical and mechanical standard used mainly with automatic test equipment (ATE). VXI allows equipment from different vendors to work together in a common control and packaging environment.
