Required Drive Features

Analog I/O

Each application has specific requirements for I/O. Analog I/O is generally used to read process signals and output signals proportional to drive status. Analog I/O is generally Voltage (0-10V) or Current (0(4)-20mA). The type and number required by the application must match the drive.
Requires: A drive with sufficient number and type of analog I/O.

Dynamic Brake

Applications that require rapid deceleration or quick stops can regenerate energy back to the drive. A dynamic brake dissipates this energy through a resistor as heat.
Requires: A drive that has an internal DB chopper and connectable resistor or has an external DB kit.

Dynamic Response

High performance applications often demand nearly instant response to changes in speed or torque commands or input status changes. The higher the dynamic response, the more capable the drive is in meeting these demands.
Requires: A drive that meets the response demands.

Fan / Pump Control

Many fan or pump installations have a wide spectrum of flow variations. These include water and sewage systems, process, and other industrial applications. Excellent flow control can be achieved by using a variable speed drive on one fan or pump and using the drive to control other units at fixed speed.
Requires: A drive with built-in Fan/Pump Control software.

Overload Torque

Applications may require varying degrees of overload capacity for starting, accelerating, or intermittent duty. This overload capacity must be supplied by the drive as current and by the motor as torque.
Requires: A drive that has sufficient overload capacity.

Power Loss Ride-Through

Applications that control a continuous process cannot afford to stop because of short power outages or dips. The process must continue to run through these outages, typically 2 to 3 cycles long.
Requires: A drive that has sufficient power loss ride-through capability.

Slip Compensation

A squirrel-cage motor slips under load. To compensate for this, the frequency can be increased as the motor torque increases.
Requires: A drive that provides adjustable slip compensation.

Speed Range (30:1)

All applications operate over a given speed range, defined as the ratio of maximum continuous speed to minimum continuous speed.
Requires: A drive that can produce the needed torque and speed torque regulation (accuracy) over the required speed range.

Motor Control Type

Sensorless Vector (SV)

Sensorless Vector is a motor control method that is often used to maximize torque production in the motor for loads that have significant overload requirements. It is NOT a torque control (regulation) method. This algorithm maintains a constant magnetizing (flux) current from zero to base motor speed. The output voltage is increased proportional to load. Automatic or manual tuning identifies key motor parameters including IR drop and nominal flux current, allowing automatic voltage boost at low speeds proper flux current maintenance.
Requires: A drive that offers this motor control method when torque production must be maximized.

Regulation Type

Torque

Applications that depend on accurate torque to accomplish the task require a drive that can control or 'regulate' torque. These applications typically control tension or force to produce a high quality product. The motor slip plus magnitude and phase angle of the output current are controlled to produce the commanded torque.
Requires: A drive that offers this motor control method when torque control is required.
