15 Glossary

µs

Microsecond, which is 0.000001 seconds.

A

Amps.

Amplifier

Servo Drive.

ARMS

Amps Root Mean Squared (RMS).

Axis

The full system to control in a single motor shaft. A single SM-EZMotion module with Unidrive SP Drive can denote an axis.

AWG

American Wire Gauge.

Baud Rate

The number of binary bits transmitted per second on a serial communications link such as RS-232. (1 character is usually 10 bits.)

Check Box

In a dialog box, a check box is a small box that the user can turn “On” or “Off” with the mouse. When “On” it displays an X in a square; when “Off” the square is blank. Unlike option (radio) buttons, check boxes do not affect each other; any check box can be “On” or “Off” independently of all the others.

Complex Motion

A string of multiple motion commands and logical instructions that form a repeatable operation. For the SM-EZMotion module, the configuration file defines complex motion by setups, functional assignments and programs.

Compound Motion

The combination of indexes in a row in which the deceleration ramp of the first index goes to the velocity of the secondary index. The first index must be initiated within a program (Index.#.CompoundInitiate).

Configuration

The user-created application. It can be saved as a disk file or downloaded to configure the SM-EZMotion module. It includes all the user-defined setup, assignments and programs.

CRC

Cyclical Redundancy Check, the data transfer error checking mechanism.

Destination

A function (i.e., Stop, Preset) that may be assigned to an input line. In SM-EZMotion, the input function is connected to the action through click and drag operations in PowerTools Software on the Assignment View.

Dialog Box

A dialog box is a window that appears in order to collect information from the user. When the user has filled in the necessary information, the dialog box disappears.

DIN Rail

Deutsche Industrie Norm Rail

DLL

In Microsoft® Windows®, a Dynamic Link Library contains a library of machine-language procedures that can be linked to programs as needed at run time.

Downloading

The transfer of a complete set of parameters from an FM to a drive.

Drive

Servo drive or amplifier.

EEPROM

An EEPROM chip is an Electrically Erasable Programmable Read-Only Memory; that is, its contents can be both recorded and erased by electrical signals, but they do not go blank when power is removed.

EMC

Electromagnetic Compatibility. The relative immunity of a drive to the effects of electromagnetic fields.

EMI - Electro-Magnetic Interference

EMI is noise which, when coupled into sensitive electronic circuits, may cause problems.

Firmware

The term firmware refers to software (i.e., computer programs) that are stored in some fixed form, such as read-only memory (ROM).

Flash

Another type of EEPROM.

Flash File

In the SM-EZMotion module, this file loads the firmware into the drive and function module. Flash files can field upgrade the firmware.

FM

Function Module - device which is attached to the front of the drive to provide additional functionality.
