PC

Personal Computer.

PE

Protective Earth.

PID

Proportional-Integral-Derivative. An acronym that describes the compensation structure that can be used in many closed-loop systems.

PLC

Programmable Logic Controller. Also known as a programmable controller, these devices are used for machine control and sequencing.

PowerTools Pro

PowerTools Pro is a Windows® based software to interface with the SM-EZMotion module.

Commonly refers to Read-Write memory, as opposed to Read-Only Memory (ROM, EPROM, EEPROM, Flash). RAM is considered volatile, because its contents are lost during a power loss.

RMS

Root Mean Squared. For an intermittent duty cycle application, the RMS is equal to the value of steady state current which would produce the equivalent heating over a long period of time.

ROM

ROM is an acronym for Read-Only Memory. A ROM contains computer instructions that do not need to be changed, such as permanent parts of the operating system.

RPM

Revolutions Per Minute.

Serial Port

A digital data communications port configured with a minimum number of signal lines. This is achieved by passing binary information signals as a time series of 1’s and Ø’s on a single line.

Source

The terminals at which energy is taken from a circuit or device.

Travel Limit

The distance that is limited by either a travel limit switch or the software.

Torque

The moment of force, a measure of its tendency to produce torsion and rotation about an axis.

Uploading

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

User Units

Ability of program to allow user to specify which type of units will measure and specify motion and time.

VAC

Volts, Alternating Current.

Variable

A labeled value that encompasses numeric boolean, input function, and output functions.

VDC

Volts, Direct Current.

Velocity

The rate of change in position in a given direction during a certain time interval.

View
