The transfer of a complete set of parameters from PowerTools or an FM-P.
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
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).
FM
Function Module - device which is attached to the front of the drive to provide additional
functionality.
Hysteresis
For a system with an analog input, the output tends to maintain it's current value until the
input level changes past the point that set the current output value. The difference in response
of a system to an increasing input signal versus a decreasing input signal.
I/O
Input/Output. The reception and transmission of information between control devices. In
modern control systems, I/O has two distinct forms: switches, relays, etc., which are in either
an on or off state, or analog signals that are continuous in nature generally depicting values
for speed, temperature, flow, etc.
Inertia
The property of an object to resist changes in rotary velocity unless acted upon by an outside
force. Higher inertia objects require larger torque to accelerate and decelerate. Inertia is
dependent upon the mass and shape of the object.
Input Function
A function (i.e., Stop, Preset) that may be attached to an input line.
