Epsilon EP-P Drive and FM-3/4 Module Reference Manual
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 FM-4 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.
Global Where Am I
PowerTools feature that indicates which line of which user program is executing.
Home Routine
The home provides motion in applications in which the axis must precisely align with some part of a machine.
Hysteresis
For a system with an analog input, the output tends to maintain its 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.
Index
An index is a complete motion sequence (defined motion profile) that moves the motor a specific incremental distance or to
an absolute position.
