Historic log
The historic log is a troubleshooting/diagnostic tool of the control. The historic log continuously
logs drive status, including the drive state, internal fault words, and multiple user-selectable
variables. This information is sampled every slow loop cycle of the control (typically 450 to 900
times per second). If a fault occurs, the log is frozen a predefined number of samples after the
fault event, and data samples prior to and after the fault condition are recorded to allow post-
fault analysis. The number of samples recorded are user-selectable via the control, as well as
the option to record the historic log within the VFD event log.
Host Simulator
see Tool Suite definition.
I/O
I/O is an acronym for input/output. I/O refers to any and all inputs and outputs connected to a
computer system. Both inputs and outputs can be classified as analog (e.g., input power, drive
output, meter outputs, etc.) or digital (e.g., contact closures or switch inputs, relay outputs,
etc.).
IGBT
IGBT is an acronym for Insulated Gate Bipolar Transistors. IGBTs are semiconductors that
are used in the drive to provide reliable, high-speed switching, high-power capabilities,
improved control accuracy, and reduced motor noise.
Induction motor
An induction motor is an AC motor that produces torque by the reaction between a varying
magnetic field (generated in the stator) and the current induced in the coils of the rotor.
Intel hex
Intel hex refers to a file format in which records consist of ASCII format hexadecimal (base 16)
numbers with load address information and error checking embedded.
Inverter
The inverter is a portion of the drive that changes DC voltage into AC voltage. The term
"inverter" is sometimes used mistakenly to refer to the entire drive (the converter, DC link, and
inverter sections).
Jog mode
Jog mode is an operational mode that uses a pre-programmed jog speed when a digital input
(programmed as the jog mode input) is closed.
