TOSLINE-S20
Optical transmission device (Toshiba's product name). Exchanges operating
sequence signals and operation data with an external device equipped with this
transmission device.
Initialize
An initialization process.
In this equipment, as the control power is turned from off to on, the data and circuits
are initialized.
Interface
A method that exchanges signals between this equipment and external equipment.
Inverter
A reverse conversion circuit that converters DC main power voltage into AC voltage.
(DC
→
AC conversion)
Inverter unit
A box containing IGBT inverter circuit and gate drive circuit board.
Converter unit
A box containing the IGBT converter circuit and gate drive circuit board.
Overload
A status, in which the current output from this equipment, exceeds the continuous
rating of this equipment.
Converter
A conversion circuit that receives AC power and converts it to DC voltage (AC
→
DC
conversion).
A reversible converter also allows inverter operation but the converter connected on
the power supply side is called a converter.
