Description
Voltage/current measurement unit
Type of a control unit
L-filter. BDCL-14 and BDCL-15 filters are used with DC/DC converters.
Circuit board in which the control program runs
Control board built in a rail-mountable housing
One section of a cabinet-installed drive. A cubicle is typically behind a door of
its own.
DC/DC converter charges or discharges an energy storage (such as a battery
or capacitors) in the DC bus.
ACS880-104 R8i used as DC/DC converter module
DC/DC converter unit consists of
module.
DC/DC converter unit
Digital input
Direct-on-line fan (option +C188)
Frequency converter for controlling AC motors
Device that stores electrical energy, for example, a battery or a super capacitor.
Refers to power modules that share a similar mechanical construction, for
example:
• DC/DC modules of frame R8i
• frame 2×R8i includes two size R8i DC/DC modules.
To determine the frame size of a component, refer to the
tables in chapter Technical
Inverter unit
Converts direct current and voltage to alternating current and voltage.
Inverter module(s) under control of one control board, and related components.
One inverter unit typically controls one motor.
Input/Output
Drive for controlling several motors which are typically coupled to the same
machinery. Includes one supply unit, and one or several inverter units.
In the control program, user-adjustable operation instruction to the drive, or
signal measured or calculated by the drive
Programmable logic controller
Drive for controlling one motor
Part of the drive system that rectifies the AC supply voltage and outputs a DC
voltage.
Uninterruptible power supply
