ABB ACS880-0500-3, Hardware Manual

Page: 11 / 88

The instructions and technical data which concern only certain optional selections are marked
with option codes (such as +E210). The options included in the drive can be identified from
the option codes visible on the type designation label.
Use of component designations
Some device names in the manual include the item designation in brackets, for example
[Q20], to make it possible to identify the components in the circuit diagrams of the drive.

Type of control board BCON
Type of control unit BCU
Control board for direct-on-line cooling fan BDFC
Internal power supply board in frame R8i modules BDPS
Control and power supply board for speed-controlled cooling fan BFPS
Conducts the surplus energy from the intermediate circuit of the drive to the brake
resistor when necessary. The chopper operates when the DC link voltage exceeds
a certain maximum limit. The voltage rise is typically caused by deceleration
(braking) of a high inertia motor. Brake chopper
Brake chopper enclosed in a metal frame or housing. Intended for cabinet installa-
tion. Brake chopper module
Dissipates the drive surplus braking energy conducted by the brake chopper to
heat Brake resistor
Brake chopper modules under control of one control board, and related accessories Brake unit
Circuit board in which the control program runs Control board
Control board built in a housing (often rail-mountable) Control unit
One section of a cabinet-installed drive. A cubicle is typically behind a door of its
own. Cubicle
DC circuit between rectifier and inverter DC link
Frequency converter for controlling AC motors Drive
Electromagnetic compatibility EMC
Physical size of the drive or power module Frame, frame size
DC circuit between rectifier and inverter Intermediate circuit
Drive for controlling several motors which are typically coupled to the same ma-
chinery. Includes one supply unit, and one or several inverter units. Multidrive
In the drive control program, user-adjustable operation instruction to the drive, or
signal measured or calculated by the drive.
In some (for example fieldbus) contexts, a value that can be accessed as an object,
eg, variable, constant, or signal. Parameter
Drive for controlling one motor Single drive
Type of memory unit, attached to the control unit ZMU
