ACS800-07 (+V992)

ACS800-07 (+V992) is a cabinet-mounted drive for controlling AC motors.

Cabinet line-up

The drive consists of several cubicles that contain the supply and motor terminals, 1 to 4 diode supply module(s), 2 to 6 inverter modules, and optional equipment. The actual arrangement of the cubicles vary from type to type and the selected options.

Swing-out frame

The swing-out frame inside the auxiliary control cubicle provides space for the inverter unit control board, control electronics of the drive, I/O terminal blocks, and optional electrical equipment. The lead-throughs for I/O cables, the auxiliary voltage transformer, and further space for additional equipment are available behind the frame. The frame can be opened by removing the two locking screws and moving the swing-out frame aside. (Depending on selected options, actual equipment of the drive may differ from what is depicted below.)

Control panel CDP 312R

A control panel (type CDP 312R) is installed on the door of the drive. The CDP 312R is the user interface of the supply unit and the inverter unit of the drive, providing the essential controls such as Start/Stop/Direction/Reset/Reference, and the parameter settings for the units’ control programs. More information on using the panel can be found in the Firmware Manual delivered with the drive.

The control panel is wired to both the supply unit and the inverter unit. www.abb-drive.com By default, the panel is set to control the inverter unit. The unit that is currently being controlled is indicated by the ID number. The ID number can be seen in the Drive Selection Mode of the panel. By default, one (1) denotes the inverter unit and two (2) denotes the supply unit.

The control panel can communicate with and control only one of the units at a time, and it displays the Warning and Fault messages of the unit it controls. In addition,the panel indicates the active warnings and faults in the unit that is not currently being controlled (for more information, see chapter Fault tracing).

Controls of the supply unit

The supply unit control program runs in the RDCU control unit located in the swing out frame. The RDCU is connected to the supply modules by a fibre optic link, and a separate wire set. If there are parallel supply modules, the controls from the RDCU are distributed to the modules with an optical branching unit (APBU board). The RDCU is also connected to the inverter unit with a fibre optic link and to the panel through the panel link.

Typically, the user controls the supply unit with the control devices mounted on the cabinet door. The use of these control devices is described in the following subsections. No additional control devices or connections are needed. However, it is also possible to control the unit with the control panel and through the fieldbus.

Main disconnecting device

The drive is always equipped with a main disconnecting device. The device is either the main switch-disconnector inside the module (no option +F253 or +F255), the main switch-disconnector outside the module (option +F253), or the main breaker outside the module (option +F255).

The user operates the main switch-disconnector(s) with a handle on the cabinet door. The breaker is withdrawable; its must be racked out when disconnection is needed.
