ABB ACV 700 Frequency Converters

Chapter 1 - System Description

This manual describes the ACV 700 drive system to the application engineers and other persons involved with ACV 700. The drive has a multidrive configuration. It consists of a supply section including connection devices (main fuses and main contactor or circuit breaker), rectifier devices (a diode or thyristor bridge), capacitors for smoothing of the DC voltage, optional devices, if specified, and a number of drive sections. The power range for the supply sections is 40 - 2500 kVA and the power range for the drive sections is 9 - 2500 kVA. Depending on the required power and voltage, the drive sections are based on either an IGBT or GTO thyristor power stage. The control system is implemented by using the Common Drive Control, CDC, and the Digital Drive Control, DDC. The basic part of the CDC is the Application Controller, the APC. The APC is designed to give a flexible, compact and efficient system for controlling AC or DC drives. The APC is programmable by using function blocks. The DDC performs the inverter control functions. Programming can be done using two alternative tools, the Function Chart Editor, FCE or the AdvaBuild for Windows, the Drives version. Various drive configurations are possible using one or multiple APCs and their communication capabilities. In small systems one APC is connected to up to four Digital Drive Controllers (DDC). The drive configuration can be used in master/ follower applications when the master drive is of moderate complexity and the followers fairly simple. A consequence of multiplexing is that the performance of the drive controller interface decreases.

System Description

Figure 1 - 1 Small drive system. In distributed multicontroller systems, several

 APCs are interconnected by Advant Fieldbus 100 (AF100). Common control

 functions can be distributed to separate nodes. No overriding automation

 system is used in this configuration, but one or several application controllers

 can communicate with external systems over communication boards. A personal

 computer (PC) can be connected through one of the APCs and can be used for tool functions.

The concept of the control system is called Common Drive Control, CDC. The standard control functions of the drive section, such as speed and torque control, are located in the Digital Drive Controller, DDC. The application dependent control functions are located in the Application Controller, APC. Typical APC functions are section start and stop logic, internal and external interlocking, speed reference chain, load share control, drive-specific settings, logger functions, and system communication. Function blocks can be combined to macro blocks, which can perform application specific tasks such as crane control, lever control, remote panel control, etc. Each APC can control up to four DDCs. The APC is usually located in the drive section. The APC communicates with other APCs and with the centralised operator control devices via the AF100 communication bus. The APC and the DDC communicate via an optic fibre link. If the solution includes more than one DDC, an optic distributor board is

APC is designed to give a flexible, compact and efficient system for controlling AC- and DC-drives. APC is programmed by using function blocks. APC can be supplied with unstable + 24 VDC voltage (connector X1) that can vary in the range 19 - 30 VDC. Maximum input power consumption is 15 VA (0.63 A at 24 VDC). This power consumption includes 2 optional communication boards. APC can handle power supply failure with max. duration of 5 ms (i.e. voltage is below 19 V). When the APC board is slid into the CDC board rack, a 64 pole parallel bus (connector X8) on APC slides into the CDC board rack bus connector. AdvantFieldBus 100 (AF 100) is a high speed serial bus (connector X6), which is used for communication between APCs or between an APC and an overriding system such as ABB's MasterPiece 90. The communication board YPK 112A is used to connect the APC to the AF 100. RS-485 bus, a 8 pole screw terminal connector X2, is a low speed serial bus, which is used to connect remote I/O devices and control panels to the APC. Also other APCs can be connected to each other via this bus. The bus has to be grounded at one point to the same ground as the APC. Maximum length of the bus is 300 m. PC-Link, a standard 9 pole female D-connector X4, can be used to connect a personal computer to the APC. Physical interface is a standard non isolated RS-232C (V24) without any handshaking signals. Recommended maximum length of the cable between APC and PC is 5 m. Drive link, an optic link, is used to connect the APC to an AC or a DC drive. Optical fibres are connected to receiver V32 and transmitter V33. Communication speed is 1.5 Mbps. Max. length of the fibre is 15 m with standard attenuation cable (Hewlett-Packard HFBR-R or equivalent) and 25 m with extra low attenuation cable (HewlettPackard HFBR-E or equivalent). For standard I/O signals there is a 26-pole ribbon cable, connector X3, on APC. A separate terminal block board SNAT 602 TAC is always needed for field signal connections. The ribbon cable should be made as short as possible. Unshielded ribbon cable can be used provided that the cable is not longer than 2 m.

Jumper settings on SNAT 602 TAC: The jumper settings have no effect when the terminal block board is used with the APC.

The control panel provides the following information and functions: - Status information (run, ready, fault messages)

 - Operational control with 4 freely programmable pushbuttons - Display of reference values (speed, torque) - Display 

of actual values (speed, voltage, current) - Display of fault logger contents - Uploading, downloading, changing, displaying

 and saving the APC and DDC parameters. It can be used to control up to four DDCs one by one, depending on the application

 program. Panel functions are freely programmable. The 9 VDC external power is supplied by the door panel Power Supply Board

 APC 700 PPW. Dimensions of the panel are (w x h x d) 125 x 120 x 20 mm. Code: 3AFE 61064770 The door panel power supply

 board is used to create the 9 VDC auxiliary voltage needed for the APC 700 PAN. The board is connected directly to the door panel

 phone jack type connector by means of a male/male connecting piece. The board needs external 24 VDC power supply. Max. 

current is 200 mA. A shielded signal cable from the APC is connected to connector X1. If the solution has several door panels

with one APC, the signal cable can be distributed from connector X1 to connector X1 on the next power supply board. The

The board is a general purpose I/O-board for connecting field signals to APC. It can be used as an extended or remote I/O-board.

 The terminal board is always needed with the board because connection to the board is made with a ribbon cable. When the boa

rd is used as an extended I/O-board, it is slid into the CDC board rack and a 64-pole parallel bus connector X1 on the YPQ 111A s

lides into the CDC board rack bus connector. APC board is connected in the same way with the connector X8 to the parallel bus. Th

e 24 VDC power supply for the board is delivered by the parallel bus flat cable. Power consumption is 5 VA (0.2 A at 24 VDC). Peak

 current with starting condition is 4 A. When the board is used as a remote I/O-board, it can be mounted anywhere and it is connec

ted to the YPP 110A via the low speed serial bus (RS-485). This configuration needs an external 24 VDC power supply and it is pow

ered via the connection card. Although the address for the board can be set to 0 - F (hex) with switch S1, the system software use

s only addresses 1 - 4 (hex) for the extended I/O-board. Because of this, only 4 extended I/O-boards can be connected to one APC.

 Field signals can be connected to the YPQ 111A board via the YPT 111A or YPT 111B connection card. If no extra qualities for input

s and outputs are needeed, YPQ 111A can be used with the connection card UT86-2X40C

The Extended I/O Terminal Board YPT111A is used together with the Extended I/O Board YPQ111A. The Extended I/O Terminal YPT111A is connected to the Extended I/O Board YPQ111A with two 40-pin flat cables. Connection card YPT 111A is used for connecting the field instruments to YPQ111A. There are two separated power supply inputs for 24 VDC in the I/O terminal board YPT111A: +24V IN / BI for binary inputs (X1: pins 1,3,5,7) and +24V IN for YPQ111A when it is used as remote I/O (X1: pins 9,11,13,15). For chaining these voltage inputs from one YPT111A to another YPT111A or YPT111B there are 4 inputs for both the supplies. In the case of chaining one to three 24 VDC inputs will be used as outputs. Pins 9, 11, 13 and 15 of connector X1 should never be used if the I/O board YPQ111A is used as local I/O. The YPQ111A is then connected to the Application Controller YPP110A via the parallel back plane I/O connector and not via the serial bus
