2 - 4 ACV 700 Hardware Manual

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 (Hewlett-

Packard 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.
