6KCV301DGF
1.2 HARDWARE DESCRIPTION
The power supply is external to the card and comes directly from the drive.
The DGF is defined as the option 2 card in the drive
A module with DNet interface can be mounted on the 6KCV301DGF card, if desired.
The main 6KCV301DGF hardware characteristics are:
-
Intel “embedded” 80386EX 25MHz microprocessor
- Numerical processor 80387 SX 25MHz
- Two static RAM memories (128Kword)
- A FLASH-EPROM boot block memory (256Kword)
- 2 Kbytes serial EEPROM
- VPP signal 12V circuit generator for flash clear/programming
- Microprocessor supervisory circuit for supply surveillance and reset generation
- Serial link RS-485 with SLINK3 protocol.
- 2 Kbytes DPRAM (Dual Port Ram)
- CPU OK (Hardware Watchdog)
- Led for PWR, RST,VPP,CPU OK, CAN and status
The following picture shows the connections between 6KCV301DGF card and the

1.2.1 MEMORY MAP
The RAM address must start at 0:0 because the vector interrupts area is in the lowest
address. The flash EPROM must be mapped on the top area because the reset address
is FFFF:0. The DPRAM is mapped at the end address of RAM area.
