Fig. 1.8 - 1 CAN telegram with error frame

The Error Frame Counter switches, since one block of the CAN telegram (6 bits in this case) has

maintained the same state for approx.6μs. For a 1MBit bus, 1 bit has a length of 1μs, resulting in

a max. block length at the same level of 5μs.

The CAN Test Box Error Frame Counter is preset and counts 1 Mbit CAN bus at 5.5μs. 500KBaud

CAN bus HS60 is counted at 11μs.

These settings of 5.5μs and 11μs are factory set in the CAN Test Box with the help of a potenti-

ometer.
