250 ns for digital signals, and 2
μ
s for analog signals. Grounds are
separated by the optocouplers’ galvanic isolation barrier.
Both input and output connections are made via 40-pin ribbon cable
connectors. The pin assignments for both connectors are the same. For
example, signal PWM_AT appears on pin 1 of the input connector and
also on pin 1 of the output connector. In addition to the usual motor
control signals, an MC68HC705JJ7CDW serves as a serial link, which
allows controller software to identify the power board.
Power requirements for controller side circuitry are met with a single
external 12-Vdc power supply. Power for power stage side circuitry is
supplied from the power stage through the 40-pin output connector.
The electrical characteristics in
Table 3-3
apply to operation at 25
°
C,
and a 12-Vdc power supply voltage.
