Note : The “H” state for FR is defined as a voltage of 8V or higher, and the

“L” state for FR is defined as a voltage of 4V or lower.

(When VCC = 12V.)

Note : For the Hall inputs, the input high state is defined to be the state

where the (+) input is higher than the corresponding (-) input by

0.01V or higher, and the input low state is defined to be the state

where the (+) input is lower than the corresponding (-) input by

0.01V or higher.

Note : Since this drive technique is a 180° current application scheme, the

phases other than the sink and the source phases will not turn off.
