PD

Phase comparator output

The phase error is converted to a pulse duty and

output from this pin.

9

EI

Error amplifier input

10

EO

Error amplifier output

11

TOC

Torque command input

This pin is normally connected to the EO pin.

When the TOC voltage falls, the UH, VH, and WH on

duty is increased.

12
