Operating Waveform When Driven by Square Wave
(CW/CCW

To stabilize the bootstrap voltage, the lower outputs (X, Y, and Z) are always turned on at the carrier cycle
even during off time. At that time, the upper outputs (U, V, and W) are assigned dead time and turned off
at the timing when the lower outputs are turned on. (T

e.

When the motor is driven by a square wave, acceleration or deceleration is determined by voltage V
e
. The
motor accelerates or decelerates according to the On duty of T
ONU.
(See the diagram for output On duty on
page 11.)
Note: The motor is driven by a square wave if REV = High, i.e., if the Hall signals at start-up are 5 Hz (fosc
=
4 MHz)
or lower and the motor is rotating in the reverse direction to that of the TB6551F/FG setting.
