Operating Waveform When Driven by Square Wave
(CW/CCW
=
LOW, OS
=
HIGH)
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
d
varies with input V
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 of output ON duty on
page 14.)
Note: At startup, the motor is driven by a square wave when the Hall signals are 5 Hz or lower (f
osc
=
4 MHz) and
the motor is rotating in the reverse direction to that of the TB6556F/FG controlling it (REV
=
HIGH).
