checking the basic operations. Since the appropriate capacitance and resistance of the external
components vary depending on the motor type, they must be adjusted experimentally.
When FGC = 2.5 V, the internally-detected induced voltage is generated from the REV pin as a
square-wave signal. This signal is delayed by the amount of time specified by C

U-phase output

The difference between the zero-cross point of the induced voltage generated at the U-phase output
and the one of the induced voltage calculated by the TB6582FG should be measured by experiment
while the motor is operating in square-wave drive (120° commutation) mode. The C
should be specified corresponding to the measurement result.
When the motor is driven by the square wave (120° commutation), an input voltage of 2.5 V must
be applied to the FGC pin. When FGC = 2.5 V, the TB6582FG enters into Test mode and the REV
pin generates an induced voltage output of phase U calculated internally.
The motor should be operated with a rotation speed appropriate for the normal usage (, such as
700 rpm) in 120° commutation by applying an appropriate voltage to the V

enabled with a certain delay time. Though the automatic lead-angle correction is applied, the lead
angle can also be adjusted in the early stages. The range of the lead-angle correction is from 0° to
112.5° and the four-bit resolution (16 steps) can be programmed.
