Note 1: Determining the capacitor value of CLA
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 CLA capacitor value
should be specified corresponding to the measurement result.
< Determination Procedure >
(1)
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.
(2)
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 VSP pin.
(3)
Measure the difference (
YT) between the zero-cross points of the U-phase output and the REV
output.
(4)
The capacitor value of CLA should be determined according to the delay time (YT).

The external capacitor C2 considerably affects the factor that causes the delay time in the induced
voltage calculation. A capacitor of the same value as C2 should be connected to the CLA pin while
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 CLA.
Note 2: Since drive signals are generated by the calculated induced voltage, the outputs of those signals are
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.
