Changing and stopping revolutions
(1) The motor speed or revolutions can be changed by adjusting the VDUTY voltage (TB6520P/PG input
voltage).
(2) To stop the motor, drop VDUTY to 0 V.
About steppingout
Monitor the TB6520P/PG’s speed detection signal (FG output) to see if a FG signal of the designated frequency
is returned. If not, the motor has stepped out of synchronization, so restart it.
About overcurrent limiting operation
The TA8483CP’s overcurrent detection function works in such a way that the motor current is detected using
an external resistor and when the voltage that develops in the resistor exceeds the reference voltage VRF, the
ISD signal is driven high. The TB6520P/PG limits the ONtime of the PWM signal (output by the
TB6520P/PG) at a rising edge of the ISD signal. The ONtime of the upperside power transistor in the
TA8483CP is thereby limited.
Lead angle control
The TB6520P/PG determines the commutation timing based on the changeover point (zerocross point) of the
induced voltage and reference voltage Vn (= VM (motor’s power supply voltage) divided by 2).
During forced starting commutation, the motor operates with a lead angle of 0 degrees. After the motor
switches over to normalspeed operation, the lead angle is automatically changes to 15 degrees.
(Lead angle of 0 degrees : For 120degree switchon, current starts conducting 30 degrees behind the
zerocross point. Lead angle of 15 degrees : Current starts conducting 15 degrees behind the zerocross point.)
Note that depending on motor characteristics, the waveform of the induced voltage may be distorted, causing
the zerocross point to slip out of place. The commutation timing also is thereby made to drift.
