13. Reverse Rotation Brake
When the motor is rotating in reverse direction due to conditions like adverse wind, the direction of the
motor rotation is corrected to the regular direction (specified with the CW/CCW pin) using the reverse
rotation brake. The torque command for the brake control is specified by the VBRK input voltage. The
VBRK input voltage range is: 1.5 V < VBRK < Vrefout. However, when VBRK reaches 2.33 V (Duty cycle =
88%). The default setting for the VBRK input voltage should be 1.35 V (Duty cycle = 52%).
Timing Chart of the Reverse Rotation Brake Operation
If a reverse rotation of the motor is detected, the rotation direction is corrected to the regular direction by
rotating the motor in the opposite direction with a 120°-commutation signal.
The operation image of the drive outputs corresponding to detected voltages Eu, Ev and Ew is illustrated below.
Though TON’ varies according to the VBRK input,
TON ≠ TON’ due to the generated dead time TOFF.
