(A) When the output is sourcing current
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 V
V
88%). The default setting for the VBRK input voltage should be 1.35 V (Duty cycle = 52%).
If a reverse rotation of the motor is detected, the rotation direction is corrected to the regular direction by
