Reverse Rotation Detector H1+ + H1- - H2+ + H2- - CK EC ++ ECR - FR Case 1] Forward Rotation ( EC＜ECR ) Hall input H1+ and H2+ have phase relation as shown Reverse Rotation Detector circuit. In this case, reverse detection don’t operate. Case 2] Reverse Rotation ( EC＞ECR ) Hall input H1+ and H2+ have opposite relation to forward rotation. So detective circuit operate, make output open. Actual motor rotation at reverse detection Forward Rotation at EC＜ ECR ↓ Rotating speed is decreased due to reverse torque at EC ＞ECR ↓ When motor starts to reverse, reverse detection operates and output become open ↓ Rotating reverse at short time due to inertia ↓ Stop KSD-I7A005-001 SEPT., 2010 REV. 01 10 S3313 6.
