Can someone tell me why the motor doesn't change from lock to unlock? I designed a PCB circuit wich controlls the Motor movements and Lock. The motor has a magnetic lock. When switch to Unlock mode , the motor doesn't release the lock. it stays on lock . but when i disconnect the motor from the circuit it release the lock. can you please tell me what is wrong with the circuit.
even after I removed C203 and R221,then Q201-3 connected directly to the ground , still has the same issue. Thank you
