DRV8701: Motor drivers forum

hello team,my DC motor driver  can drive and the functions(forward,backwards,slow,fast) are well but if I put a small load on it(improve the current slowly)it can run on 3A+ current but if I give it full pwm and hold  the motor,the motor doesn`t have force (if I let it go it could keep going)  i didn`t  open the OCP  this is my schematic .thank you !
