Problems related to AVT320 drive

I am using the AVT320 drive for EOT crain, so when i give +ve reference it works properly but while giving the -ve reference the motor would go +ve and after a few seconds it would go to the -ve side, what could be the problem

This could occur mostly in hoist drives and it’s normal, It is designed to develop a starting torque against free fall of the load when the brake is released & speed is 0. Provide breaking resistor & Set de-acceleration minimum time like 0.2 sec, not 0.0

Just check and adjust brake timing, I suggest delaying the brake release time
