What is the instruction on ATV71 IBR and BRT setting.
Brake release current (IBR); Adjust the brake release current to the rated current indicated on the motor. During testing, adjust the brake release current in order to hold the load smoothly.
=> If IBR is too high, it makes some torque oscillation during the BRT time, and this oscillation can be the root cause of load slipping.
Brake release time (brt): Set according to the type of brake. It is the time required for the mechanical brake to release.
