On stopping and starting, brake timing is crucial. If the brake is dis-engaged late, the drive will start with excess torque and will lurch forward. If the brake is dis-engaged before the drive has built up torque, the suspended load may fall. In some cases, the drive may not recover from a falling load.
Most new drives incorporate brake coordination. Several parameters including brake release and engage timing and the torque required when the brake is released must be entered. The turret or lifting table will not generally require formal torque proving and proving the condition of the brake with sensors. If a risk assessment determines that external torque proving is required, sensors can be wired to inputs on the drive.
