How to set the brake logic noting that SCF1 fault (Output short circuit) appears on ATV61?
If you have SCF1 for ATV61/71 & the brake logic is not correctly set-up, Kindly perform the following:
- With the Brake Logic configured, increase the starting time between the end of closing sequence & the beginning of opening the brake.
- Adjust the parameter ttr [Menu brake logic] to 3 times the rotor time constant measured by the autotuning [expert mode & reading of T2r in the menu drC].
- Adjust the brake logic as described in the programming guide [menu Fun].
- If the motor is saturated, decrease the leakage inductance measured by the autotuning by 5% [expert mode & reading of Lfr in the menu drC].
