Fig. 7-22 Example of incorrect parameterization
If parameter p1532 cannot be sensibly parameterized for all situations where the
brake test is to be carried-out, then the automatic determination of the load torque
must be activated using MA_SAFE_BRAKETEST_CONTROL.
Commissioning
To support the commissioning of the brake test Alarm 20096, "Axis %1 brake test
aborted, additional info %2" can be enabled using bit 5 in machine data $MN_ENA-
BLE_ALARM_MASK. This alarm supplies detailed information if the brake test is
interrupted.
