100%. That is, the use time of the braking unit is fixed to 100.0s
Action voltage of braking unit can be selected by adjusting PA.11. The motor can be stopped rapidly by
energy braking with the appropriate action voltage.
Note: Set PA.09 to 1 when using braking unit. For model selection of braking unit parts and connection,
refer to 1.9 braking unit model selection.
Generally, when inverter produces a failure alarm, the relay will make corresponding indication action.
With this function, the action of error relay terminal can be set under some special conditions.

Failure locked
0: Disable; 1: Enable
Unit place: Under low-voltage status such as power-up or power failure, choose whether the failure
indication to act or not.
Tens place: When the real failure is not displayed during auto reset period, choose whether the failure
indication to act or not. Refer to PA.21 and PA.22 instructions.
Hundreds place: If failures lock function enabled, when locked failures during last power-failure are
displayed after power-on again, choose whether the failure indication to act or not. Refer to PA.20
instruction.
Overload prealarm function can realize indication of pre-setting overload status or alarm stop.
PA.13 determines overload prealarm detection volume and conditions.
