DC Braking Time
08 - 04 Momentary Power Loss Operation Selection
Factory Setting: 00
Settings | 00: Disabled |
| 01: Trace from top downward |
| 02: Trace from bottom upward |
This parameter determines the
The power system connects to AC drive may occurred momentary power loss by any probably reason. This function can make AC drive output voltage continuously after power loss and AC drive won’t stop by power loss.
If this parameter is set to 01, AC drive will trace from the last frequency before power loss downward. After output frequency of AC drive and running speed of the motor is synchronization, it will accelerate to master frequency command. It is recommended to use this setting if the motor loading has the characteristics of high inertial and low resistance.
If this parameter is set to 02, AC drive will trace from the Min. frequency upward. After output frequency of AC drive and running speed of the motor is synchronization, it will accelerate to master frequency command. It is recommended to use this setting if the motor loading has the characteristics of low inertial and high resistance.
08 - 05 Maximum Allowable Power Loss Time | Unit: 0.1 | |
Settings | 0.1~5.0 Sec | Factory Setting: 2.0 |

This parameter determines the maximum allowable power loss time. If the power loss time is less than the time defined by this parameter, the AC drive will execute
The allowable power loss time is beginning to count time after AC drive displays Lu. Therefore, actual allowable power loss time will change with loading.
