6.12.4 Dynamic (regenerative) braking
: Dynamic braking selection
: Braking resistor operation rate
• Function
The VFS9 does not contain a braking resistor. Connect an external braking resistor in the following |
| ||
cases to enable dynamic braking: |
| ||
6 | |||
1) | when decelerating the motor abruptly or if overvoltage tripping (OP) occurs during deceleration | ||
| |||
| stop |
| |
|
| ||
2) | when a continuous regenerative status occurs during downward movement of a lift or the wind- |
| |
|
| ||
3) | when the load fluctuates and a continuous regenerative status results even during constant |
| |
| speed operation of a machine such as a press |
