2-16 AC Brake, Max current
Default value: 100%
Parameter type: Range
2-setup: All setups
Conversion index: -
Data type: u_int16
Change during operation: True
Enter the maximum permissible current when using the AC brake to avoid overheating motor windings.
Table 94: Range:
Min: 0%
Max: 160%
Default value: 100%
2-17 Over-voltage Control
Default value: [2] Enabled
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: True
Select whether to enable OVC during ramp down, which reduces the risk of drive trip due to overvoltage on the DC link caused by
generative power from load.
Table 95: Option:
[0]
Disabled
No OVC required.
[1]
Enabled (not at stop)
Activates OVC when the drive is not in the stop state.
[2]
Enabled
Activates OVC.
N O T I C E
The ramp time is automatically adjusted to avoid tripping of the drive.
