Undervoltage Stall Level

Program Protection
This parameter sets the low end of the DC bus voltage threshold that, once it
drops below this setting, will activate the Ridethrough feature, if enabled.
Activation may be the result of a momentary power loss or an excessive load on
the bus voltage. Once activated, the system will attempt to maintain the bus
voltage level set here until the motor stops.
Note: This feature may decrease deceleration times.

Undervoltage Time

Program Protection
This parameter sets the time that the undervoltage condition must exist to cause
an Undervoltage Trip when this function is enabled at the Undervoltage Trip
parameter.

Undervoltage Trip

Program Protection
This parameter Enables/Disables the Undervoltage Trip function.
With this parameter Enabled, the ASD will trip if the undervoltage condition
persists for a time greater than the Undervoltage Time setting.
A user-selected contact may be actuated if so configured.
If Disabled the ASD will stop and not trip; the FL contact is not active.
