Attribute Description
Undervoltage Start Delay is a delay to prevent this protection, if enabled,
UINT16 RW NV
from tripping the motor at start up until this time expires. If the
Default: 20
Undervoltage condition is still present after this time delay, then a trip
Range: 0 to 60
would occur following the Undervoltage Trip Delay Time.
