If parameter 95.01 Supply voltage is set to Automatic / not selected and 95.02 Adaptive voltage limits
is set to Enable , the value of parameter 95.03 Estimated AC supply voltage is used,
2)
otherwise the
lower limit of the range selected with parameter 95.01 Supply voltage is used.
3)
The drive trips on the undervoltage fault when parameter 21.18 ( Auto restart time ) elapses or the value
of parameter 21.18 is 0. In that case the standby limit is used as the undervoltage trip level. The
undervoltage fault occurs only if the drive is modulating when the DC voltage drops below the
undervoltage trip level.
