Program features 79
The following table shows the values of selected DC voltage levels. The drive DC
voltage limits are calculated based on the parameter 95.01 Supply voltage and 95.02
Adaptive voltage limits.
Notes:
• parameter 95.03 Estimated AC supply voltage is the estimated voltage during
start-up of the drive and is not continuously updated during the time lim eit.
• The absolute voltages vary according to the drive/inverter type and AC supply
voltage range.
