Note:
P1256 = 0:
Maintain DC-link voltage until mains is returned or converter is tripped with undervoltage. The frequency is
kept above the frequency limit provided in P1257.
P1256 = 1:
Maintain DC-link voltage until mains is returned or converter is tripped with undervoltage or pulses are disa-
bled when frequency falls below the limit in P1257.
P1256 = 2:
This option ramps down the frequency to standstill even when mains return.
If mains do not return, frequency brought down under the control of Vdc_min controller until P1257 limit.
Then pulses are disabled or undervoltage has occurred. If mains return, then an OFF1 is active until P1257
limit. Then pulses are disabled.
