101 MAINS LOSS Loss of AC supply

: Regen rectifier trip, signalled by
the serial link to the Regen inverter (see
11.66
).

synchronisation with the mains.

Adjustment range: Disabled (0) or Enabled (1)
Factory setting: Disabled (1)
Format: 8 bits
When this function is enabled, the drive harnesses the potential
energy that may be stored in some very specific load types (eg:
Progressive Cavity Pumps), to extend the possible operating
time without the mains. Depending on the system status when
the mains supply disappears, the drive can therefore operate
for a few minutes rather than a few seconds with just the load’s
kinetic energy.
If the mains supply returns before the time set in
06.62
(adjustable up to 320 seconds, or more than 5 minutes), the
drive reaccelerates the motor up to the reference speed.
Otherwise, a mains loss trip is generated.
