When momentary power loss is detected, the b maXX
®
1000 will block its output and then
wait for a specified period of time (determined by ZP0897–, called base-block time) be-
fore resuming operation. This parameter should be set at a value to ensure that any re-
sidual regeneration voltage from the motor on the output has disappeared before the
drive is activated again.
This parameter also determines the waiting time before resuming operation after external
baseblock and auto restart after fault ZP0818–.
When using a PG card with PG (encoder), speed search will begin at the actual PG (en-
coder) feedback speed.
P0898
Following a momentary power loss, the b maXX
®
1000 will start its speed search opera-
tion only if the output current is greater than the value set by ZP0898–. When the output
current is less than the value of ZP0898–, the b maXX
®
1000 output frequency is at
„speed synchronization point“. The drive will start to accelerate or decelerate back to the
operating frequency at which it was running prior to the power loss.
