When momentary power loss is detected, the GS4 drive will block its output and then wait for a
specified period of time (determined by P6.23, Base-Block Time) before resuming operation. This
parameter should be set at a value to ensure that any residual voltage regenerated from the motor
onto the output has disappeared before the drive is activated again.

Following a momentary power loss, the GS4 drive will begin speed search operation only if the
output current is greater than the value set by P6.24.
When performing speed search, the V/Hz curve is determined by parameter group 1. The
maximum current for the optimum accel/decel and start speed search is set by P6.24.
The speed search current level will affect the synchronization time. The drive and motor will
synchronize faster when this parameter is set to a larger value, but a value that is too large may
activate overload protection.
