Appears only if STARTER TYPE is set as FV REVERSING or TWO SPEED. With
two-speed starters, this delay is required when the motor is switched
from high speed (Contactor B) to low speed (Contactor A). The delay
starts when Contactor B drops out. With a reversing starter, this delay
occurs when switching from forward (Contactor A) to reverse (Contactor
B) and from reverse to forward.
Range: ENABLE, DISABLE
Appears only if STARTER TYPE is selected as TWO SPEED. When disabled,
the MM3 allows the motor to be started directly to high speed. When
enabled, the motor must be started in low speed before switching to high
speed.

common wiring practice.
