Two additional acceleration timers are provided for the two speed motor feature. One
timer is for a start in Speed 2 from a stopped condition. The other is an acceleration timer
for the transition from Speed 1 to Speed 2. Also, while the motor is running, the 469 will
ignore Mechanical Jam protection during the acceleration from Speed 1 to Speed 2 until
the motor current has dropped below Speed 2 FLA × Overload Pickup value, or the Speed
1-2 acceleration time has expired. At that point in time, the Mechanical Jam feature will be
enabled with the Speed 2 FLA.
