Figure 148: Minimum Run Time
4.7.3.5 Acceleration Time:
The
Acceleration Time
setting is used on fixed speed machines and defines the amount of time that the
motor takes to accelerate. Setting a proper Acceleration time reduces risk of Compressor/Motor failure as
it provides a smooth loading of the Compressor. On machines with a wye-delta starter the acceleration time
will start after the wye-delta transition. To extend the time before the compressor is loaded after the wye-
delta transition, set the acceleration time to the desired value. On machines with a full voltage, soft starter,
or remote starter, the acceleration time will start after the main motor has been started and should be set
to a time sufficient to allow the main motor to accelerate to full speed before loading the compressor. Figure
