4.15 S14 TWO-SPEED MOTOR

4.15S14 TWO-SPEED MOTOR
The two-speed motor feature provides proper protection for a two-speed motor where there will be two different full load
values. The algorithm integrates the heating at each speed into one thermal model using a common thermal capacity used
register value for both speeds.
If the two-speed motor feature is used, Assignable Input 4 is dedicated as the two-speed motor monitor and terminals D22
and D23 are monitored for a contact closure. Contact closure signifies that the motor is in Speed 2; if the input is open, it
signifies that the motor is in Speed 1. This allows the 469 to determine which setpoints should be active at any given point
in time. Two-speed motor protection is enabled with the
setpoint.
