4.15 S14 TWO-SPEED MOTOR 4.15.1 DESCRIPTION
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 INPUT4
is dedicated as the two-speed motor monitor and
terminals D22 and D23 are monitored for a contact closure. Closure of the contact 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.
The two-speed motor protection is enabled in
S2 SYSTEM SETUP\CURRENT SENSING
