TD Series Digital Solid State Soft Starter 48 - 1250A
F026 = Begin Decel Level (BDL)
Factory Setting = 60%
Range = 0 - 100% of line voltage
Use to drop voltage to a level where there is a noticeable effect on
motor torque during decel mode.
F027 = Decel Shut Off Voltage
Factory Setting = 30%
Range = 0 to (BDL -1)%
Sets the level where motor torque during decel is no longer effective.
Always set this function lower than the setting of F026, Begin Decel
Level.
F028 = Decel Ramp Time
Factory Setting = 10 seconds
Range = 1 - 60 seconds
Sets the maximum time for the deceleration ramp to go from the Begin
Decel Level setting (F026) to the Decel Shut Off Voltage (F027). Since
motor heating increases as voltage is lowered, the setting should not
exceed the time necessary to achieve the deceleration effect.
F029 = Reserved
5.5.6 Protection Features
F030 = Current Imbalance Trip
Factory Setting = 0 (Disabled)
Range = 0 - 1
If F030 = 1 (Enabled), starter will trip when the output current between
any two phases exceeds the amount set with F031 for the time specified
with F032.
F031 = Current Imbalance Trip %
Factory Setting = 10%
Range = 5 - 30%
Use to set the trip level for current imbalance between any two phases.
Percentage is based on FLA (F001 setting).
F032 = Current Imbalance Trip Delay
Factory Setting = 2 seconds
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-duration
transients. Using default settings, if the difference in output current
between two phases exceeds 10% of FLA for more than 2 seconds,
the starter will trip.
F033 = Over Current / Shear Pin Trip
Factory Setting = 0 (Disabled)
Range = 0 - 1
If F033 = 1 (Enabled), starter will trip when the output current of any
phase exceeds the amount set with F034 for the time specified with
F035. Can be referred to as a “Shear Pin Trip” and can be used to
protect mechanical components from breaking due to jammed loads.
F034 = Over Current Trip %
Factory Setting = 125%
Range = 100 - 300%
Use to set the trip level for an over current condition for any phase.
Percentage is based on FLA (F001 setting).
Over Current Trip
(F033 = 1)
