SET-40 0040 Y OverPress Level 0.0 to [SET-20] ( [SET-19] Unit) Level the process signal (pressure) reaches to cause an overpressure condi -
tion.
SET-41 0041 N ULD Select 0_Disabled
1_By Current
2_By Torque
Underload Detection protects against conditions such as a dry well, broken
pump, or broken drive belt. Refer to “Underload Protection (Dry Well or Belt
Loss)” on page 93 .
SET-42 0042 Y ULD Level 15 to 115% Underload Level set as a percentage of FLA (SFA). If current is below this
level and frequency is above ULD Frequency [SET–43] for longer than ULD Delay
[SET–44] timer, VFD will trip on ULD.
SET-43 0043 Y ULD Frequency [SET-22] to [SET-23] (Hz) If motor runs above ULD Frequency, VFD compares operating current with
ULD Level [SET–42] to detect a ULD condition.
SET-44 0044 Y ULD Delay 0 to 360 sec Underload Delay timer before trip.
SET-45 0045 Y ULD Recovery T 0 to 720 min Underload Recovery Time. VFD will restart from ULD trip after this time. If it
trips again, time will be doubled up to 720 min. If set to 0, fault must be
manually reset.
SET-46 0046 N ULD Recover Cnt 0 to 720 min Decrementing counter of recovery time from an ULD trip before VFD
attempts to restart motor (Read Only).
SET-47 0047 N HLD Select 0_Disabled
1_By Current
2_By Torque
High Load Detection protects the VFD and motor against damage from an
over-torque condition. Refer to “High Load Detection” on page 92 .
SET-48 0048 Y HLD Level 75 to 200% High Load Detection level, set as a percentage of FLA (SFA). If current is
above this level and frequency is above HLD Frequency [SET–49] for longer than
HLD Delay [SET–50] timer, VFD will trip on HLD.
SET-49 0049 Y HLD Frequency [SET-22] to [SET-23] (Hz) If motor runs above HLD Frequency, VFD compares operating current with
HLD Level [SET–48] to detect an HLD condition.
SET-50 0050 Y HLD Delay 0 to 360 sec High Load Delay timer before trip.
SET-51 0051 Y HLD Recovery T 0 to 720 min High Load Detection Recovery Time: VFD will restart from HLD trip after this
time. If it immediately trips again, time will be doubled up to 720 min. If set
to 0, fault must be manually reset.
SET-52 0052 Y HLD Recover Cnt 0 to 720 min High Load Detection Recovery Count: Decrementing counter of recovery
time from a HLD trip before VFD attempts to restart motor (Read Only).
SET-53 0053 Y ACC Change Freq 0.0 to [SET-14] (Hz) Frequency to switch from main accel/decel rate to second accel/decel rate.
SET-54 0054 Y Second ACC 0 to 6000 sec Time in seconds for drive to accelerate from 0 Hz to maximum frequency.
Second acceleration occurs when frequency is above ACC Change Freq [SET-53] .
For example, submersibles have to be accelerated up to 30hz in 1 second
but they can accelerate from 30hz to 60hz much slower. So, we would
adjust [SET-53] to 30hz and the drive would follow the [SET-11] ACC time up to
30hz and the [SET-54] ACC time above 30hz.
SET-55 0055 Y Second DEC 0 to 6000 sec When Stop Mode is set to Decelerate, time in seconds to slow down from
maximum frequency to 0 Hz. Second deceleration occurs when frequency is
above ACC Change Freq [SET-53] . VFD returns to main DEC time when frequency
is below [SET-53] - [SET-56] .
SET-56 0056 Y ACC/DEC Hyster 0.0 to [SET-53] (Hz) When 2nd ACC/DEC time is activated and frequency drops below [SET-53] -
[SET-56] , VFD will switch to main ACC/DEC time.
