PROT-03 1027 Y LV Level (Varies with VFD rating) Sets the Low Voltage (Lv) level. Recommended setting is motor voltage
minus 10%. If incoming power varies too much, the setting may need to be
15% less than motor voltage.
If DC bus voltage drops to Lv level, the VFD stops output to the motor with
motor free run to stop. If fault occurs during acceleration, deceleration,
constant speed, or stop, then fault indication is LvA, Lvd, Lvn, and LvS,
respectively. Manual reset is required.
To enable auto restart after a momentary power loss, consult [PROT-37] and
[PROT-38] for VFD handling of fault. The hysteresis recovery level is based
on VFD frame size and VFD voltage rating.
PROT-04 1028 Y OV Stall level (Varies with VFD rating) Set Over Voltage Stall Level. If braking unit or braking resistor is con -
nected, set level to 0 to disable.
PROT-05 1029 Y OV Stall Prevent 0_Standard
1_Advanced
Set Over-Voltage Stall Prevention operation.
0_Standard: Frequency maintains during deceleration.
1_Advanced: Frequency increases during acceleration, deceleration, or
constant speed.
PROT-06 1030 Y SW Brake V Lvl (Variable) Sets the DC-bus voltage at which the DC Brake is activated. Defaults are
based on VFD Rating.
PROT-07 1031 Y OCA Level 0 to 130% Set Over-Current during Acceleration level. Value is based on VFD's rated
current and selection of [VFD-35] for Light Duty or Normal Duty.
PROT-08 1032 Y OCN Level 0 to 130% Over Current during normal running level: Set Over-Current during Opera -
tion level. Value is based on VFD's rated current and selection of [VFD-35]
for Light Duty or Normal Duty.
PROT-09 1033 Y Auto Timer Cntr 0 to 60000 If VFD does not trip during this timer, VFD will reset the counter of number
of auto restarts.
PROT-10 1034 Y Auto Restarts 0 to 10 Number of auto restart attempts after fault. When VFD trips on a fault, the
counter will decrement by one and the [PROT-11] timer will start. When the
timer expires, VFD will start the motor again. If the fault occurs again, this
cycle repeats until the counter equals zero, at which point reset is required.
If the VFD starts and continues to run for 10 minutes, the restart counter
will stay at the current value. If the VFD continues to run without fault for
six hours, the counter will reset.
Shutdown will override Restart.
PROT-11 1035 Y AutoRetry Delay 10 to 6000 sec Time delay before VFD attempts restart after fault.
FO Mode overrides Retry Delay. When FO is activated, current fault, retry
delay, and restart counter will be reset.
If Run command is removed with timer active, timer will finish and fault
will be reset.
PROT-12 1036 Y OL-2 Type 0_Disable
1_Alarm at Speed
2_Trip at Speed
3_Alarm at Run
4_Trip at Run
Select Overload Detection operation. Setting 1 and 2 protects from Over -
load once VFD reaches constant speed. Setting 3 and 4 protects from Over -
load throughout run of the motor.
PROT-13 1037 Y OL-2 Level 10 to 200% Set Overload Detection level with respect to the rated current of the VFD.
PROT-14 1038 Y OL-2 Delay 0.0 to 60 sec Duration output current exceeds the overload detection level causing an
Overload condition. The hysteresis for the Overload condition is 5% of
detection level.
PROT-15 1039 Y OCA/OCN
ACC/DEC
0_ACC/DEC-1
1_ACC/DEC-2
2_ACC/DEC-3
3_ACC/DEC-4
Over Current during Acceleration / Over Current during Normal Running
Acceleration Time / Deceleration Time
When over-current condition OCA or OCN is detected, VFD will change
ACC/DEC rate to selected rate.
PROT-16 1040 Y ETH Type 0_Disable
1_Self-Cooled
2_Force-Cooled
Set type of motor for Electronic Thermal Relay protection. For 1_Self-Cooled ,
the motor rated current percentage level is 40% at 0Hz and linear
increases to 100% at motor rated frequency.
PROT-17 1041 Y ETH Delay 30 to 600 sec Sets time the output current is higher than 150% before tripping on elec -
tronic thermal overload. The overload level with respect to time is based
on I
2
t curve.
