Troubleshooting the Drive 12-15
Motor
Overload 7 ➀
➂
Internal electronic
overload trip.
Enable/disable with
Fault Config 1 (238).
An excessive motor load
exists. Reduce load so
drive output current does
not exceed the current set
by Motor NP FLA (42).
OverSpeed
Limit 25 ➀ Functions such as slip
compensation or bus
regulation have
attempted to add an
output frequency
adjustment greater than
that programmed in
Overspeed Limit (83). Remove excessive load or
overhauling conditions or
increase Overspeed Limit
(83).
OverVoltage 5 ➀ DC bus voltage
exceeded maximum
value. Monitor the AC line for
high line voltage or
transient conditions. Bus
overvoltage can also be
caused by motor
regeneration. Extend the
decel time or install
dynamic brake option.
Parameter
Chksum 100 ➁ The checksum read
from the board does not
match the checksum
calculated. 1. Restore defaults.
2. Reload user set if used.
Params
Defaulted 48 The drive was
commanded to write
default values to
EEPROM. 1. Clear the fault or cycle
power to the drive.
2. Program the drive
parameters as needed.
Phase
Imbalance 37 Phase current displayed
in Imbalance Display
(221) > percentage set
in Imbalance Limit (49)
for time set in
Imbalance Time (50). Clear fault.
Phase U to
Grnd 38 A phase-to-ground fault
has been detected
between the drive and
motor in this phase. 1. Check the wiring
between the drive and
motor.
2. Check motor for
grounded phase.
3. Replace drive.
Phase V to
Grnd 39
Phase W to
