Pwr Brd
Chksum1
104
The checksum read
from the EEPROM does
not match the
checksum calculated
from the EEPROM data.
Clear the fault or cycle
power to the drive.

➁
The checksum read
from the board does not
match the checksum
calculated.
1. Cycle power to the
drive.
2. If problem persists,
replace drive.

Programmed Current
Lmt Val (148) has been
exceeded.
Enabled/disable with
Fault Config 1 (238).
Check load requirements
and Current Lmt Val (148)
setting.

➀
The drive output current
has exceeded the
software current.
Check for excess load,
improper DC boost setting.
DC brake volts set too
high.

➀
Output transistors have
exceeded their
maximum operating
temperature.
1. Check for blocked or
dirty heat sink fins.
Verify that ambient
temperature has not
exceeded 40
°C (104°F)
for NEMA Type 1
installations or 50°C
(122°F) for Open type
installations.
2. Check fan.

➂
DC bus voltage fell
below the minimum
value of 160V DC at
200/240V input, 300V
DC at 400/480V input or
375V DC at 575V input.
Enable/disable with
Fault Config 1(233).
Monitor the incoming AC
line for low voltage or
power interruption.
