Corrupt Code
1353 in corrupted state.
1353 in Fault state. Requires repair or new software
download.
11 Internal Fault
Encryption failure.
1353 in Stopped state. Requires repair and ATS test.
12 EEPROM Fault
EEPROM did not properly write, or
Checksum did not match.
All outputs stopped. Write to failed location.
13 5 V Supply Fail
External load impedance on +5 V
Supply is too low.
None. Bring voltage within range.
14 12 V Supply Fail
External load impedance on +12 V
Supply is too low.
None. Bring voltage within range.
15 External Supply Out of
Range
External load on +5 V or +12 V
exceeds 200 mA.
None. Bring external supply current
within range.
16 Flash Fault
The ash did not properly write.
1353 in Stopped state. Write to failed location.
17 Analog Input Fault
Analog input exceeds 15.5 V(voltage
input) or 7.5 K(resistance input).
None. Bring analog input within range.
18 Encoder Fault
Encoder wire open.
Encoder count stopped. Cycle KSI.
21 Overvoltage
Battery over limit. Limit = (Nominal
Voltage * 1.25) + 5 V.
All outputs stopped. Battery returns to normal range for
>1 second.
22 Undervoltage
Battery under limit.
Limit = 8.5V for 1353-4xxx
Limit = 15.5V for 1353-6xxx
All outputs stopped. Battery returns to normal range for
>1 second.
23 Overtemp
Heatsink over allowed temperature
All outputs stopped. Temp returns to normal range
(<95°C).
24 Undertemp
Heatsink below allowed.
All outputs stopped. Temp returns to normal range
(>-50°C).
25 Overcurrent
Total current exceeds 18A.
All outputs stopped. Total current returns to normal
range (≤18A).
31 Driver1 Fault
Driver is in overcurrent (>3.5 amps)
Output on the faulted driver
stopped.
Send a 0% PDO command to the
faulted driver.
32 Driver2 Fault
33 Driver3 Fault
34 Driver4 Fault
35 Driver5 Fault
36 Driver6 Fault
37 Driver7 Fault
38 Driver8 Fault
39 Driver9 Fault
