Troubleshooting
33
AutoReset Lim
➂
The drive unsuccessfully
attempted to reset a fault and
resumed running for the
programmed number of [Auto
Rstrt Tries]. You can enable/
disable this fault with
parameter 238 [Fault Config
1] (
Correct the cause and manually clear
the fault.
34
CAN Bus Flt
➁
A sent message was not
acknowledged.
1. Cycle the power.
2. Replace the Main Control board.
37
HeatsinkUndTp
➀
The ambient temperature is
too low.
Raise the ambient temperature.
44
Device Change
➁
The new power unit or option
board installed is a different
type.
Clear the fault and reset the drive to
the factory defaults.
45
Device Add
➁
A new option board was
added.
Clear the fault.
47
NvsReadChksum
➁
There was an error reading
parameters 9 [Elapsed MWh]
and 10 [Elapsed Run Time]
from EEPROM.
1. Cycle the power.
2. Replace the Main Control board.
48
ParamsDefault
➁
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.
54
Zero Divide
➁
This event occurred because
a mathematical function had a
dividend of zero.
1. Cycle the power.
2. Replace the main control board.
59
Gate Disable
➂ ➊
Both of the digital gate disable
inputs (SD-1 and SD-2) are
not enabled on the 20C-DG1
option board.
1. Check the motor.
2. Verify that the option board is
properly wired.
3. Replace the option board. Refer to
Appendix E -“Instructions for ATEX
Approved PowerFlex 700H Drives
in Group II Category (2)
Applications with ATEX Approved
Motors” in the
PowerFlex 700H/S
High Power Drives Installation
Manual
, publication
PFLEX-IN006… for information on
installing this option board.
60
Hrdwr Therm
➂ ➊
The thermistor input is
activated (>4k
Ω
) on the
20C-DG1 option board.
1. Check the motor.
2. The resistance of the thermistor
input must go below 2k
Ω
before
the drive can be reset.
63
Shear Pin
➂
The value programmed in
parameter 148 [Current Lmt
Val] has been exceeded. You
can enable/disable this fault
with parameter 238 [Fault
Config 1] (
Check the load requirements and the
value in [Current Lmt Val].
65
I/O Removed
➁
An I/O option board has been
removed.
Clear the fault.
70
Power Unit
➁
One or more of the output
transistors were operating in
the active region instead of
desaturation. This can be
caused by excessive
transistor current or
insufficient base drive voltage.
Clear the fault.
