5.3 Fault Messages
The messages below show how they will appear on the display when the drive trips. When looking at the Fault History
(P500), the
_ will not appear in the fault message.
Fault Cause Remedy (1)
. High Temperature fault Drive is too hot inside • Reduce drive load
• Improve cooling
L Assertion Level fault • Assertion Level switch is changed
during operation
• P120 is changed during operation
•
P100 or P121...P124 are set to a
value other than 0 and P120 does
not match the Assertion Level
Switch.
• Make sure the Assertion Level switch
and P120 are both set for the type
of input devices being used, prior to
setting P100 or P121...P124.
Refer to 3.2.3 and P120.
Personality fault Drive Hardware • Cycle Power
• Power down and install EPM with valid
data
• Reset the drive back to defaults (P199
= 3, 4) and then re-program
• If problem persists, contact factory
technical support
Control fault An EPM has been installed that is either
blank or corrupted
Incompatible EPM fault An EPM has been installed that contains
data from an incompatible parameter
version
Dynamic Braking fault Dynamic braking resistors are overheating • Increase active decel time
(P105, P126, P127).
• Check mains voltage and P107
External fault • P121…P124 = 21 and that digital input
has been opened.
• P121…P124 = 22 and that digital input
has been closed.
• Correct the external fault condition
• Make sure digital input is set properly
for NC or NO circuit
EPM fault EPM missing or defective Power down and replace EPM
Internal faults Contact factory technical support
Control Configuration Fault The drive is setup for REMOTE KEYPAD
control (P100=2 or 5) but is not setup to
communicate with a remote keypad Set P400 = 1, or P600 = 1
The drive is setup for NETWORK ONLY
control (P100=3) but is not setup for
network communications Set P400 or P600 to a valid network
communications protocol selection
L Loss of 4-20 mA signal fault 4-20 mA signal (at TB-25) is below 2 mA
(P163 = 1) Check signal/signal wire
. OEM Defaults data fault Drive is powered up with P199 =1 and
OEM settings in the EPM are not valid. Install an EPM containing valid OEM
Defaults data or change P199 to 0.
.H High DC Bus Voltage fault Mains voltage is too high Check mains voltage and P107
Decel time is too short, or too much regen
from motor Increase active decel time
(P105, P126, P127) or install Dynamic
Braking option
(1) The drive can only be restarted if the error message has been reset.
