5.2 Drive Configuration Messages
When the Mode button is pressed and held, the drive’s display will provide a 4-digit code that indicates how the
drive is configured. If the drive is in a Stop state when this is done, the display will also indicate which control source
commanded the drive to Stop (the two displays will alternate every second).
Configuration Display
Format = x.y.zz x = Control Source:
L = Local Keypad
t = Terminal Strip
r = Remote Keypad
n = Network
y = Mode:
S = Speed mode
P = PID mode
t = Torque mode
C = Sequencer mode
zz = Reference:
CP = Keypad p q
EU = 0-10 VDC (TB-5)
E1 = 4-20 mA (TB-25)
JG = Jog
nt = Network
OP = MOP
P1...P7 = Preset 1...7
01...16 = Sequencer Segment
Example:
L.S.CP = Local Keypad Start control, Speed mode, Keypad speed reference
t.p.EU = Terminal Strip Start control, PID mode, 0-10 VDC setpoint reference
t.C.12 = Terminal Strip Start control, Sequencer Operation (Speed mode), Segment #12
n.t.p2 = Network Start control, Vector Torque mode, Preset Torque #2 reference
n.S.03 = Network Start control, Speed mode, Speed reference from Sequencer segment #03
Stop Source Display
Format = x .StP L.stp = Stop command came from Local Keypad
t.stp = Stop command came from Terminal Strip
r.stp = Stop command came from Remote Keypad
n.stp = Stop command came from Network
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 F_ will not appear in the fault message.
Fault Cause Remedy (1)
f.AF High Temperature fault Drive is too hot inside • Reduce drive load
• Improve cooling
f.AL 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.
f.bf 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
f.CF Control fault An EPM has been installed that is either
blank or corrupted
f.cF Incompatible EPM fault An EPM has been installed that contains
data from an incompatible parameter
version
f.cFT Forced Translation fault An EPM from an old drive put in new drive
causes drive to trip F_cFT fault.
