DigInCflctC 2 More than one physical input has been configured to the same input function. Multiple
configurations are not allowed for the following input functions.

FB Cfg Cflct 2 One of the following has occurred:
• Par
414 [Fdbk Device Type] does not equal 3 “Armature” and Par 478 [Spd Loss Flt Cfg] is
set to “Alarm” while Par 458 [SpdReg FB Bypass] is set to “Disabled”.
• Par 414 [Fdbk Device Type] is set to 4 “Resolver” and Pars 429 [Resolver Pos Sel], 430
[Resolver Spd Sel], 786 [PID Source], 1204 [Line Spd Source], or 1284 [Ref Spd Source] are
selecting a resolver signal.
• Par 414 [Fdbk Device Type] is set to 1 “Encoder” and Pars 786, 1021, 1204, or 1284 are
selecting an encoder signal.
FldCfg Cflct 2 The selected operating mode of the field controller is in conflict with another setting in the
drive or a permanent magnet motor is incorrectly configured. This alarm displays under the
following conditions:
• Par
469 [Field Mode Sel] = “Field Weaken” or “External” and Par 458 [SpdReg FB Bypass]
= “Enabled”
• Par 469 [Field Mode Sel] = “Field Weaken” or “External” and Par 414 [Fdbk Device Type]
= “Armature”
• Par 469 [Field Mode Sel] = “Field Weaken” or “External” and Par 478 [Spd Loss Flt Cfg] =
“Alarm”
• Par 469 [Field Mode Sel] = “Field Weaken” or “Base Speed” and Par 497 [Field Reg En] =
“Disabled”
• Par 469 [Field Mode Sel] = “Base Speed” and Par 498 [Force Min Field] = “Enabled”
• Par 469 [Field Mode Sel] = “Base Speed” and Par 133 … 144 [Digital Inx Sel] = “Force
Min Fld”
Fld Current Loss 1 The field current is too low. See the “Fld Current Loss” fault description on page 202 for more
information.
Motor Overload 1 The selected motor overload current level has been exceeded. See the “Motor Overload” fault
description on
page 203 for more information.
Motor Over Temp 1 The motor has exceeded its temperature rating (as signaled by the thermistor connected to
the drive terminals 78 and 79). See the “Motor Over Temp” fault description on
page 203 for
more information.
Ref Cflct 2 1. More than one of the drive's reference inputs (Pars 70 , 75 and 80 [Anlg Inx Sel], Pars
1323 … 1327 [DPI Px Select], Par 1021 [Encoder Out Sel], or Par 430 [Resolver Spd Sel])
are set to the same value. See Figure 80 on page 280 or Speed Reference Selection on
page 317 for a graphical representation of the drive's reference selections.
2. Both Pars 429 [Resolver Pos Sel] and 430 [Resolver Spd Sel] are non-zero.
3. More than one of the following parameters contains the same value: 786 [PID Source],
1204 [Line Spd Source], and 1284 [Ref Spd Source].
Spd Fdbk Err 1 With Par 478 [Spd Loss Flt Cfg] set to 1 “Alarm” an error condition associated with the
selected speed feedback device (analog tachometer, encoder, or resolver) was detected.
Spd Fdbk Loss 1 With Par 478 [Spd Loss Flt Cfg] set to 1 “Alarm”, the speed feedback device selected in Par 414
[Fdbk Device Type] is indicating less than 5% of Par 162 [Max Feedback Spd] while the
measured armature voltage is greater than the value of Par 455 [Spd FB Loss Lvl]. See the
“Spd Fdbk Loss” fault description on page 204 for more information.
Start At PowerUp 1 Par 1344 [Start At Powerup] is enabled. The drive may start at any time after drive power up
and the time specified in Par 1345 [Powerup Delay] has elapsed.
