8–4 Troubleshooting
Ill Prog Input
62 [Fault Data] = 98 – “3 Wire” is
selected as the [Input Mode] and
one or more digital inputs are pro-
grammed to “Run Reverse” (2
wire action). Reprogram the digital inputs or select
“2 Wire” as the [Input Mode].
Input Phase Flt
49 The DC bus ripple has exceeded
the value in [Phase Loss Level]. 1. If the drive is operated on single-
phase, the load derating level has
been exceeded.
2. Check incoming power for a miss-
ing phase/blown fuse.
Load Loss Flt
20 [Load Loss Detect] is set to
“Enabled” and the drive output
torque current was below [Load
Loss Level] for a time period
greater than [Load Loss time]. 1. Verify connections between motor
and load.
2. Verify level and time requirements
or disable [Load Loss Detect].
Loop Overrn Flt
23 An overrun of the 2.5ms control
loop has occurred. Check all connections to the Main
Control Board. Replace the board or
complete drive as needed.
Max Retries Fault
33 Drive unsuccessfully attempted to
reset a fault and resume running
for the programmed number of
[Reset/Run Tries]. Check fault buffer for fault code requir-
ing reset. Correct the cause of the
fault and manually clear by pressing
the local Stop key or cycling the TB5
Stop input.
Motor Mode Flt
24 A fault has been detected originat-
ing from the Control Board. Check all connections to the Control
Board. Replace the board or complete
drive as required.
Motor Stall Fault
06 Current remained over 150% of
[Rated Amps] for more than 4 sec-
onds. If the motor is drawing excessive cur-
rent (over 150%), the motor load is
excessive and will not allow the drive
to accelerate to set speed. A longer
accel time or a reduced load may be
required.
Motor Thermistor
15 An analog option board with ther-
mistor input is installed and the
value at the terminals is less than
60 ohms or greater than 3300
ohms. 1. Verify that thermistor is connected.
2. Motor is overheated. Reduce load.
3. Thermistor is not present. Remove
option board.
Mult Prog Input
61 A single source input function
such as Reverse/Forward
(open=1
st function, closed=2 nd
function) has been programmed
to more than one input or more
than one “Run Reverse” input.
Reprogram one or more of the inputs
to a different value.
Neg Slope Fault
35 Drive software detected a portion
of the volts/hertz curve with a neg-
ative slope. Check drive programming.
1. [Base Voltage] parameter must be
greater than [Start Boost].
2. If the [DC Boost Select] parameter
is set to “Full Custom,” [Base Volt-
age] must be greater than [Break
Voltage] and [Break Voltage] must
be greater than [Start Boost].
Open Pot Fault
09 An external pot is connected and
the common side of the pot is
open. The drive generates this
fault when the voltage between
pot leads is greater than 3.9V DC. Check the external potentiometer cir-
cuit at TB2 for an open circuit.
