Troubleshooting Chapter 4
Auto Restart (Reset/Run)
The Auto Restart feature allows the drive to automatically perform a fault reset
followed by a start attempt without user or application intervention. This
allows remote or “unattended” operation. Only certain faults are allowed to be
reset. Certain faults (Type 2) that indicate possible drive component
malfunction are not resettable.
Use caution when enabling this feature, since the drive will attempt to issue its
own start command based on user selected programming.
Fault Descriptions
Table 18 - Fault Types, Descriptions and Actions
No. Fault Type
(1)
Description Action
F2 Auxiliary Input 1 Auxiliary input interlock is open. 1. Check remote wiring.
2. Verify communications
programming for intentional
fault.
F3 Power Loss 2 FRN 5.03 and earlier only:
The DC bus voltage fell below
undervoltage level within 200 ms of
a start command, DC bus ripple
voltage is excessive, or an input
phase loss has been detected. 1. Monitor the incoming AC line for
low voltage or line power
interruption.
2. Check input fuses.
F4 UnderVoltage 1 DC bus voltage fell below the
minimum value. 1. Monitor the incoming AC line for
low voltage or line power
interruption.
2. Check input fuses.
F5 OverVoltage 1 DC bus voltage exceeded maximum
value. Monitor the AC line for high line
voltage or transient conditions. Bus
overvoltage can also be caused by
motor regeneration. Extend the
decel time or install dynamic brake
chopper.
F6 Motor Stalled 1 Drive is unable to accelerate or
decelerate motor. Increase P039 ... A147 [Accel Time x]
or reduce load so drive output
current does not exceed the current
set by parameter
A179 [Current
Limit 1].
F7 Motor Overload 1 Internal electronic overload trip. 1. An excessive motor load exists.
Reduce load so drive output
current does not exceed the
current set by parameter
P033
[Motor OL Current].
2. Verify A170 [Boost Select]
setting.
F8 Heatsink OvrTmp 1 Heatsink temperature exceeds a
predefined value. 1. Check for blocked or dirty heat
sink fins. Verify that ambient
temperature has not exceeded
45°C (113°F) for IP 30/NEMA 1/
UL Type 1 installations or 50°C
(122°F) for IP20/Open type
installations.
2. Check fan.
