WARNING

CODE

DESCRIPTION

RECOMMENDED ACTIONS

HeatExchnger Fan

(C-FRAME ONLY)

144

The drive has detected a problem from the
Liquid-to-Air heat exchanger fans.

– Verify the Fan O/L settings and conditions
– Verify the Fan Control Relay status and

auxiliary contact signals.

Hub Comm Wrn

340

Hub (PLC) Communication Loss

– Check ControlNet adapter and cable

Inertia High

54

Indicates that the Autotune Inertia (P223)
was measured higher than 5.0 seconds.

– REFER TO THE POWERFLEX 7000

SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE

PROCEDURES, RESULTS, AND
ACTIONS

Input Close Dly

39

For PWM drives, this warning indicates that
a start command has been given, but the
drive is still waiting for the DC voltage to

discharge from the line filter capacitors.
This can be observed by the status

„Discharging‟, on the main screen. This time
can be based on the capacitor properties, or
Parameter 583 – Input Contactor Close

Delay (whichever is longer)

– Wait for the drive Ready status to

appear, allowing you to start the drive

– Verify the time in Parameter 583 is not

too long

Input Prot’n #1

65

Standard External Fault/Warning Input
included to allow the end-user to install a
protective relay (IE Input Feed Protection
Relay) auxiliary contact that can activate a

drive fault or warning, depending on
configuration of InputProt1 Class (P440).

– See associated Fault Description

Input Prot’n #2

70

Standard External Fault/Warning Input
included to allow the end-user to install a
second protective relay (IE Input Feed

Protection Relay) auxiliary contact that can
activate a drive fault or warning, depending

on configuration of InputProt2 Class (P445).

– See associated Fault Description

Input Xfmr/LR OT

66

The temperature switch in the drive Input
Isolation Transformer or Line Reactor has

detected an over-temperature and opened.
There is a thermal switch in each phase

winding, and they are connected in series.

– See associated Fault Description

Inv Heatsink FO

197

While Running, the Fiber Optic signal from

the TFB on the Inverter Heatsink, connected
to Channel A fiber optic receiver RX7 on

FOI-M-A is not present. This is only a fault
while not running. If this occurs while
running it will appear as a warning.

– Check TFB and FOI board for power
– Check the Fiber Optic cables are

properly seated in the transmitters and
receivers

– Check the fiber optic cable for kinks,

bends, breaks that could be blocking the

signal

– This can occur if the sensor is not

connected to the TFB

– NOTE: This is a warning because the

drive should not fault on the loss of the
signal while running. There is no
imminent danger to the drive, but the

user needs to be aware that there is a
temperature feedback signal missing.

Inv ChannelB FO

198

Not Normally Used: While Running, the
Fiber Optic signal from the optional TFB

connected to Channel B fiber optic receiver
RX7 on FOI-M-B is not present. This is only
a fault while not running. If this occurs while
running it will appear as a warning.
