DESCRIPTION
This warning is for liquid cool drives. Drive
has dected a problem in the Liquid to Air
heat exchanger fans.
This warning is for parallel drives only and
indicates that the drive has lost
communication with the PLC.
The drive estimated the Total Inertia is
greater than 20secs. Check Autotune Trq
Stp value and repeat. If the warning
persists, determine the inertia from system
data and if different from autotune value,
manually set Total Intertia
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.
Standard External Fault/Warning Input
included allowing 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).
Standard External Fault/Warning Input
included alllowing 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 (P444).
While Running, the drive has detected a
missing temperature sensor connected to
the TFB on the inverter heatsink. A missing
sensor can result in either a Fiber Optic
Loss fault or a Sensor fault because a
missing sensor can be interpreted as either
0°C or over 100°C, and both are unrealistic
values.
This warning is for SGCT based drives and
indicates a problem with the gate power
supply associated with a particular device
which is also likely in the warning queue.
Troubleshooting
RECOMMENDED ACTIONS
– Verify the Fan O/L settings and conditions
– Verify the Fan Control Relay status and
auxiliary contact signals.
– Verify that the Control Net adapter/cable
and PLC are working properly.
– REFER TO THE POWERFLEX 7000
MANUAL (COMMISSIONING chapter)
ON AUTOTUNE PROCEDURES,
RESULTS, AND ACTIONS
– Read DESCRIPTION
– Wait for the drive Ready status to
appear, allowing you to start the drive
– See associated Fault Description
– Also check the 120V wiring and the XIO
card.
– See associated Fault Description
– Also check the 120V wiring and the XIO
card.
– Verify sensor is completely seated
properly on TFB.
– Measure sensor resistance.
– Replace if necessary.
– Ensure that the sensor in plugged in.
– 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.
– The device feedback was not correct due
to power loss to the gate driver board.
– This can be from the 20V DC output of the
IGDPS or on the gate driver board itself.
– This warning can also appear as a result
of another device fault such as an
Online Fault.
– This warning can also appear if the
device has failed.
