DESCRIPTION RECOMMENDED ACTIONS
InvHSnk OvrTemp 216 The temperature detection on the Inverter
Heatsink, connected to Channel A fiber optic
receiver RX7 on FOI-M-A, has exceeded
Inverter Heatsink Temperature Warning
(P316).
– Confirm actual temperature in
parameters is not higher than the
warning value – If so, investigate the
conditions of the drive (ambient /
loading/ elevation / ventilation/ filter
status / heatsink clogging)
– Check the sensor and temperature
offline (ambient) for accuracy
– Ensure that the fan is working properly
and that the air flow is sufficient in this
cabinet.
Inv AC Cur Gain 223 The current gain calculated for motor current
sensing is outside the limit of the expected
range [2 , 5 ] pu.
– Verify that the HECS ratio and burden
resistor match the drive/motor ratings.
Inv OvrVoltage 222 Motor Filter Capacitor Over Voltage. The
inverter output voltage given by Inv Output
Volt (P761) has exceeded the trip settings.
This is detected by the hardware circuit in
the ACB. A warning is logged first and if the
over-voltage persists for the time delay a
fault is logged Verify the parameters and
ensure that the motor is connected to the
drive either directly or through an output
contactor. Inspect the VSB for possible
damage.
– This warning occurs when drive is not
gating. It may be when motor is coasting.
– This is drive output V [Surface voltage
terminology used in ESP application].
– The protection uses P#193 setting but
drive calculates the motor filter cap
voltage
– Make sure there is no open circuit at the
drive output and motor is connected.
IsoTx/ReacOvrTmp 75 The temperature switch in the drive Input
Isolation Transformer or Line Reactor has
detected an over-temperature and opened
the AC input to the standard XIO opened.
There is a thermal switch in each phase
winding, and they are connected in series.
The alarm is user configurable by
parameters in Alarm Config.
– See associated Fault Description
– The alarm is user configurable by
parameters in Alarm Config. Ensure that
the cooling fan in the cabinet is working
and that the air flow is not obstructed.
– Also check the 120V wiring and the XIO
card.
L Leakage Low 68 Indicates that the Autotune L leakage
(P220) measured was less than 0.10 pu.
Verify the motor name plate data entered in
the drive.
L Leakage High 69 Indicates that the Autotune L Leakage
(P220) measured was greater than 0.35 pu.
Verify the motor name plate data entered in
the drive.
