DESCRIPTION RECOMMENDED ACTIONS
Liqd IO Conflict
(C-Frame Only)
22 The XIO card previously being used for
Liquid Cooling System Faults has been
reassigned for another purpose.
– Check the configuration of all XIO slots
and reassign if necessary.
– Read DESCRIPTION
LogixIO Config 23 XIO Card assigned to Logix IO is unsable
for this purpose.
– Select the proper slot compatible for
usage.
LogixIO Conflict 24 Logix IO card has been re-assigned for
another purpose.
– Check configuration of all cards and
reassign if necessary.
Master UnderVolt 153 The measured Line voltage or Master Line
Volt (P135-136) is less than Line
Undervoltage level (P167) with respect to
1/3 Rated Line Voltage (P18) [for 18-pulse
drives], and Rated Line Voltage (P18) [for 6-
pulse and PWM drives] for the period set by
Line Undervoltage Delay (P168).
– Verify the VSB connections and tap
settings, and check resistance of VSB
board – Megger board to confirm integrity
– Check TSN fusing
– Check actual voltage values on the
Terminal for each bridge and the total
line voltage
– Check for possible source voltage
supply problems
– Use Multimeter and Oscilloscope to
check voltages on the drive test points
Motor Cap Range 137 The calculated per unit value of the Motor
Filter Capacitor (P128), based on the values
entered for Motor Capacitor kVAR (P20),
Motor Capacitor Volts (P21), and Motor
Capacitor Frequency (P28) is outside of the
normal range of 0.26-0.55 pu.
– Verify capacitor nameplate data and
compare with information entered in
drive for drive rating and motor rating
– Contact factory
Motor Load Loss 138 The drive has detected a loss of load
condition. This is activated as a warning
using the parameter Load Loss Detect
(P199), and the necessary setpoints are
Load Loss Level (P246), Load Loss Delay
(P231), and Load Loss Speed (P259).
– Verify the parameter settings
– Ensure that the load should not normally
be in an unloaded condition
Motor OvrLoad 136 A Motor Overload (P550) warning has been
detected, where the overload condition is
calculated using Stator Current (P340) and
Motor Overload Warning (P351) as the point
where the overload warning occurs. P351 is
programmed as a percentage of the
difference between Motor Overload Min
(P350) and Motor Overload Trip (P179).
– Transient Loading - Check torque limit
and overload settings and Compare
loading to torque settings and trip
settings
– Verify the drive sizing and that the
overload parameters to meet the load
requirements. Verify HECS feedback
and burden resistors.
