X 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.
LogixIO Config 23 The XIO card assigned to Logix I/O is not usable for this purpose. • Select the proper slot that is 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.
Low Cnv Airflow 405 The cooling airflow velocity on the specified power stack is
below the trip/warn level.
• Be sure that there are no obstructions to the path of the incoming
and/or outgoing air flow.
• Check for cooling fan deterioration.
• Verify that the trip (P840) and warn (P841) settings match the
factory recommended values.
LR Fan1 Aux 468 The specified fan was not commanded to run but its
interposing relay status indicated that the fan was turned on.
Note: This warning is used exclusively on Heatpipe drives.
• Check the fan feedback wiring and confirm with the electrical
drawings. Verify that the XIO card is functional.
LR Fan2 Aux 469
LR Fan1 Ctctr 340 Loss of the cooling fan. • Verify the fan contactor, fan overload and the 120V wiring to the
XIO card.
LR Fan2 Ctctr 341
X Master Txfr Warn 503 A transfer of Master has failed and the old Master is still the
active Master. Mastership transfer failed because of either, the
requesting drive is not allowed to take Mastership, or an
existing Follower refused to take on the role of Master.
• Check DCSL Config (P955) and Master Accept (P1045) to see if
mastership transfer is enabled.
Master UnderVolt 153 The measured line voltage (P135) or master line voltage (P136)
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 the board to confirm integrity.
• Check the TSN fusing.
• Check the actual voltage values on the terminal for each bridge and
the total line voltage.
• Check for possible source voltage supply problems.
• Use a multimeter and oscilloscope to check the voltages on the
drive test points.
MaxDrvCapability 231 The motor current exceeded maximum allowable level for the
variable torque drive. The motor current is now limited to the
safe level of drive thermal protection.
• Check the drive load condition.
• The load exceeds the expected value at desired speed.
Torque = k x speed^2, if speed is 50%, expected torque is 25%
X M Cap Comp High 377 The calculated value of motor capacitor compensation is too
large.
• Verify the motor capacitor nameplate data entered in the drive.
• Tune the drive manually.
X Minimum Capacity 505 The system has reached the minimum capacity the system can
run.
• Check the minimum capacity setting (this is the minimum number
of drives the system can run) specified in DCSL Config (P955), using
bit 3 and bit 4, Ld Factor.
