X X CabinetTemp High
(C-Frame Only)
70 The drive has a temperature switch in several cabinets, and all
the N/C switches are connected in series and fed back to the
XIO input. The levels are set differently for different cabinets.
• Identify which switch has opened, and focus on that cabinet.
• Check for proper air flow within the identified section.
• Verify that the stirring fans are operating correctly.
• Verify that the ambient temperature is within tolerances.
X Capability Limit 465 The motor current exceeded maximum allowable level for the
variable torque drive. Drive was limiting the motor current to
the safe level for drive thermal protection, but new speed
operating point cannot be achieved higher than 6 Hz.
• Ensure that the drive is not used for constant torque load condition.
X CMC Blcked Exhst 477 There is possibly blockage to the CMC exhaust/inlet airflow.
Note: This fault word is used exclusively on Heatpipe drives.
• Ensure that there are no obstructions to the path of the outgoing/incoming air flow.
• Check for cooling fan deterioration.
• Verify if the trip setting (P813/P814) matched factory recommended value.
X CMC Blcked Inlet 480 There is possibly blockage to the CMC exhaust/inlet airflow.
Note: This fault word is used exclusively on Heatpipe drives.
• Ensure that there are no obstructions to the path of the outgoing/incoming air flow.
• Check for cooling fan deterioration.
• Verify if the trip setting (P813/P814) matched factory recommended value.
X CMC Double Fans 474 The drive has just lost two or more of the cooling fans. • Verify the fan contactors, fan overload and the 120V wiring to the XIO card.
X Cnv Airflow Loss 505 The cooling airflow velocity on the specified power stack is
below the trip/warn level.
• Ensure that there are no obstructions to the path of the outgoing/incoming air flow.
• Check for cooling fan deterioration. Verify if the trip (P840) and warn setting (P841)
matched factory recommended values.
X Cnv Double Fans 473 The drive has just lost two or more of the cooling fans. • Verify the fan contactors, fan overload and the 120V wiring to the XIO card.
X CMC Fan9 Ctctr 487 Loss of the cooling fan. • Verify the fan contactor, fan overload and the 120V wiring to the XIO card.
XCnv Fan3 Ctctr 482
XCnv Fan4 Ctctr 483
XCnv Fan5 Ctctr 484
XCnv Fan6 Ctctr 485
XCnv Fan7 Ctctr 486
X Control Pwr Loss 57 There has been a loss or dip in the control power feeding the
drive for more than 5 cycles.
• Ensure that the power source is active and investigate the reliability of the source.
• Check control power input to ACB.
