Correcting Faults

The recommended corrective action for faults is:

•

Use the Fault listing table below to find and address the

root cause of the problem .

• Reset the drive . See

Fault Resetting on page 78

Table 55: Fault Listing

Fault Code

Fault Name In Panel

Description and Recommended Corrective Action

OVERCURRENT

Output current is excessive . Check for and correct:

• Excessive motor load .

• Insufficient acceleration time (parameters 2202 ACCELER TIME 1).

• Faulty motor, motor cables or connections .

DC OVERVOLT

Intermediate circuit DC voltage is excessive . Check for and correct:

• Static or transient overvoltages in the input power supply .

• Insufficient deceleration time (parameters 2203 DECELER TIME 1).

DEV OVERTEMP

Drive heatsink is overheated . Temperature is at or above limit .

R1…R4 & R7/R8: 115 °C (239 °F) R5/R6: 125 °C (257 °F)

Check for and correct:

• Fan failure .

• Obstructions in the air flow.

• Dirt or dust coating on the heat sink .

• Excessive ambient temperature .

• Excessive motor load .

SHORT CIRC

Fault current . Check for and correct:

• A short-circuit in the motor cable(s) or motor .

• Supply disturbances .

RESERVED

Not used .

DC UNDERVOLT

Intermediate circuit DC voltage is not sufficient. Check for and correct:

• Missing phase in the input power supply .

• Blown fuse .

• Undervoltage on mains .

MOT TEMP

Motor is too hot, based on either the drive’s estimate or on temperature feedback .

• Check for overloaded motor .

• Adjust the parameters used for the estimate (3005…3009) .

PANEL LOSS

Panel communication is lost and either:

• Drive is in local control mode (the control panel displays HAND or OFF), or

• Drive is in remote control mode (AUTO) and is parameterized to accept start/stop, direction or reference from the

control panel .

To correct check:

• Communication lines and connections

• Parameter 3002 PANEL COMM ERROR .

• Parameters in Group 10: START/STOP/DIR and Group 11: REFERENCE SELECT (if drive operation is AUTO) .

ID RUN FAIL

The motor ID run was not completed successfully . Check for and correct:

• Motor connections

• Motor parameters 9905…9909

MOTOR STALL

Motor or process stall . Motor is operating in the stall region . Check for and correct:

• Excessive load .

• Insufficient motor power.

EXTERNAL FLT 1

Digital input defined to report first external fault is active. See parameter 3003 EXTERNAL FAULT 1.
