Table 10 Fault Types, Descriptions, and Actions

➊ See Table 9 for internal drive fault types.

No. Fault

Type

➊

Description Action

F2 Auxiliary Input 1 Auxiliary input interlock is open. 1. Check remote wiring.

2. Verify communications.

F3 Power Loss 2 DC bus voltage remained below

85% of nominal.

1. Monitor the incoming AC line for low voltage or line power interruption.

2. Check input fuses.

F4 UnderVoltage 1 DC bus voltage fell below the

minimum value.

Monitor the incoming AC line for low voltage or line power interruption.

F5 OverVoltage 1 DC bus voltage exceeded

maximum value.

Monitor the AC line for high line voltage or transient conditions. Bus

overvoltage can also be caused by motor regeneration. Extend the decel time

or install dynamic brake option.

F6 Motor Stalled 1 Drive is unable to accelerate motor. Increase Parameter 139…167 (Accel Time x) or reduce load so drive output

current does not exceed the current set by Parameter 189 (Current Limit 1).

F7 Motor Overload 1 Internal electronic overload trip 1. An excessive motor load exists. Reduce load so drive output current

does not exceed the current set by Parameter 133 (Motor OL Current).

2. Verify Parameter 184 (Boost Select) setting

F8 Heatsink

OvrTmp

1 Heatsink temperature exceeds a

predefined value.

1. Check for blocked or dirty heat sink fins. Verify that ambient

temperature has not exceeded 40°C.

2. Replace internal fan.

F12 HW OverCurrent 2 The drive output current has

exceeded the hardware current

limit.

Check programming. Check for excess load, improper programming of

Parameter 184 (Boost Select), DC brake volts set too high, or other causes of

excess current.

F13 Ground Fault 2 A current path to earth ground has

been detected at one or more of the

drive output terminals.

Check the motor and external wiring to the drive output terminals for a

grounded condition.

F33 Auto Rstrt Tries Drive unsuccessfully attempted to

reset a fault and resume running

for the programmed number of

Parameter 192 (Auto Rstrt Tries).

Correct the cause of the fault and manually clear.

F38

F39

F40

Phase U to Gnd

Phase V to Gnd

Phase W to Gnd

2 A phase to ground fault has been

detected between the drive and

motor in this phase.

1. Check the wiring between the drive and motor.

2. Check motor for grounded phase.

3. Replace starter module if fault cannot be cleared.

F41

F42

F43

Phase UV Short

Phase UW Short

Phase VW Short

2 Excessive current has been

detected between these two output

terminals.

1. Check the motor and drive output terminal wiring for a shorted

condition.

2. Replace starter module if fault cannot be cleared.
