7 Troubleshooting
MAGNETEK HPV1000 AC Elevator Drive Technical Manual 47
EF1
Ext Flt S1 Alarm
External fault at Logic Input 1 on
terminal S1.
An external device has tripped an alarm function.
• Remove the cause of the external fault and reset the fault.
Wiring is incorrect.
• Ensure the signal lines have been connected properly to the terminals
assigned for external fault detection.
• Reconnect the signal line.
Incorrect Logic Input settings.
• Check for incorrect setting of Logic Inputs in the C2 sub-menu for external
faults.
EF2
Ext Flt S2 Alarm
External fault at Logic Input 2 on
terminal S2.
EF3
Ext Flt 3
Ext Flt S3 Alarm
External fault at Logic Input 3 on
terminal S3.
EF4
Ext Flt 4
Ext Flt S4 Alarm
External fault at Logic Input 4 on
terminal S4.
EF5
Ext Flt 5
Ext Flt S5 Alarm
External fault at Logic Input 5 on
terminal S5.
EF6
Ext Flt 6
Ext Flt S6 Alarm
External fault at Logic Input 6 on
terminal S6.
EF7
Ext Flt 7
Ext Flt S7 Alarm
External fault at Logic Input 7 on
terminal S7.
EF8
Ext Flt 8
Ext Flt S8 Alarm

terminal S8.
End1
(auto-tune)
Excessive V/f Setting (detected only
during Rotational Auto-Tuning, and
displayed after Auto-Tuning is complete).
The torque reference exceeded 20% during Auto-Tuning, or the results from
Auto-Tuning the no-load current exceeded 80%.
• Before Auto-Tuning the drive, verify the information written on the motor
nameplate and enter the data in to the A5 menu and verify in the U9 menu.
• Enter parameters and repeat Auto-Tuning.
End2
(auto-tune)
Motor Iron-Core Saturation Coefficient
(detected only during Rotational
Auto-Tuning and displayed after
Auto-Tuning is complete).
Motor data entered during Auto-Tuning was incorrect.
• Make sure the data entered match the information written on the motor
nameplate.
• Restart Auto-Tuning and enter the correct information.
Results from Auto-Tuning are outside the parameter setting range, assigning
the Saturation Comp 1 and Saturation Comp 2 parameters a temporary value.
• Check and correct faulty motor wiring.
End3
(auto-tune)
Rated Current Setting Alarm (displayed
after Auto-Tuning is complete)
The correct current rating printed on the nameplate was not entered into
Rated Current in the U9 sub-menu during Auto-Tune.
• Check the setting of parameter Rated Current in the U9 sub-menu.
• Check the motor data and repeat Auto-Tuning.
End4
(auto-tune)
Adjusted Slip Calculation Error
The slip that was calculated is outside the allowable range.
• Make sure the data entered for Auto-Tuning in the U9 sub-menu is correct.
• Execute the “Standard Tuning” in the U9 sub-menu for a rotational
auto-tune. If a rotational auto-tune cannot be done, try “Tune-No Rotate2.”
End5
(auto-tune)
Resistance Tuning Error
The resistance value that was calculated is outside the allowable range.
• Double-check the data that was entered for the Auto-Tuning process.
• Check the motor and motor cable connection for faults.
End6
(auto-tune)
Leakage Inductance Alarm
Control Method (U8) setting error.
• Check the setting of Control Method (U8).
• Check the control mode and repeat Auto-Tuning.
The leakage inductance value that was calculated is outside the allowable
range.
• Double-check the data that was entered for the auto-tune process in Leak
Inductance (A5).
