Troubleshooting

If the drive or motor do not operate correctly, look at the drive keypad for fault and alarm information.
• For drive faults:
– The keypad shows the fault code.
–
illuminates continuously.
– The drive shuts off output and the fault relay output activates. The motor coasts to stop.
• For drive alarms:
– The keypad shows the alarm code.
–
flashes.
– Usually, the drive will continue to operate the motor. Some alarms let you select a motor stopping method.

Fault Reset

1. Remove the cause of the fault or alarm.
2. While the keypad is showing the fault or alarm code, push
This table lists the most frequent faults and alarms with possible causes and solutions.
Refer to the Technical Manual for a full list of faults and alarms.

Sets the motor overload protection with electronic thermal protectors.
0: Disabled, 1: VTorque, 2: CT 10:1 Speed Range, 3: CT 100:1 SpeedRange, 4: PM VTorque, 5: PM CTorque,
6: VT (50Hz)
Sets the operation time for the electronic thermal protector of the drive to prevent damage to the motor. Usually it is
not necessary to change this setting.
Enables Stall Prevention during deceleration.
0: Disabled, 1: Enabled
Sets the method that the drive will use to prevent overvoltage faults when decelerating.
0: General Purpose, 1: Automatic Decel Reduction, 2: Gen Purpose w/ DB Resistor, 3: HiFlux Overexcitation,
4: HiFlux2 Overexcitation
An external baseblock command was entered
through MFDI terminal DI1 to DI8, and the drive
output stopped as shown by an external baseblock
command.
The drive received a fault reset command when a
Run command was active.
A forward command and a reverse command were
input at the same time for longer than 500 ms.
One of the digital inputs caused an external fault
through an external device.
The digital input settings are incorrect.
Overheating caused damage to the motor or the
motor insulation is not satisfactory.
The motor main circuit cable is contacting ground
to make a short circuit.
An increase in the stray capacitance of the cable and
the ground terminal caused an increase in the
leakage current.
There was a problem with the drive hardware.
Description
(RESET) or
Causes
Examine the external sequence and timing of the baseblock
command input.
Turn off the Run command then de-energize and re-energize the
drive.
Make sure that the sequence is correct. Do not set the forward and
reverse inputs at the same time.
• Find the device that caused the external faults. Remove the
cause and reset the fault.
• Make sure that the digital input terminal functions are correct.
Measure the motor insulation resistance, and replace the motor if
there is electrical conduction or unserviceable insulation.
• Examine the motor main circuit cable for damage, and repair
short circuits.
• Measure the resistance between the motor main circuit cable
and the ground terminal. If there is electrical conduction,
replace the cable.
• If the wiring length of the cable is more than 100 m, decrease
the carrier frequency.
• Decrease the stray capacitance.
Replace the control board or the drive. For information about
replacing the control board, contact the manufacturer or your
nearest sales representative.
