 General Fault and Alarms
Faults and alarms indicate problems in the drive or in the machine.
The drive indicates that an alarm has occurred with a code on the data display screen and a
flashing ALM LED. The drive output may be shut off depending on the alarm.
The drive indicates that a fault has occurred with a code on the data display screen and a lit
ALM LED. The drive output is always switched off immediately and the motor coasts to
stop.
To remove an alarm or reset a fault, first figure out what cause the problem, take corrective
action, and finally reset the drive by pushing the RESET key on the operator or by cycling
the power supply.
The table below lists the most important alarms and faults.
LED Display AL FLT Possible Cause Corrective Action
Baseblock

The software baseblock function is assigned
to one of the digital inputs and the output is
off. The drive does not accept Up/Down
commands during this time.
• Check the functions assigned to the digital
input terminals.
• Check the upper controller sequence.
Control Fault

The torque limit was reached during deceler-
ation for longer than 3 s and one of the fol-
lowing was true:
• the load inertia is too big.
• the torque limit is too low.
• the motor parameters are set incorrectly.
• Check the load.
• Set the torque limit to the most appropriate
setting (L7-01 through L7-04).
• Check the motor parameters settings.
Control Circuit
Fault

There is a problem in the drive’s control cir-
cuit.
• Cycle the drive power supply.
• Initialize the drive.
• Replace the drive if the fault occurs again.
Cannot Reset

Fault reset was input when the Up or Down
command was active.
• Turn off the Up and Down command and
reset the drive.
• Wait until the fault restart time has expired
Speed
Deviation

F1-04 is set to 0, 1, or 2 and a speed devia-
tion higher than the value in F1-10 occurred
longer than the time set in F1-11. • Reduce the load
• Decrease the acceleration and deceleration
rate.
• Check the mechanical system (lubrication,
etc.)
• Check the setting of F1-10 and F1-11
• Check the brake sequence to make sure the
brake is fully open when acceleration
starts.

F1-04 is set to 3 and a speed deviation higher
than the value in F1-10 occurred longer than
the time set in F1-11.
