Description Possible causes
•The signal from system is not
inputted into input terminals.
•The input terminal function (,
) is not set up.
• A value other than 0.0 is specified
for , although the brake
answer function is not used.
•Disconnection of encoder circuit.
Speed error •Encoder error (inverter error)
(Over speed)
•Braking down of a wire for VI/II
input signal.
Abnormal • An error arises during CPU2
CPU2 communication.
communication
V/F control • An internal control error occurs.
error
• A software error occurs in the
control CPU.
Abnormal logic • An abnormal voltage is applied to
input voltage the control logic input terminal.
Add-on option 1 • Add-on option card 1 is defective.
error
Add-on option 2 • Add-on option card 2 is defective.
error
•A deviation error occurs during stop
position retaining control.
Stop position •The stop position adjustment range
retaining error specified with  is too
narrow.
•Creeping speed is too fast.
•Motor control CPU is defective.
Step-out (for •The motor shaft is locked.
PM motors •One output phase is open.
only) •An impact load is applied.
Problem Possible causes
ST-CC opened •ST terminal is in open-circuit.
Undervoltage in •The supply voltage between R, S
main circuit and T is under voltage.
•Trouble of rush current restraint
circuit or DC circuit fuse.
Retry in process •The inverter is in the process of
retry.
•A momentary stop occurred.
Frequency point •The frequency setting signals at
setting error points 1 and 2 are set too close to
alarm each other.
Clear enabling •This message is displayed when
indication pressing the STOP key while an
error code is displayed.
Emergency stop •The operation panel is used to stop
enabling the operation in automatic control
indication or remote control mode.
Setting error •An error is found in a setting when
alarm data is reading or writing.
An error code
and data are
displayed
alternately twice
each.
•Please check if the sequence is normal or not.
•Please set  or  as the input terminal to
use.
•Please set up 0.0, when you do not use system-
supporting sequence.
•Check connection of encoder.
Connect encoder correctly.
•Check connection of encoder.
Connect encoder correctly.
•Check VI/II input signal.
•Make a service call.
•Make a service call.
•Make a service call.
• Check the signal given to the logic connected with
the input terminal.
•Make a service call.
•Make a service call.
•Check connection of encoder.
•Make a service call.
•Unlock the motor shaft.
•Check the interconnect cables between the inverter
and the motor.
•Close ST-CC circuit.
•Measure the main circuit supply voltage.
If the voltage is at a normal level, the inverter
requires repairing.
•Make a service call.
•The inverter is normal if it restarts after several
tens of seconds. The inverter restarts
automatically. Be careful of the machine because it
may suddenly restart.
•Set the frequency setting signals at points 1 and 2
apart from each other.
•Press the STOP key again to clear the trip.
•Press the STOP key for an emergency stop. To
cancel the emergency stop, press any other key.
•Check whether the setting is made correctly.
