Problem
Auto-tuning error  The motor parameter , , ,
,  are not set correctly.
 The motor with the capacity of 2 classes
or less than the inverter is used.
 The output cable is too thin.
 The inverter is used for loads other than
those of three-phase induction motors.
 The motor is not connected.
 The motor is rotating.
 Parameter pt=6 is set and High speed
motor is connected.
Ground fault  A ground fault occurs in the output cable
or the motor.
 Overcurrent of dynamic braking resistor
 When inverters are fed by AC power
supply and connected with common DC
bus link, unnecessary trip occurs.
Step-out (for PM  The motor shaft is locked.
motor drive only)  One output phase is open.
 An impact load is applied.
 Using the DC braking function.
Safe torque off error  Error of safe torque off circuit
Inverter type error  It may be a breakdown failure.
Over speed fault  The input voltage fluctuates abnormally.
 Over speed fault due to the overvoltage
limit operation.
Analog input break  The input signal from VIC is equal to or
detection fault
less than the  setting.
 A communications error occurs between
CPU communications
error control CPUs.
Over torque boost  The automatic torque boost parameter
fault
 setting is too high.
 The motor has too small impedance.
 The control CPU is defective.
CPU fault 2
Optional unit fault 2  An optional device is defective.
CPU fault 3  The control CPU is defective.
Heavy cycle of main  Main power ON/OFF during running is

repeated frequently.
 Internal failure if it is caused by other
reasons.
 PTC thermal protection is occurred.
PTC fault
Servo lock fault  The motor shaft is not locked in servo lock
operation.
Possible causes
 Set the left column parameters correctly
 Set parameter f416 to smaller 70% of
 Set the left column parameters correctly
 Then set f400=1, when trip occurs.
 Connect the motor.
 Check whether the secondary magnetic

 Choose the higher power range drive.
 Check the cable and the motor for ground
 Increase the deceleration time dec.
 Set the supply voltage correction f307
 Set the parameter f614 to 0
 Unlock the motor shaft.
 Check the interconnect cables between
 Prolong the acceleration / deceleration
 Turn off the Step-out function when using
 Contact your Toshiba distributor.
