- Trip information and remedies
13.1 Trip /Alarm causes and remedies
When a problem arises, diagnose it in accordance with the following table.
If it is found that replacement of parts is required or the problem cannot be solved by any remedy described in the
table, contact your Toshiba distributor.

Problem
 The acceleration time  is too short.
Overcurrent during
acceleration
 The V/F setting is improper.
 A restart signal is input to the rotating
motor after a momentary stop, etc.
 A special motor (e.g. motor with a small
impedance) is used.
 Low inductance motor especially High
speed motor is used.
 The deceleration time  is too short.

of the main circuit.
 The input voltage fluctuates abnormally.
Overvoltage during
acceleration
(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyristor is connected
to the same power distribution line.
 A restart signal is input to the rotating
motor after a momentary stop, etc.
Possible causes
 Increase the acceleration time .
 Check the V/F parameter setting.
 Use  (auto-restart) and 
 In case of pt=0, 1, 7, decrease vb.
 In case of pt=2 to 6, set f415
 Choose the higher power range drive.
 Increase the deceleration time .
 Choose the higher power range drive.
 Reduce the load fluctuation.
 Check the load (operated machine).
 Choose the higher power range drive.
 Check the secondary wiring and insulation
 Set f613=2, 3
 Contact your Toshiba distributor.
 Check the main circuit input line for phase
 Check the capacitor in the main circuit for
 Check the main circuit output line, motor,
 Select output phase failure detection
 Insert a suitable input reactor.
 Use  (auto-restart) and 
