13.1 Trip causes/warnings 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 dealer.

Problem Possible causes
• The acceleration time  is too short.
• The V/F setting is improper.
• A restart signal is imput to the rotating motor
after a momentary stop, etc.
• A special motor (e.g. motor with a small
impedance) is used.
• There is possibility of Ground fault trip.
• The deceleration time  is too short.
• There is possibility of Ground fault trip.
• The load fluctuates abruptly.
• The load is in an abnormal condition.
• There is possibility of Ground fault trip.
• A current leaked from an output cable or the
motor to ground.
• A main circuit elements is defective.
• See "OH" trip information in the next page.
(for 200V: 11 to 18.5kW, 400V: 15 to 18.5kW
models only)
• The insulation of the output main circuit or
motor is defective.
• The motor has too small impedance.
• 200V: 11 to 18.5kW, 400V: 15 to 18.5kW
model was started, although a current is
leaked from an output cable or the motor to
ground.
• A main circuit elements is defective.
• There is possibility of Ground fault trip.
• A phase failure occured in the input line of
the main circuit.
• The input voltage fluctuates abnormally.
• A phase failure occurred in the output line of
the main circuit.

Remedies
• Increase the acceleration time .
• Check the V/F parameter.
• Use  (auto-restart) and 
(coast stop).
• Adjust the carrier frequency .
• Set the carrier frequency control mode
selection parameter  to 1 or 3
(carrier frequency decreased automatically).
• Increase the deceleration time .
• Set the carrier frequency control mode
selection parameter  to 1 or 3
(carrier frequency decreased automatically).
• Reduce the load fluctuation.
• Check the load (operated machine).
• Set the carrier frequency control mode
selection parameter  to 1 or 3
(carrier frequency decreased automatically).
• Check cables, connectors, and so on for
ground faults.
• Make a service call.
• See "OH" trip information in the next page.
(for 200V: 11 to 18.5kW, 400V: 15 to 18.5kW
models only)
• Check the cables and wires for defective
insulation.
• When using 200V: 11 to 18.5kW, 400V: 15
to 18.5kW model, check cables, connectors,
and so on for ground faults.
• Make a service call.
• Check the main circuit input line for phase
failure.
• Enable  (input phase failure
detection).
• Check the capacitor in the main circuit for
exhaustion.
• Make a service call.
• Check the main circuit output line, motor,
etc. for phase failure.
• Enable  (Output phase failure
detection).
