Troubleshooting; Failure And Countermeasure - toscano TDS600 Serie Manual De Usuario

7. Troubleshooting

7.1. Failure and countermeasure
Possible failure types in TDS600 are shown in Table 8-1, the fault types
including fault and alarm two kinds. Such as if inverter fault display E-XX,
while the corresponding alarm is displayed in A-XX. Once the inverter failure,
fault types are stored in the F26 fault recording parameter group, and if alarm,
alarm status has been revealed, until the alarm source release, alarm status
are not logged to the F26 parameter group. Some failure code is reserved for
intelligent automatic diagnosis function which will be executed continuously
in future. When failure takes place in the inverter, the user should check
according to note of these table first and record failure phenomena detailedly.
Please contact our after-sale service and technical support Department when
technical service is needed.

Overcurrent during
E-01 accelerating
process
Overcurrent during
E-02 decelerating
process
Possible reason
Accelerating time is too short
Improper V/F curve
Restart rotating motor
Low power source voltage
Too small power of the
inverter
Output phase lose under vector
control
Decelerating time is too short
Have potential energy load or big
Inertia load
Power of inverter is a bit small

7. Troubleshooting
Countermeasure
Prolong accelerating time
Adjust V/F curve setting, adjust
manual torque boost or change to
automatic torque boost
Set speed checking restart function
Check input power supply
Choose inverter with high-power
Check whether the motor wiring is in
good condition
Prolong decelerating time
Increase braking power of external
energy consumption braking
subassembly
Choose inverter with high-power
