7.1 Failure and countermeasure

Possible failure types in EDS800 are shown in Table 7-1 and failure code is
from E001 to E023. 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 this table first and record failure
phenomena detailedly. Please contact our after-sale service and technical support
Department or agent in your local place when technical service is needed.

7 Troubleshooting

Table 7-1 failure type and the countermeasure
possible reason
Accelerating time is too
short
Improper V/F curve
Restart rotating motor
Low power source
voltage
Too small power of the
inverter
Decelerating time is too
short
Have potential energy
load or big inertia load
Power of inverter is a bit
small
Load change suddenly or
Have unwonted
phenomena
Accel/Decel time is set
to too short
low power source
voltage
Power of inverter is a bit
small
Unwonted input voltage
Accel time is set to too short
Restart rotating motor
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
Prolong decelerating time
Increase braking power of
external energy consumption
braking subassembly
Choose inverter with high-power
Check or reduce break of the load
Prolong accelerating decelerating
time properly
Check input power supply
Choose inverter with high-power
Check input power supply
Prolong accelerating time
