Chapter 9 Faults and Solutions
9.2 fault analysis of Integrated drive system
The fault code and analysis of drive system of AS 380 series elevator integrated drive controller is
shown in table 9.2
Table 9.2 drive system fault code table
Module
protection again
st over-current
DC terminal with
excessive voltage
Check power supply and high inertia loads. Rapid stop
without dynamic braking
short circuit at periphery
Check whether the motor and the output wiring are short
circuit, whether earthing is short circuit
Check the motor and output wiring for loose
Check whether the encoder is damaged or the wiring is
correct
Phase angle self-study
incorrect
Do self-study of phase angle again
Insufficient current when
phase self-study
Increase F247 current gain when do self-study
Bad contact of hardware or
damaged
Ask professional technical personnel for Inspection
Converter
internal connectors loose
Ask professional technical personnel for Inspection
Problem in current
sampling circuit
Ambient temperature is too
high
Reduce the ambient temperature, enhance ventilation
Clean dust, cotton and other debris in the duct
Check the fan power cable for connection, or replace the
fan with the same model
Temperature detection circuit
fault
Ask professional technical personnel for Ispection
Replace the corresponding driver module
External braking
resistor short circuit
Check the braking resistor connection
Current is too large to fuse
Check whether the fuse circuit is open, or for loose
connections
Over-low input
power voltage
Motor
stall or severe load mutation
Lower load mutation to prevent motor stall
Check whether the encoder is damaged or the wiring is
correct
