AS380 Series Elevator Integrated Drive Controller
223
Code
Fault
Description
Possible Cause Solution
output three-phase Power off, check whether the converter output side is
consistent with the features of DC side terminal
81
Motor
overcurrent at
low speed (in
acceleration)
Low voltage in power grid Check the input power
Abnormal motor parameters Set correct motor parameters
Quick start the motor in
operation
Restart after the motor stops rotating
Motor
overcurrent at
low speed (in
deceleration)
Low voltage in power grid Check the input power
Excessive load inertia Use appropriate braking components
Abnormal motor parameters Set correct motor parameters
Deceleration time is too
short
Extend the deceleration time
Motor
overcurrent at
low speed (in
constant speed)
Load mutation in operation
Reduce the mutation frequency and magnitude of the load
Abnormal motor parameters Set correct motor parameters
82
Encoder fault
Encoder not connected
correctly
Change Encoder wiring
Encoder has no signal output Check the Encoder and power supply
Encoder wiring disconnected Repair the disconnection
Abnormal function code
setup
Confirm the relevant functional configuration of the
converter Encoder
83
Current
detected at stop
Current not effectively
blocked when the motor
stops
Synchronous motor skid
Ask professional technical personnel for Inspection
84
Velocity
reverse
in operation
Reverse speed in operation Check the external load for mutation
Encoder is inconsistent with
the motor phase sequence
Change motor or encoder phase sequence
Motor reversal at start, and
the current reaches the
current limit
Current limit is too low, or the motor does not match
85
Velocity
detected at stop
Brake loose, the elevator car
slides
Check brake
Encoder interfered or loose Fasten encoder, eliminate interference
86
Motor phase
sequence error
Motor wiring reverse Anti-line or adjust parameters
