Code
Fault
Description
Possible Cause Solution
incorrect
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
72
ADC failure
Current sensor damaged Replace current sensor
Problem in current
sampling circuit
Replace control board
73
Radiator overhe
ating
Ambient temperature is too
high
Reduce the ambient temperature, enhance ventilation
Duct obstruction Clean dust, cotton and other debris in the duct
Fan abnormal 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
74
Brake unit
failure
Brake unit damaged Replace the corresponding driver module
External braking
resistor short circuit
Check the braking resistor connection
75
Fuse-off failure
Current is too large to fuse Check whether the fuse circuit is open, or for loose
connections
76
Over
output torque
Over-low input
power voltage
Check the input power
Motor
stall or severe load mutation
Lower load mutation to prevent motor stall
Encoder fault Check whether the encoder is damaged or the wiring is
correct
Open phase for output Check the motor and output wiring for loose connections
77
Speed deviation
Acceleration time is too
short
Extend the acceleration time
Overloaded Reduce the load
Current limit is too low Increase the limit value in the allowable range
78
(In
accelerated runni
g)
Bus over-voltag
Abnormal input
power voltage
Check the input power
The motor is quick restarted
again in high-speed rotation
Stop and restart the motor
