Goodrive350 IP55 High-ingress Protection Series VFD Troubleshooting
-248-
[13] Phase loss on input side
Phase loss or violent
fluctuation occurred to R,
S and T input
Check the input power;
Check installation wiring
[14] Phase loss on output side
Phase loss occurred to U,
V, W output (or the three
phases of motor is
asymmetrical)
Check the output wiring;
Check the motor and cable
[15] Overheat of rectifier
module
Air duct is blocked or fan
is damaged;
Ambient temperature is
too high;
Long-time overload
running
Ventilate the air duct or
replace the fan;
Lower the ambient
temperature
[16] Overheat of inverter
module
SI external fault input
terminal acts
Check external device input
[18] Modbus/Modbus TCP
communication fault
Baud rate is set
improperly;
Communication line fault;
Communication address
error;
Communication suffers
from strong interference
Set proper baud rate;
Check the wiring of
communication interfaces;
Set proper communication
address;
Replace or change the
wiring to enhance
anti-interference capacity
[19] Current detection fault
Poor contact of the
connector of control
board;
Hall component is
damaged;
Exception occurred to
amplification circuit
Check the connector and
re-plug;
Replace the hall
component;
Replace the main control
board
[20] Motor autotuning fault
Motor capacity does not
match with the VFD
capacity, this fault may
occur easily if the
difference between them
is exceeds five power
classes;
Motor parameter is set
improperly;
The parameters gained
from autotuning deviate
sharply from the standard
parameters;
Autotuning timeout
Change the VFD model, or
adopt V/F mode for control;
Set proper motor type and
nameplate parameters;
Empty the motor load and
carry out autotuning again;
Check motor wiring and
parameter setup;
Check whether upper limit
frequency is larger than 2/3
of the rated frequency
R/W error occurred to the
control parameters;
EEPROM is damaged
Press STOP/RST to reset;
Replace the main control
board
