Goodrive300-01A series VFD for air compressor Fault information and troubleshooting
-69-
• Stator winding of 3PH of
the fan is abnormal.
• Poor grid quality.
contacted.
• Measure whether the 3PH
winding impedance of the
fan is balanced.
• Increase the set value of
P21.03 properly to lower
down the sensitivity during
determining imbalance
degree.
• Encoder line sequence
error.
• Encoder damaged.
• Check encoder wiring.
• Check whether the pulse
number setting of P20.01
encoder is set correctly.
• Replace the encoder.
Encoder speed signal is
contrary to the motor running
direction.
Reset P20.02 encoder direction.
Z signal wire disconnected.
Check the wiring of Z signal
wire.
Touch screen
communication
interrupted
485 communication port is
disconnected.
Check whether communication
line is loosened.
6.2 Fault contents and solutions of air compressor equipment
Abnormal state and solutions of air compressor equipment:
Check air filter after stop.
Check oil filter after stop.
Check the separator after stop.
Precision splitter
blocked
Precision splitter is
abnormal.
Check the precision splitter after
stop.
Actual voltage is detected
by P1 to be larger than the
pre-alarm voltage set by
P18.17.
• Check whether solenoid valve
is normal.
• Check whether pressure
control parameters are set
correctly.
Actual temperature
detected by PT1 is higher
than the pre-alarm
temperature set by P18.19.
• Check whether fan control
parameters are set correctly.
• Whether the fan operates
normally.
