stop, inverter stops output
CF1 Internal memory IC data input is
abnormal
Send back to the supplier for
maintenance
CF2 Internal memory IC data output is
abnormal
1. press RESET and set up the
parameter to be the original
value
2. Send back to the supplier for
maintenance
CF3 Inverter detects the circuit is
abnormal
Send back to the supplier for
maintenance
OFF Connecting to the ground to
protect the circuit. When the
inverter detects the output side is
connecting to the ground and the
electricity is 50% higher than the
normal electricity. Note: this
protection is for the inverter, not
for the user.
1. Check if the motor connection
is short or connects to the
ground.
2. Check if IGBT mould is
damaged.
3. Check if the circuit is poor
connection
Bb When outer multifunctional input
terminal sets up such a function,
the inverter stops output.
Clear the signal origin and bb will
disappear immediately.
CFR Automatic speed/decelerate mode
failure
1. check if the inverter and motor
are compatible
2. 負載回升慣量過大
3. overload change is too rapid
CE- Abnormal communication 1. check if the communication
signal is connected
anticlockwise.
2. check if the communication
signal is correct
CODE Software protection starts 1. In case it shows Ccode, please
send back to the supplier for
maintenance
2. In case it shows Pcode, the
password is locked.
