Possible causes
 Improper setting of baud rate
 Error with serial communication
 Long period of communication
interrupt
 CANopen communication offline
 Wrong parameters setting
 Communication offline
 Wrong parameters setting
 The load exceeds the range
 Read/write fault of the control
parameters
 Damage to DPRAM chip
 Damage to the contactor
 Contactor auxiliary abnormal
 Interference
 Excessive electromagnetic
interference
 The quality of electric power is too
low
 FPGA chip damage
 DSP chip damage
 SI external fault input terminals
action
 The digital output function of the
system: rectifier enabled but the
digital terminal does not act
 Keyboard line is disconnected or
offline
 Keyboard line is too long or
interfered
 Circuit fault to the keypad or main
-55-
Goodrive3000 PWM rectifier
Countermeasures
 Set appropriate baud rate
 Press STOP/RST to reset and
contact the service department
 Check the wiring of the
communication interfaces
 Check the parameter setting and
external wiring and restore
 Please check the parameter
settings and external wiring
 Adjust the load or change another
rectifier
 Press STOP/RST to reset
 Ask for service
 Check contactor
 Check the contactor auxiliary
contact
 Check the external environment
to exclude interference
 View the unit state and ensure
FPGA is damaged or not
 Contact with us
 Check the external device input
 Press the corresponding digital
terminal and enter P5 function
group to cancel the function
 Check the environment and
eliminate the interference
 Change the hardware and ask for
service
 Change the hardware and ask for
