GD350A series high-performance multifunction VFD
-323-
Indicator
Name
Function
LED1
State indicator
This indicator is on when the expansion card is
establishing a connection with the control board;
it blinks periodically after the expansion card is
properly connected to the control board (the
period is 1s, on for 0.5s, and off for the other
0.5s); and it is off when the expansion card is
disconnected from the control board.
LED2
Online indicator
This indicator is on when the communication
card is online and data exchange can be
performed.
It is off when the communication card is not in
the online state.
LED3
Offline/Fault indicator
This indicator is on when the communication
card is offline and data exchange cannot be
performed.
It blinks when the communication card is not in
the offline state.
It blinks at the frequency of 1 Hz when a
configuration error occurs: The length of the user
parameter data set during the initialization of the
communication card is different from that during
the network configuration.
It blinks at the frequency of 2 Hz when user
parameter data is incorrect: The length or
content of the user parameter data set during the
initialization of the communication card is
different from that during the network
configuration.
It blinks at the frequency of 4 Hz when an error
occurs in the ASIC initialization of PROFIBUS
communication.
It is off when the diagnosis function is disabled.
LED4
Power indicator
This indicator is on after the control board feeds
power to the communication card.
