The LCD operator has split-view diagnostic screens. The diagnostics are
grouped, which makes it easier to view several related parameters. The screens
can be accessed at Home > Diag.
If a malfunction occurs during operation, the drive shuts down operation and
the keypad will display an error. Error messages can be reset by pressing
"RESET" F4 hotkey.
The LCD operator incorporates a real-time clock. This enables faults and
special events to be recorded with a timestamp in the Diagnostics Screen
Log. To set the date and time, refer to Section 4.10. With Serial/CAN keypad
operator, the clock continues even when not powered on.
The Diagnostics Screen Log can be accessed in the Diagnostics menu and
is the last screen. To access: Home > Diag > Prev.
The Diagnostics Screen Log includes drive faults (Error Overcurrent,
Overvoltage, Overload, Encoder, etc.), operation faults (e.g., Drive Enable
Dropped, Unintended Movement, Speed Following Error) Speed/Direction
Selection Error, Analog Signal/Serial Speed Command Failure, Main Contact/
Brake Switch Failure, etc.), special operation modes (Emergency Slowdown,
UPS Mode, etc.).
The EEProm will automatically create and store a new .txt file in flash memory
every 50 events. A .txt file can also be created by pressing F4 from the
diagnostic screen log. This will clear the fault log screen.
