Warning / Self-diagnosis Detection Function
10.3.
When the inverter detects a warning, the keypad displays a warning code (flash).
Note:
The fault contact output does not energize on a warning and the inverter continues operation. When the warning is no longer
active the keypad will return to its original state.
When the inverter detected a programming error (for example two parameters contradict each other of are set
to an invalid setting), the keypad displays a self-diagnostics code.
Note:
The fault contact output does not energize on a self-diagnostics error. While a self-diagnostics code is active the inverter does not
accept a run command until the programming error is corrected.
Note:
When a warning or self- diagnostic error is active the warning or error code will flash on the keypad.
When the RESET key is pressed, the warning message (flash) disappears and returns after 5 sec. If the warn-
ing or self-diagnostic error still exists.
Refer to Table 10.3.1 for and overview, cause and corrective action for inverter warnings and self-diagnostic
errors.
VDI100 • Instruction manual
Description
• Multifunction digital input external fault
active.
• SLV mode is unable to run motor
•Start or Run fault in PMSLV mode
• IGBT damaged.
• Short circuit output terminals.
• LCD keypad and inverter cannot transmit data
after power on 5 seconds
• LCD keypad and inverter can transmit data
but transmission error occurs for more than 2
seconds
Cause
• Multi-function input function set incorrectly.
• Check wiring
•Perform rotational or stationary auto-tune
•Increase minimum output frequency (01-08
•Increase the value of 22-10 and 22-23
properly.
•Re auto-tune (22-21).
•Check if the load is too heavy to raise torque
output limit.
•Check IGBTs
•Check for short circuit at inverter output.
•Replace inverter.
•Disconnect the operator and then reconnect.
•Replace the control board
•Disconnect the operator and then reconnect.
•Replace the control board
