Table 7-8 "Minor Failure/ Warning" Display Details and Remedies (Continued)
LED display Minor failure name
Uv
Main circuit low voltage
The following states occurred when no driving command is inputted (when
the VFD is not operating).
⇒
The inrush current suppression contactor inside the VFD was released.
⇒
The control power supply became low.
Cause Measure
Phase interruption of the input
power supply occurred.
Check the main circuit power supply wiring for a break or wrong wiring.
⇒
Perform wiring correctly.
The wiring terminal of the input
power supply is loose.
Check the terminal for looseness.
⇒
Re-tighten the terminal.
An error occurred in the power
supply voltage.
Check the voltage.
⇒
Adjust the voltage to the range of the power supply specification of the
VFD.
Power failure occurred.
⇒
Adjust the power supply
The power supply voltage drops
at an inrush current of the VFD due to
insufficient capacity
of the power supply transformer.
Check if an alarm occurs when the wiring breaker, earth leakage breaker
(with
overcurrent protection function), or electromagnetic contactor is ON.
⇒
Review the power supply transformer capacity.
VFD internal atmosphere error
⇒
Check the ambient temperature of the VFD.
CHARGE lamp failure (lamp break)
⇒
Replace the VFD.
Table 7-9 "Operation Error" Display Details and Remedies
LED display Error name
oPE02
Invalid parameter setting range
A value outside the range was set to the parameter.
Cause Measure
A value outside the range was set to the
parameter.
Check which of the parameters are set erroneously with U1-18 (OPE error
parameter).
⇒
Set the parameter correctly.
Note: If two or more operation errors occurred simultaneously, OPE mm is displayed in priority to OPE02.
