time are not set.
Use the keypad to set the date and time.
Note:
•
Do a Fault Reset to clear the fault.
•

UL3
Undertorque Detection 1
A fault occurred on the machine.
Example: There is a broken pulley belt.
Examine the machine and remove the cause of the fault.
The parameters are incorrect for the load.
Adjust
L6-02 [Torque Detection Level 1]
and
L6-03 [Torque
Detection Time 1]
settings.
Note:
•
The drive detects this error if the drive output current is less than the level set in
L6-02
for longer than
L6-03
.
•
Do a Fault Reset to clear the fault.
•
If the drive detects this error, it will operate the motor as specified by the Stopping Method set in
L6-01 [Torque Detection Selection 1]
.

Uv1
DC Bus Undervoltage
There is a phase loss in the drive input power.
Correct errors with the wiring for main circuit drive input power.
There is loose wiring in the drive input power
terminals.
Tighten the terminal screws to the correct tightening torque.
The drive input power voltage is changing too
much.
•
Examine the input power for problems.
•
Make the drive input power stable.
•
If the input power supply is good, examine the magnetic
contactor on the main circuit side for problems.
There was a loss of power.
Use a better power supply.
The main circuit capacitors have become
unserviceable.
Examine the capacitor maintenance time in monitor
U4-05
[CapacitorMaintenance]
. If
U4-05
is more than 90%, replace the
control board or the drive. For information about replacing the
control board, contact Yaskawa or your nearest sales
representative.
The relay or contactor on the soft-charge bypass
relay is damaged.
U4-06 [PreChargeRelayMainte]
shows the performance life of
the soft-charge bypass relay. If
U4-06
is more than 90%, replace
the board or the drive. For information about replacing the board,
contact Yaskawa or your nearest sales representative.
Note:
•
The drive detects this error if the DC bus voltage decreases below the level set in
L2-05 [Undervoltage Detection Lvl (Uv1)]
while the drive is running.
•
The
Uv1
detection level is approximately 190 V for a 200 V class drives. The detection level is approximately 380 V for 400 V class drives. The detection level is
approximately 350 V when
E1-01 [Input AC Supply Voltage]
< 400.
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for this fault.
•
L5-08 [Fault Reset Enable Select Grp2]
disables the Auto Restart function.

Uv2
Control Power Undervoltage
The value set in
L2-02 [Power Loss Ride Through
Time]
increased and the momentary power loss
recovery unit is not connected to the drive.
Connect the momentary power loss recovery unit to the drive.
There was a problem with the drive hardware.
•
Re-energize the drive.
•
If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact
Yaskawa or your nearest sales representative.
Note:
•
The drive detects this error if the control power supply voltage decreases.
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for this fault.
