TiM
Keypad Time Not Set
There is a battery in the keypad, but the date and
time are not set.
Set the date and time with the keypad.
Note:
•
Parameter
o4-24 [bAT Detection Selection]
enables and disables
TiM

TrPC
IGBT Maintenance Time (90%)
The IGBT is at 90% of its expected performance
life.
Replace the IGBT or the drive. For information about replacing
the control board, contact the manufacturer or your nearest sales
representative.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Selection = Alarm]
will activate.

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 [Trq Det1 Level]
and
L6-03 [Trq Det1 Time]
.
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
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
•
Set the conditions that trigger the minor fault using
L6-01 [Trq Det1 Select]
.

Undertorque Detection 2
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
L6-05 [Trq Det2 Level]
and
L6-06 [Trq Det2 Time]
.
Note:
•
The drive detects this error if the drive output current is less than the level set in
L6-05
for longer than
L6-06
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
•

UL5
Mechanical Weakening Detection 2
The drive detected undertorque as specified by the
conditions for mechanical weakening detection set
in
L6-08 [MechF Enable]
.
Examine the machine for deterioration.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
•
If the drive detects this error, it will operate the motor as specified by the Stopping Method set in
L6-08
.

Possible Solutions
Uv
DC Bus Undervoltage
The drive input power voltage is changing too
much.
•
Use a better power supply voltage to align with the drive rated
voltage.
•
Make the drive input power stable.
•
If there is not a fault with the input power supply, examine the
magnetic contactor on the main circuit side for faults.
A phase loss occurred 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.
Examine for loose screws and tighten them as specified by the
tightening torque values in the manual.
There was a loss of power.
Use a better power supply.
The main circuit capacitors have deteriorated.
Examine the capacitor maintenance time in monitor
U4-05
[Capacitor Maintenance]
. If
U4-05
is more than 90%, replace the
control board or the drive. For information about replacing the
control board, contact the manufacturer or your nearest sales
representative.
The drive input power transformer is too small and
voltage drops when the power is switched on.
•
Check for an alarm when a molded-case circuit breaker,
Leakage Breaker (ELCB, GFCI, or RCM/RCD) (with
overcurrent protective function), or magnetic contactor is ON.
•
Check the capacity of the drive power supply transformer.
Air inside the drive is too hot.
Measure the ambient temperature of the drive.
The Charge LED is broken.
Replace the board or the drive. For information about replacing
the control board, contact the manufacturer or your nearest sales
representative.
Note:
•
The drive detects this error if one of these conditions is correct when the Run command has not been input (while the drive is stopped).
–
The DC bus voltage <
L2-05 [UV Detection Lvl (Uv1)]
.
–
The Contactor that prevents inrush current in the drive was opened.
–
There is low voltage in the control drive input power.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
