Modbus Test Mode Error
Modbus communications self-diagnostics
[H1-xx =
7F]
was done while the drive was running.
Stop the drive and do Modbus communications self-diagnostics.
Note:
If the drive detects this error, the terminal assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.

STo
Safe Torque OFF
Safe Disable inputs H1-HC and H2-HC are open.
•
Make sure that the Safe Disable signal is input from an
external source to terminal H1-HC and H2-HC.
•
When the Safe Disable function is not in use, connect
terminals H1-HC and H2-HC.
There is internal damage to the two Safe Disable
channels.
Replace the board or the drive. For information about replacing
the control board, contact the manufacturer or your nearest sales
representative.
Note:
•
The drive will not output an alarm signal for this alarm.
•
If the drive detects this error, the terminal assigned to
H2-01, H2-02, H2-03 = E [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Safe Torque OFF]
will be ON.

Safe Torque OFF Hardware
One of the two terminals H1-HC or H2-HC
received the Safe Disable input signal.
The Safe Disable input signal is wired incorrectly.
•
Make sure that the Safe Disable signal is input from an
external source to terminal H1-HC and H2-HC.
•
When the Safe Disable function is not in use, connect
terminals H1-HC and H2-HC.
There is internal damage to one Safe Disable
channel.
Replace the control board 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 assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.

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 assigned to

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]
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
.
•
If the drive detects this error, the terminal assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.
•
If the drive detects this error, it will operate the motor as specified by the Stopping Method set in
L6-51 [Trq Det1 Action]
when
L6-01 = 1 [Trq Det1 Select = Enabled]
.
