The rotation speed exceeds the display range.
Check the connection with the sensor.

Beyond the alarm HI limit
Rotation speed is at a faster or slower speed than expected.
Confirm that rated rotation speed and rotation are not locked
and so forth.

Question
Answer/remedy
Sensor
Is a correct indicated value
displayed by simply connecting
sensor(s)?
Match the sensor output and indicator by equivalent input
calibration or actual load calibration. Then, the indicated value is
displayed in proportion to the sensor output.
Wiring and
connection
The power cannot be turned on.
Check to see if the power cord is properly connected.
If not, connect the power cord properly.
Check to see if the power source is within the specified range.
If not, use a power source within the specified range.
The indicated value is
abnormal.
Check to see if the sensor is properly connected.
If not, connect the sensor properly.
Check the sensor for damage. Connect a normal sensor.
Check the sensor for a mechanical load. Prevent such a load.
Use MONITOR terminal to check if the voltage is within the
specified output range of torque meter.

Setting and
operation
It is desired to decrease the
number of digits of the
numerical value.
Since there is a need to decrease the number of digits of the value
input during equivalent input calibration or actual load calibration,
perform calibration again. Also, set the load-related setting values,
such as HI and LO limit values, again according to that number of
digits.
How to get hold is unclear.
The control method may differ according to the hold mode used.
See "7-1.Hold functions of torque" on page 55.
Judgment results are not output.
Check to see if the output cable is properly connected.
If not, connect the output cable properly.
In the case of comparison output, the output conditions differ
according to the setting of comparison timing.
See "6-4.Comparison timing" on page 53.
Lower digit(s) of the indicated
value fluctuates.
Check for calibration exceeding 10000 at approximately 3.3V.
Since the resolution is approximately 10000 with respect to
approximately 3.3V, calibration exceeding it will cause coarseness,
and the indicated value will fluctuate and not become stable. For
using as it is, ignore the lower digit(s), or set the min. scale
division again.
Is the voltage output and
D/A option different?
The monitor output is made by turning back the sensor input. It is
different from the D/A converter that converts from digital to
analog through digital processing. Consider that the D/A converter
is synchronized with the indicated value.
