1-2. Features
TM500 is a torque monitor that enables waveform display of changes in torque with respect to
displacement (mainly angles), combined with UTMⅡseries with optional rotary encoder. Changes
in torque that are hard to grasp numerically can be grasped visually on waveform display.
With the color liquid crystal touch panel display adopted, twists have been provided in many places
by thoroughly paying attention to ease of understanding so that all operations can be performed
without the instruction manual. Also, having a high-speed processing capability of 4,000 times/sec
ready for fine changes in values, and being equipped with the waveform display, HI/LO limit
comparison and other various hold and judgment functions, it can be used for a wide range of
applications, such as in production control systems, automatic equipment, and testing machines.

●Drawing of torque-angle waveforms
Waveforms of torque with respect to angles at low rotation, linear motion application can be
drawn.
●Repetitive drawing of waveforms
For applications with large fluctuation or low repeatability, inspection can be repeated several
times for judgment.
●Measurement waveform control as divided by using the hold function
A measurement waveform can be divided into up to five sections, and the waveform can be
judged on each section by specifying each HI limit, LO limit, and method of judgment.
Each section can be specified by Setting (time or displacement) or external input signal “Hold.”
The method of judgment can be changed by selection under “Use Hold.”
Judgment point(s) can be kept depending on the selection under “Use Hold.”

●Control of the position at the measurement completion
The position of the measurement completion can be judged by using the End Displacement for
the Use Hold.
The End Displacement is different from other hold types, so it judges not based on a wave
starting point but based on an original point of the displacement.
●Entire waveform control by using the waveform comparison function
Comparisons can be made to judge whether or not a measurement waveform is between HI limit
and LO limit waveforms.
●Measurement-waveform-following control by using the relative comparison function
Waveforms fluctuating up and down with each measurement can be relatively compared.
By this function, comparison waveforms are relatively moved according to the load at the
Reference Point of Relative Comparison, which should previously be set by time or
displacement, on a measurement waveform.
* Relative movement can only be made in the Y-axis direction.
●Change of the control reference to the point at which loading is started or the point at
which it is finished
In the case where the X-axis of the waveform represents displacement, the reference for the hold
function and waveform comparison function can be selected from either the measurement start
point or measurement stop point.

For the measurement start point and measurement stop point, set “Front” and “Back,”
respectively, as “Waveform Reference.”
Normally, “Front” is used; however, use “Back” if displacement of the measurement stop point
is set as reference.
* In case of “Front”, the waveform of which 0°is the measurement start point is displayed.
In case of “Back”, the waveform of which 0°is the measurement stop point is displayed.
●Various measurement start and stop conditions
Measurement start and stop conditions can be selected according to application.
