Torque signal input connector (TORQUE)
(motor version)

motors.
Revolution signal input connector (SPEED)
(motor version)
Receives signals from revolution sensors when evaluating
motors.
Functional Description
By using the motor evaluation function (motor version), the rotating speed, torque, and
output of a motor can be determined from the signal that is proportional to the rotating
speed of the motor, and the signal received from a torque meter, which is proportional to
the motor’s torque. The signal applied from the revolution sensor or torque meter to the
WT3000 can be selected from analog signal (DC voltage) or pulse signal. In addition,
the synchronous speed and slip of a motor can be determined by setting the motor’s
number of poles. Furthermore, the active power and frequency that are measured by the
WT3000 and the motor output can be used to compute the motor efficiency and the total
efficiency.
Types of Measurement Functions
Measurement functions consists of Speed (rotating speed), Torque, Pm (motor output
or mechanical power), SyncSp (synchronous speed), and Slip. For details on the
determination of the measurement functions, see section 1.10. Set equations for the
motorefficiency((Pm)/(PΣA)×100)andtotalefficiency((Pm)/(PΣB)×100)accordingto
the procedures in section 5.7 in the User’s Manual IM760301-01E.
Limitations by Measurement Modes
Measurement functions of the motor evaluation function cannot be measured in wide
bandwidth harmonic measurement, IEC harmonics measurement, voltage fluctuation and
flicker measurement, and cycle-by-cycle measurement modes.

Explanation
• Selecting the Input Range of the Revolution and Torque Signals
Two types of range settings are available: fixed and auto.
• Fixed Range
Select the input range from the following:
20 V, 10 V, 5 V, 2 V, or 1 V
• Auto Range
Select ON for the auto range setting to enable auto range. The range changes
automatically depending on the amplitude of the input signal.
• Range Increase
• When the rotating speed or torque data exceeds 110% of the current
measurement range, the measurement range is increased.
• When the peak value of the input signal exceeds approximately 150% of the
measurement range, the range is increased.
• Range Decrease
When the rotating speed or torque data is less than 30% of the measurement range
and the peak value of the input signal is less than 125% of the next lower range,
the measurement range is decreased.
Note
When non-periodic pulse waveforms are applied during auto range, the range may not remain
constant. If this happens, use the fixed range setting.

selecting items and entering values and character strings. For
details on the procedures, see section 3.14 in the User’s Manual
IM760301-01E.
The settings covered in this section apply to the case when the input signal type is set to
Analog. You do not have to specify the settings in this section if the input signal type is
set to Pulse.
1. Press SHIFT+SCALING (MOTOR SET) to display the Motor Set dialog box.

2. Press the cursor keys to select Line Filter.
3. Press SET. A line filter selection box appears.
4. Press the cursor keys to select a value between OFF and 50 kHz.
5. Press SET to confirm the line filter. The same filter is set to both the revolution
signal and the torque signal.

Explanation
• Selecting the Line Filter
A line filter can be inserted into the circuits that measure the revolution signal and
torque signal. It eliminates harmonic noise.
The cutoff frequency can be selected from the list of choices below.
OFF, 100 Hz, and 50 kHz
Selecting OFF disables the filter.
Note
If the signal type (see section 1.3) is Pulse, the filter function does not work.
• Line Filter and Measurement Mode
• The line filter setting is common to all measurement modes except cycle-by-cycle
measurement mode. The initial setting is OFF.
• The line filter setting in cycle-by-cycle measurement mode is independent of the
setting in other measurement modes. The initial setting is 50 kHz.
• Selecting the Synchronization Source
• Select which element’s input signal will be used as a synchronization source
(synchronized to the zero-crossing point of the selected signal) when measuring
the analog signal of the revolution signal and torque signal. Select the signal to
be the synchronization source from the choices below. The selectable items vary
depending on the installed elements.
U1, I1, U2, I2, U3, I3, U4, I4, Ext Clk (external clock)*, and None
* For the specifications of the Ext Clk (external clock), see the explanation in section
7.4.
• The measurement period determined by the synchronization source selected here
is used to measure the analog signal of the revolution signal and torque signal. If
you specify no synchronization source by selecting “None,” the entire sampled data
within the data update interval is the data used to determine the rotating speed and
torque. For details on the synchronization source, see appendix 6 in the User’s
Manual IM760301-01E.
•If the rotating or torque signal is a pulse signal, the average of the pulse signal
interval over the measurement period determined by the synchronization source
selected here is the measured value of the rotating or torque signal. If the pulse signal
interval is not within this measurement period, the measured value is determined
from the previous interval.
•To achieve stable measured values by matching the measurement period with
the measurement functions of voltage, current, active power, and so on such
as during the measurement of the motor efficiency, it is recommended that the
synchronization source be set to the same synchronization source specified in
section 4.7 in the User’s Manual IM760301-01E.
