IM WT5000-01EN
Line Filter (Line Filter(Butterworth))
You can remove high-frequency noise by inserting a line filter into the circuit used to measure the input signals.
You can select the cutoff frequency from the following options. The filter type is Butterworth.
OFF, 100 Hz, 500 Hz, 1 kHz
Selecting OFF disables the filter.
The line filter setting applies to input signals whose type has been set to analog. For input signals whose type
has been set to pulse, there is no need to configure this setting.
Pulse Noise Filter (Pulse Noise Filter)
You can remove high-frequency noise by inserting a pulse noise filter into the circuit used to measure the input
signals.
You can select the cutoff frequency from the following options. The filter type is Butterworth.
OFF, 10kHz, 100kHz, 1MHz
Selecting OFF disables the filter.
The pulse noise filter setting applies to input signals whose type has been set to pulse. For input signals
whose type has been set to analog, there is no need to configure this setting.
Sync Source (Sync Source)
When Measurement Method Is Set to Sync Source Period Average
When the MTR configuration is set to single motor (revolution signal: pulse), single motor (revolution signal:
analog), or double motor, set the sync source.
• When you are measuring analog revolution and torque signals, you can select the element's input signal
to use as the sync source from the following options. The available options vary depending on the installed
elements.
U1, I1, U2, I2, U3, I3, U4, I4, U5, I5, U6, I6, U7, I7, Ext Clk (external clock)*, Z Phase 1 (Ch D), Z Phase 3 (Ch
H), None
*
For the EXT CLK connector specifications, see section 4.3 in the Getting Started Guide, IM WT5000-03EN.
• The measurement period is determined according to the cross point of the selected sync source. This
instrument uses the measurement period to measure the analog revolution and torque signals.
• If sync source is set to None
All the sampled data within the data update interval is used to determine the rotating speed and torque.
•
When the revolution or torque signal is a pulse signal, its value is the pulse signal period averaged over the
measurement period. The measurement period is determined according to the sync source. If the pulse signal
period does not fit within the measurement period, the previous period is used to determine the measured value.
• To achieve stable motor efficiency measurements, we recommend that you set the sync source for motor
efficiency measurement to the same sync source that is set in the basic measurement conditions. This
ensures that the measurement period is in sync with the measurement functions, such as those for voltage,
current, and active power.
When Measurement Method Is Set to Digital Filter Average
The sync source setting is invalid.
