IM DL850E-01EN
Coefficient (K)
Set scaling coefficient K.
Range: −9.9999E+30 to +9.9999E+30. The default value is 1.0000.
Frequency (Frequency)
Calculates the frequency of the waveform that has been assigned to Source.
Math Source Waveform (Source)
The options are the same as were described above for basic arithmetic. However, you can select an input
channel of a logic module (select the channel, and then select the bit). You cannot select an input channel of a
frequency module.
Slope (Slope), Level (Level), Hysteresis (Hysteresis)
Set the signal level,
1
the slope (rising or falling), and the hysteresis
2
of the edges that are used to detect the
periods. If the math source is the signal of a logic module, set only the slope.
1 The signal level range is the same as the trigger level range.
2 The hysteresis level is the same as the trigger hysteresis.
Scaling (Scaling)
Select the unit that is used on the vertical scale.
• Hz: The unit is hertz.
• Rpm: The unit is revolutions per minute.
Deceleration Prediction (Deceleration Prediction)
Set whether to compute the decelaration curve from the elapsed time after the pulse input stops.
• ON: Deceleration prediction is performed.
• OFF: Deceleration prediction is not performed.
Stop Prediction (Stop Prediction)
Set the time from the point when the pulse input stops to the point when the DL850E/DL850EV determines that
the object has stopped.
• 2, 4, 8, 16: Stop prediction is performed on the basis of the specified number of times the pulse period (T) of
the pulse one period before the pulse input stopped.
• OFF:
Stop prediction is not performed.
Period (Period)
Calculates the period of the waveform that has been assigned to Source.
Math Source Waveform (Source)
The options are the same as were described above for basic arithmetic. However, you can select an input
channel of a logic module (select the channel, and then select the bit). You cannot select an input channel of a
frequency module.
Slope (Slope), Level (Level), Hysteresis (Hysteresis) Deceleration Prediction
(Deceleration Prediction), Stop Prediction (Stop Prediction)
Set the slope (rising or falling), signal level, and hysteresis of the edges that are used to detect the periods as
well as the deceleration prediction and stop prediction. These settings are shared with the
operation.
