Torque (Torque)
Measures frequency f of the waveform specified as the source and calculate the torque.
A(f+c)
f: Measuring frequency A and C: Coefficients
Math Source Waveforms (Source)
The options are the same as were described for basic arithmetic. However, you can select the input channels of
logic modules (select the channel, and then select the bit).
You cannot select the input channel of a frequency module. For details, see “Notes Regarding Using the Digital
Filter and Real Time Math” in the Real Time Math (/G3)/Power Math (/G5) User’s Manual, IMDL850E-51EN.
Slope (Slope), Level (Level), Hysteresis (Hysteresis)
Set the signal level1, the slope (rising or falling), and the hysteresis2 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.
Deceleration Prediction (Deceleration Prediction)
Set whether to compute the deceleration 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 (four
settings) of the pulse one period before the pulse input stopped.
• OFF: Stop prediction is not performed.
Coefficients (A and C)
Set the scaling coefficient (A) and the frequency reference (C).
