Input Monitoring
These MPs monitor the MLP–Drive's inputs.
MP-41 LEAD FREQUENCY
The Lead Frequency (MP-41) displays the frequency of the Lead Frequency Input
(J5 pin 1) in units of hertz (pulses per second). The Lead Frequency (MP-41) is not
averaged or filtered; it is the ten millisecond frequency calculation prior to the display
update. Because the Lead Frequency (MP-41) is not averaged or filtered and because
of sensor irregularities, it may appear less stable than Tach (MP-40).
Numbers that are larger than 9999 are displayed with two decimal places. For
example, 10,000 hertz is displayed like the figure below in MP-43.
MP-43 FEEDBACK FREQUENCY
The Feedback Frequency (MP-43) displays the frequency of the Feedback Frequency
input (J5 pin 2) in units of hertz (pulses per second). The Feedback Frequency
(MP-43) is not averaged or filtered; it is the ten millisecond frequency calculation prior
to the display update. Because the Feedback Frequency (MP-43) is not averaged or
filtered and because of sensor irregularities, it may appear less stable than Tach
(MP-40).
Numbers that are larger than 9999 are displayed with two decimal places. For
example, 10,000 hertz is displayed as follows:
