MP-41 LEAD FREQUENCY
The Lead Frequency (MP-41) displays the frequency of the Lead Frequency Input
(J6 pin 1) in units of hertz (pulses per second). Lead Frequency (MP-41) is not averaged or
filtered; it is the ten millisecond frequency calculation prior to the display update. Because 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 in Feedback Frequency, MP-43.
MP-42 PULSE ERROR COUNT
The Pulse Error Count indicates the difference between the Lead and Feedback pulses received
during the Follower mode of operation. It is an indication of the position error between the lead
and follower devices. This error is cleared to zero when the MLP-Trim enters the stop state.
MP-43 FEEDBACK FREQUENCY
The Feedback Frequency (MP-43) displays the frequency of the Feedback Frequency Input (J6
pin 2) in units of hertz (pulses per second). Feedback Frequency (MP-43) is not averaged or
filtered; it is the ten millisecond frequency calculation prior to the display update. Because
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:
