MLP–TRIM CALIBRATION

1) Make sure that the MLP–Trim is still in “R–Stop”. If the MLP–Trim is not in

“R-Stop”, then put it in “R–Stop” by opening the R–Stop logic input

(J6 pins 6, 8). Refer to

Installation/Setup: Wiring, Inputs, R–Stop

2) Enter the resolution (PPRs) of the feedback sensor in the PPR Feedback

Control Parameter (CP-31) by entering the following on the keypad:

Press “Code Select”

Enter “31” (PPR Feedback)

Press “Enter”

Enter the Pulses Per Revolution (PPR) of the feedback sensor

Press “Enter”

The Tach for the Direct mode is now scaled.

3) Set the MLP–Trim's maximum speed potentiometer (located on the rear) as

far counter clockwise as it will turn. This is the minimum speed setting.

4) Enable the MLP–Trim's Direct mode by entering the following on the keypad:

Press “Code Select”

Enter “61” (Direct Enable)

Press “Enter”

Enter “1”

Press “Enter”

5) Put the MLP–Trim into “Run” by deactivating (shorting) the R–Stop input
