CONTREX ML-TRIM - Manual (Page 34)

2 - 20
Continue to gradually increase these increments by ten until you reach “90”.
Since there are no acceleration/deceleration ramps in Direct mode, a
sudden increase to “90” could cause damage in some systems.
7) Turn the ML–Trim's Maximum Speed Potentiometer clockwise until the drive
motor's RPMs are at the maximum operating speed at which you want the
system to operate. The maximum operating speed is the same speed that
you will enter in Max RPM Feedback (CP-34) to scale for the Master mode
of operation (Refer to
Operation: Control Parameters. Master Mode,
page 3-9). Check the speed (RPMs) by pressing the “Tach” key. If the
lowest setting on the ML–Trim's Maximum Speed Potentiometer still
exceeds the maximum speed at which you want the system to operate, then
adjust the Maximum Speed (Span) Potentiometer on the motor drive until
the desired speed is reached.
8) Put the Direct Setpoint back to 0% by entering the following on the keypad:
Press “Code Select”
Enter “6” (Direct Setpoint)
Press “Enter”
Enter “0”
Press “Enter”
9) Disable the ML–Trim's Direct mode by entering the following on the keypad:
Press “Code Select”
Enter “61” (Direct Enable)
Press “Enter”
Enter “0”
Press “Enter”
10) Put the ML–Trim in “R–Stop” by opening the R–Stop input (J5 pins 9, 11).
