Direct Mode
In the Direct mode of operation, the Speed Command output from the ML–Trim that is
connected to the motor drive can be set directly. Direct mode is an open-loop mode of
operation. Scaling, Acceleration/Deceleration, and closed loop compensation (PID)
software are not involved in the Direct mode. The Direct mode is used in conjunction
with the Run and Stop controls.
Caution: To avoid damage to your system, the ML –Trim must be calibrated and the
motor drive set up before you enter the Direct Control Parameters. Refer to
Installation/Setup: Calibration, page 2-17.
The Direct Setpoint (CP-06) is entered as a percentage of the ML–Trim's calibrated full
scale Speed Command output. To enable or disable Direct mode, use the Direct
Enable (CP-61).
The factory default Control Parameters for the Direct mode are found in Table 3-2. To
modify the default parameters, refer to Table 3-3. If you are uncertain how to enter a
Control Parameter, review the
Operations: Keypad section, page 3-3.
