Inverse Follower Mode

The Inverse Follower Mode is a variation of the Follower Mode. The Inverse Follower

Mode has an inverted setpoint. If you increase the value of the setpoint (CP-03 or

CP-04), then the ratio of Follower speed to Lead speed will decrease.

With the Inverse Scaling (CP-62) set to “2”, enter values in the Follower Setpoints

(CP-03 and CP-04) that represent the E.U. at which you want the system to operate.

The higher the setpoint value; the lower the Follower to Lead ratio speed.

The MLP–Trim comes factory pre-loaded with the default Control Parameters for the

standard Follower Mode. These default settings are not suitable for Inverse

applications and require modification. The factory default Control Parameters for the

standard Follower Mode are found in Table 3-34. To modify these default parameters,

refer to Table 3-35.
