Example 7: In this example, the input is programmed to run a motor in both forward and reverse
directions. The motor will idle when the potentiometer position is at the mid-point of the
scale. Using the settings in this example to disable the external FWD and REV controls.

Example 8: This example shows the use of negative slope. Negative slopes are used for controlling
pressure, temperature or flow. The input-connected sensor generates a large signal (10V)
at high pressure or flow. At negative slope settings, the AC motor drive will slowly stop
the motor. With these settings, the AC motor drive will run in one direction (reverse)
only. This can only be changed by exchanging the two wires of the motor.
Note: 1. At the external mode, combined mode 2 or combined mode 4, the inverter target frequency is set by the
input signal across terminal 2-5/4-5 if RH, RM, RL and REX are all off. If AU is on, the input signal
across terminal 4-5 will have a higher priority.
2. RL, RM, RH, REX, AU and RUN are the function names of the multi-function control terminals. For the
corresponding functions for selection and features, please refer to P.80~P.84, P.86. For wiring, please refer
to Section 3.5.6.
