The Fast and Slow modes are designed to meet two different purposes:
Slow mode
It’s programmable so that the vehicle indoor moves slowly with accurate
operation.
Fast mode
It allows a faster velocity for outdoor long distance path.
It’s scheduled both the configuration of the maximum motor velocity and the
maximum velocity at Slow mode (See Section 3.4.2).
The wiring diagram for standalone mode is shown in Figure 2.4 for any UNIDRIVE
