Functional Overview

Functional Description

The SpeedSelect function block allows you to control the speed inside the application that is communicated to the Altivar drives using an analog input channel or selector switch. You have the flexibility to select 8 pre-selectable speeds using the selector switch.

Why Use the SpeedSelect Function Block?

The SpeedSelect function block is an adapted multiplexing algorithm compiled into a single function block. It was designed to facilitate user-logic development associated with the pre-selectable speed functions found on Altivar variable speed drives. Implementing the SpeedSelect function block may also ease comprehension of the user-logic while monitoring and troubleshooting the application.

Design & Realization Constraints and Assumptions

When the motor moves in forward direction, the hoist moves up and when the motor moves in reverse direction, the hoist moves down.
