Installation/Wiring 2–29
Example 1
3 Wire Control - Application calls for a local Human Interface
Module (HIM) speed command or remote 4-20mA from a PLC. The
drive is programmed as follows:
• [Freq Select 1] = Adapter 1
• [Freq Select 2] = Analog Input 0
With Speed Select inputs 2 & 3 open and the selector switch set to
“Remote” (Speed Select 1 closed), the drive will follow [Freq Select
2] (Analog Input 0). With the switch set to “Local” (Speed Select 1
open) all speed select inputs are open and the drive will follow the
local HIM (Adapter 1) as selected with [Freq Select 1].
Example 2
Application is to follow a local HIM unless a preset speed is selected.
The drive is programmed as follows:
• [Freq Select 1] = Adapter 1
• [Freq Select 2] = Preset Freq 1
• [Preset Freq 1] = 10 Hz.
• [Preset Freq 2] = 20 Hz.
• [Preset Freq 3] = 30 Hz.
Contact operation for the speed select switch is described in the table
below. If the user does not select an input as Speed Select 3, [Preset
Freq 4-7] would not be available.
