Speed Select/Speed Reference
Several sources can provide the speed reference to the drive. A
SCANport device or the L Option determine the source.
The default source for a command reference (all speed select inputs
open) is Speed Ref 1. If any of the speed select inputs are closed, the
drive uses other parameters as the speed reference source.
The following table defines the input state of the Speed Select inputs
for a desired speed reference source:
Closed = Applied = 1
Open = Removed = 0
Example 1
For the first example, input mode 2 has been selected. The application
calls for a local Human Interface Module (HIM) speed command or
remote 4 – 20mA from a PLC. To program the drive for this example:
1. Set the value of SP An In1 Select (parameter 133) to 1.
2. Set the value of SP An In1 Scale (parameter 135) to 0.125.
3. Link SP An In1 Value (parameter 134) to Speed Ref 1
(parameter 29).
4. Set mA In Offset (parameter 103) to 0.
5. Set mA In Scale (parameter 104) to 2.
6. Link mA In Value (parameter 102) to Speed Ref 2 (parameter 31).
