User Manual V 1-4.XX User guide

5-10 Using the L Option
With Speed Select inputs 2 and 3 open and the selector switch set to
Remote (Speed Select 1 closed), the drive follows Speed Ref 2
(parameter 31) or 4 – 20mA. With the switch set to Local (Speed
Select 1 open), all speed select inputs are open and the drive follows
the local HIM Speed Ref 1 (parameter 29).
Example 2
For the second example, input mode 7 has been selected. The
application follows a local HIM unless a preset speed is selected. 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 Speed Ref 2 (parameter 31) to 10 rpm.
5. Set Speed Ref 3 (parameter 32) to 50 rpm.
6. Set Speed Ref 4 (parameter 33) to 100 rpm.
The following table shows how the contacts operate for the speed
select switch. Because Input Mode 7 does not offer a Speed Select 3
input, Speed Ref 4 – 7 are not available.
Speed/Torque Selection
The following table defines the input state of the speed/torque mode
select inputs for a desired speed/torque mode.
Closed = Applied = 1
Open = Removed = 0
Refer to the Torque Reference Overview section of Appendix B,
Control Block Diagrams, for additional information about speed and
torque selection.
