Lower Level Threshold
12%
This gives a band arrangement as follows.
As good practice, the threshold limits have been chosen so the actual resistance values that trigger a change are in the
approximate center of the bands, thereby eliminating the risk of a system erroneously switching between bands.
The 4 Speed Limits for Drive Inhibit A would need to be set as below:
Inhibit A:
Speed Limit in Band 0
100%
Speed Limit in Band 1
50%
Speed Limit in Band 2
25%
Speed Limit in Band 3
0%
ACTUATOR INHIBIT EX AMPLES
Application 1: A wheelchair is fitted with a reclining backrest that has endstop switches connected to the R-net’s Inhibit inputs 4
and 5 on the ISM. In this example the switches are installed to be normally closed and the Backrest has been programmed to
use Actuator Channel 2.
A circuit such as follows is used.
The Inhibit input must be assigned to a specific software Inhibit. As this is an Actuator Inhibit, the parameters Actuator Inhibits
Channel X - Up: Assign & Down: Assign should be used.
The inputs are therefore assigned to Actuator Inhibits Channel 2 as follows:
Up: Assign - Input 4
Down: Assign - Input 5
As these inputs are connected to the ISM the Threshold levels must be set in the parameter Inputs - ISM.
