Drive Configuration Chapter 1
Current Limit Stop
Current Limit stop is not typically set up as the normal Stop mode. Usually the
normal stop is programmed at some ramp rate. For the current limit stop a digital
input is used for the function. However, you certainly could set the normal stop
as CurrentLimit Stop
Current limit stop ramp rate is 0.1 second and is not programmable
Example
In this example the current limit was set high enough to allow the full rating of
the drive to be used in the stop sequence.
