General Information
Description Sets the user current command.

Range
Minimum range value = maximum of IL.LIMITN and -MOTOR.IPEAK
Maximum range value = minimum of IL.LIMITP and MOTOR.IPEAK

Description
This parameter sets the user current command value.
The current command value, which is provided to the current loop (IL.CMD), can be limited fur-
ther using a parameter setting or I
2
t calculation. IL.CMDU is limited also by motor peak current,
IL.LIMITN (pg 360) and IL.LIMITP (pg 361).

Description
IL.DIFOLD is the output of the drive foldback algorithm. It is an artificial current, which can be
higher or lower than the drive peak current (DRV.IPEAK). When IL.DIFOLD is lower than the
existing current limit (such as IL.LIMITP (pg 361)), it becomes the active current limit.
IL.DIFOLD decreases when the actual current is higher than drive continuous current and
increases (up to a certain level) when the actual current is lower than drive continuous current.
