Parameter Descriptions
DIRECT IP SELECT
PREF: 78.10
Default: 0
Range: See below
The direct input to the speed loop is an analog input which is sampled synchronously with the speed loop. This ensures that
the speed loop always has the most up-to-date value of the input, allowing it to respond faster. Any one of the four analog
inputs can be selected as the direct input. If NONE is selected, the input is set to zero. When not in use, it should be disabled
by selecting NONE.
