D-101 Parameter ReferenceAC30V series Variable Speed DriveSpd Direct InputParameters::Motor Control::Spd Direct InputOnly apply to SVC control mode, IM or PMAC.PNO Parameter Descriptions0528 Direct Input SelectThe direct input to the speed loop is an analog input which is sampled synchronously with the speed loop. This ensures that thespeed loop always has the most up-to-date value of the input, allowing it to respond faster. Either of the two analog inputs can beselected 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.Enumerated Value : Direct IP Select0 : NONE1 : ANIN12 : ANIN20529 Direct Input RatioThe Direct Input is multiplied by this parameter.0530 Direct Input Pos LimThis limits the upper value of the Direct Input.0531 Direct Input Neg LimThis limits the lower value of the Direct Input.Functional DescriptionThe Drive is commanded to run the motor at a certain speed, which is derived from various sources, such as comms, analog inputs, commandsfrom the keypad, etc. Most of these are derived from sources which respond relatively slowly, eg every 1ms. For processes which require afaster response, the direct input is provided. This is an analog input which is sampled synchronously with the speed loop, as described above. Itis added on to the other sources of speed command to give a total speed command.
