Speed Demand Ramp
Figure 8-34 PLC Based Active Damping
The menu system will allow the selection of this process. Since this function only utilizes the
speed demand and torque demand variables, then all that is required is a simple enable/disable
switch entry in the menu.
As with other induction motors, active damping should work with or without the HST starting
mode. This would be similar to completion of the HST mode startup in which the speed demand
enters into the ramp input, and the Torque command exits into the limit logic for the torque
current limit. The speed demand will have to be high enough (with slip) to keep the speed
regulator in saturation (output clamped against the current limit).
Note
Function not supported for general purpose drives
This function applies ONLY to customer specific applications and PLC HST. Please contact
Siemens for additional information.
