46
Droop Percent
Use Droop Percent to specify the percent of base speed that the
speed reference is reduced when at full load torque. You can use
this feature to cause motor speed to droop with an increase in
load.

S-Curve Percent
Use S-Curve Percent to create an adjustable S curve ramp.
S-Curve Percent controls the level of filtering that is applied to the
output of the acceleration and deceleration ramp.
1 S-Curve Percent was added in Version 2.xx.

Not used.
50%
Applied for half of the ramp time.
100%
Applied for the entire ramp.

PTrim Output
PTrim Output represents the scaled and limited output of the
process trim function. You can use PTrim Output as a parameter
source or to offset the speed or torque reference. To offset the
speed or torque reference, you need to select either bit 0 or bit 1
in PTrim Select (parameter 51).
