Stroke Dependent Deceleration (continued):
System velocity command can be either external or internal.
VS can be set to either INT or EXT. INT is default.
INT requires the speed to be set with the VELO parameter.
VELO valid values are 0 to 10000. Default is 10000(100%). Units are 0.01%
EXT uses the 0 to 10v analog voltage at pins10/9 to command speed.
This speed signal may be ramped with the VRAMP parameter.
VRAMP valid values are 1 to 5000. Default is 50. Units are msec.
Deceleration characteristic is controlled by the CTRL parameter.
CTRL valid options are LIN, SQRT1, and SQRT2. Default is SQRT1.
SQRT1 gives the best performance for most systems. SQRT1 balances quick motion control with
accurate final position holding.
SQRT2 increases the gain at the final position, which may provide more precise load holding.
This higher gain may introduce final position instability.
LIN gives the most stable option, but requires more time to complete the motion profile.
