The decryption of ID167 (P1.064) is shown in the segment display image that
corresponds to the table:
Settings for ID168 (P1.065):
The analog position command smoothing constant is only valid for analog
position commands. This value is the amount of smoothing that is used
essentially for speed control when the motor is moving towards the analog
setpoint. The smaller value (0) is a very aggressive speed that is used to move to
the analog setpoint. The largest value (1000) is a very slow speed that is used to
move to the analog setpoint.

Bit X: Bit Y: Bit U/Z:
0 = The analog position
function is not used
(disabled).
0 = When the drive transitions to ON, the current motor position is
considered 0V; the motor now moves to the corresponding motor position
based on the voltage level at V_REF/GND. The amount of movement is
defined by the volts/rev setting shown below and the speed of the
movement uses the Smoothing Constant described below.
Reserved
1 = The analog position
function is used (enabled).
1 = When the drive transitions to ON, the current motor position is
considered 0V; the motor now moves to the corresponding motor position
based on the voltage level at V_REF/GND. The amount of movement is
defined by the volts/rev setting shown below and the speed of the
movement uses the Smoothing Constant described below.
IMPORTANT
Choose the smoothing constant carefully because aggressive speed
settings can potentially damage your equipment. By using a smoothing
constant of 0 or 1, you are creating, essentially, a step input to
maximum speed as defined by the Volts/(Max. Rotation Number). A
typical value for the smoothing constant is 200…400.
