Elmo SimplIQ Series - PT - Position Time Command

PT - Position Time Command
Purpose:
Specifies that the next BG will start a PT (Position - Time) tabulated motion and defines
the starting index in the QP[N] array.
In a PT motion, a new position reference value is picked from the QP[N] array once per
MP[4] position controller sampling times. The motion is interpolated between the points
specified by the QP[N] array. The MP[N] parameters specify which indices of the QP[N]
array are used for the motion. After BG, the PT motion starts from position QP[PT].
A PT motion terminates when, in non-cyclical mode (MP[3]=0), the index of MP[2] is
reached, or if the PT buffer underflows (CANopen only). When a PT motion terminates,
the motor is brought to a complete stop using the SD deceleration.
When a PT motion is executing, PT reads the presently executing index of the QP[N]
array.
