12.2.2. Profile Acceleration
The profile acceleration defines the default rate of acceleration that
is used whenever the motor accelerates in Position mode.
The profile acceleration is recorded in the system variable
Profile_acceleration.
By default, Profile_acceleration is set equal to the Work
Acceleration Default, specified by parameters Pn2A4 and Pn2A5:
Pn2A4: The profile acceleration in user acceleration units, in the low
bits format.
Pn2A5: The profile acceleration in user acceleration units, in the
high bits format.
Pn2A4 is used to store the profile acceleration if its value is less
than 65536. Values over 65536 must be converted to high bits
format, and stored in Pn2A5, which can hold values up to 256.
The value of Profile_acceleration can be changed using the
ACCELERATION command. To set Profile_acceleration equal to a
variable, use the SET_VAR command.
12.2.3. Profile Jerk Smoothing Time
Jerk smoothing time defines the time required for the changing of
acceleration and deceleration, and is set in milliseconds.
The Jerk smoothing time is recorded in the system variable
Jerk_smoothing_time.
By default, Jerk_smoothing_time is set equal to the Work Jerk
Smoothing Time Default, specified by parameter Pn2A6.
The value of Jerk_smoothing_time can be changed using the
command JERK_TIME. To set Jerk_smoothing_time equal to a
variable, use the SET_VAR command.
