5.3.4 Position Mode
Work process description
The position mode is realized by S-shaped acceleration and deceleration curve. User can
set the initial speed (address 200E0010h), maximum speed (address 60810020h),
acceleration time (address 60830020h), deceleration time (address 60840020h), and
total pulse number (address 607A0020h) to achieve precise position control via the bus.
The S-shaped acceleration / deceleration curve is shown in the figure below.
Position mode acceleration/deceleration curve
When the total pulse number set by user is small, the motor may need to decelerate
before it accelerates to the maximum speed (that is, the motor does not accelerate to
the maximum speed set by the user during actual operation). The speed curve is shown
in the figure below. The solid line in the figure shows the actual running curve of the
motor, and the dotted line is the curve that motor needs to run, to accelerate to the set
maximum speed. The theoretical total pulse number is the minimum total pulse
number calculated according to the user-set parameters (initial speed, maximum speed,
acceleration time, deceleration time). When the total pulse number set by the user is
less than the theoretical total pulse number, the motor will run as shown by the solid
line in the figure.
