3.2.3.3 - Profile Position Mode
Profile Position Mode
In this mode, a trapezoidal trajectory generator gives the drive the possibility to execute a positioning with preset
parameters as target position, profile speed and acceleration.
In profile position mode, these bits in the control word are relative to the control of the trajectory:
Bit Number
Profile Position Mode
4
new set point
5
change set immediately
6 0:
absolute
1: relative
The movement will be triggered by a rising edge of bit 4 (new_set_point) of the control word. The
acknowledgement of the new set point is confirmed by bit 12 (setpoint acknowledgement) of the status word. The
target position will be taken as relative to the current position if bit 6 of control word = 1.
The speed profile is trapezoidal (motion profile type = 0) or S-curve (motion profile type = -1).
