Optimization of the controller
It is recommended to carry out several positioning cycles with practical speed settings to check
the dynamic stability of the system with the actual parameter settings.
In doing so, please observe the positioning error (differential counter) on the PC operating
software or on the display of the device:
If during forward acceleration the position error reaches high positive values and the bar
graph moves to the extreme right position, this indicates that the drive cannot follow the
acceleration ramp and you should increase the parameter F02.003 “Acceleration Ramp”.
If during forward deceleration the position error reaches high negative values and the bar
graph moves to the extreme left position, this indicates that the drive cannot follow the
deceleration ramp and you should increase the parameter F02.004 “Deceleration Ramp”.
Where you find your position error remains small enough all the time, you are free to decrease
the acceleration and deceleration ramp time settings. This will cause steeper ramps and
therefore decrease the total positioning cycle time.
This concludes the procedure of commissioning of your positioning system. We recommend
saving all parameter settings on hard disc or disc and adding it to the machine documentation. In
case of repeat applications (machine with similar specifications), or after exchange of the
controller, you just need to download the settings to be immediately ready to go
