Parameter adjustment support device having function for supporting parameter adjustment

A parameter adjustment support device for supporting adjustment of an acceleration/deceleration parameter, used with a numerical controller which generates a movement command for a drive axis by using a commanded acceleration/deceleration characteristic curve previously given by the acceleration/deceleration parameter, the parameter adjustment support device comprising:

• an actual acceleration/deceleration characteristic obtaining part which obtains an actual acceleration/deceleration characteristic curve relating to a velocity and an acceleration of the drive axis, from the numerical controller or an external storing device;
• a parameter setting part which sets or changes the acceleration/deceleration parameter based on an external input;
• an acceleration/deceleration characteristic displaying part which generates the commanded acceleration/deceleration characteristic curve relating to the velocity and the acceleration of the drive axis based on the acceleration/deceleration parameter which is set or updated by the parameter setting part, and contrastively displays the actual acceleration/deceleration characteristic curve and the commanded acceleration/deceleration characteristic curve;
• and
• a setting information outputting part which outputs the acceleration/deceleration parameter which is set or updated by the parameter setting part, to the numerical controller.
