AUTOMATIC GAIN ADJUSTMENT SUPPORT DEVICE

摘要

An automatic gain adjustment support device according to this invention supports automatic adjustment of a control gain in a control loop for a servomotor controller which controls a servomotor. The automatic gain adjustment support device includes a frequency characteristic measuring unit, a display unit, a condition setting unit, an automatic gain adjusting unit, and a parameter setting unit. The frequency characteristic measuring unit measures frequency characteristics of the control loop in the servomotor controller. The display unit displays, in Bode diagram form, the frequency characteristics of the control loop. The condition setting unit sets a target gain value at a predetermined frequency. The automatic gain adjusting unit automatically adjusts the control gain in the control loop to the target gain value at the predetermined frequency set by the condition setting unit. The parameter setting unit sets the control gain to the servomotor controller.
