Setting details
• Used to set the integral time constant of the speed
loop.
• Higher setting increases the response level but is
liable to generate vibration and/or noise.
• When auto tuning mode 1 2 and interpolation
mode is selected, the result of auto tuning is
automatically used. When " Pr.108 Auto tuning
mode" is set to "3: Manual mode", this parameter
can be set manually.
• Used to set the differential compensation.
• When "PI-PID control selection" setting is "PID
control is always valid", the setting of this parameter
is valid.
• Used to set the notch frequency of the machine
resonance suppression filter 1.
• Setting " Pr.119 Adaptive tuning mode" to "1: Filter
tuning mode" automatically changes this parameter.
• When " Pr.119 Adaptive tuning mode" setting is "0:
Filter OFF", the setting of this parameter is ignored.
• Used to selection the machine resonance
suppression filter 1.
• Setting " Pr.119 Adaptive tuning mode" to "1: Filter
tuning mode" automatically changes this parameter.
• When " Pr.119 Adaptive tuning mode" setting is "0:
Filter OFF", the setting of this parameter is invalid.
• Set the notch frequency of the machine resonance
suppression filter 2.
• When " Pr.134 Notch form selection 2" setting is "0:
Invalid", the setting of this parameter is invlid.
