Flowchart of the tuning steps in the semi-auto gain mode
Set PB-32 (response bandwidth of the speed loop in the auto and semi-audit gain adjustment mode). The
bandwidth value is 80 (by default).
Set PB-33 to 2 (semi-auto mode, non-persistent adjustment). The adjustment starts after the the revolution
speed command is entered manually.(The Jogmode or the upper controller can be used to enter the rotation
speed command). LEDwill display the calculated inertia value during the process. After the adjustment is
performed for a while, stop the calculation when the the inertia of the system becomes stable and save the
calculated load inertia ratio toPB-35. The rigidity and bandwidth settings in PB-32 are referred to during the
process of the calculation.
PB-32 is the setting of the response bandwidth for the speed loop in the auto and semi-auto gain adjustment
mode:
1~50Hz: Low rigidity, low response.
51~250Hz: Intermediate rigidity, intermediate response.
251~550Hz: High rigidity, high response.
Higher value for faster response
Check if the line distribution
and idling are normal.

function for tuning with the
