G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
*1
The default setting is 180 for a Drive with 200 V and 1 kW or greater, or with 400 V.
•
This object determines speed loop responsiveness.
•
The setting for the speed loop gain must be increased to increase the position loop gain and improve
the responsiveness of the entire servo system. Setting too high, however, may result in vibration.
•
The setting unit for the Speed Loop Gain 1 (3101 hex) is Hz if the Mass Ratio (3004 hex) is set
correctly.
Response when the speed loop gain is changed.
*1
The default setting is 310 for a Drive with 200 V and 1 kW or greater, or with 400 V.
•
Set the speed loop integral time constant.
•
The smaller the set value, the faster the error approaches

when stopping.
Response when the speed loop integral time constant is changed.
