Chapter 6 Setting up parameters
HA-680_V04 - 76 -
02: Speed loop integral gain (position / speed)
Function
This parameter specifies the speed loop integral gain.
High setting If the setting is too high, the servo system will be unstable, and hunting and overshoot
will easily occur.
Low setting If the setting is too low, the responsiveness and tracking performance will be poor.
Setting
unit Lower limit Upper limit Default
- 10 9999 note
Note: The actual setting varies with the AC servo actuator model. When changing the value, consider
the defaults shown in Section 6-3, “Default parameters” as the standard (guide setting).
03: Speed loop derivative gain (position / speed)
Function
This parameter specifies the speed loop derivative gain.
Usually set this factor to 0.
High setting If the setting is too high, the servo system will be unstable, and hunting and overshoot
will easily occur.
