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.
● Setting
