Parameters Details
*5. When the set value is 10, meanings of the Gain switching delay time in speed control (Pn121), the
Gain switching level in speed control (Pn122), and the Gain switching hysteresis in speed control
(Pn123) differ from the normal case. (Refer to Figure D).
Set the delay time when returning from gain 2 to gain 1 if the SWITCHING mode in Speed Control
(Pn120) is set to 3 to 5.
In SPEED CONTROL mode, this is enabled when the SWITCHING mode in Speed Control
(Pn120) is set to 3 to 5. Set the judgment level for switching between gain 1 and gain 2.
The unit depends on the SWITCHING mode in Speed Control (Pn120).
