Parameters Details
 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).

Set the hysteresis width above and below the judgment level set in the Gain Switching Level in Speed
Control (Pn122). The unit depends on the setting of the SWITCHING mode in Speed Control (Pn120).
The following shows the definitions for the Gain Switching Delay Time in Speed Control (Pn121), Gain
Switching Level in Speed Control (Pn122), and Gain Switching Hysteresis in Speed Control (Pn123).
