Parameters Details
The settings for the Gain Switching Level in Speed Control (Pn122) and the Gain Switching
Hysteresis in Speed Control (Pn123) are enabled absolute values (positive/negative).
Explanation of Settings
Select the switching condition between gain 1 and gain 2 when the Gain 2 Setting (Pn114) is set
to 1.
The gain is always gain 1 regardless of the gain input if the switching input is not assigned when
Pn124=2.
*1. The Gain Switching Delay Time in Torque Control (Pn125) is enabled when returning from gain 2 to
gain 1.
*2. The Gain Switching Hysteresis in Torque Control (Pn127) is defined as shown in the following figure.
*3. The change amount is the value within 1 ms.
[Example] When the condition is a 10% change in torque in 1 ms, the set value is 200.
