Parameters Details
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).
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 mode in Torque Control
(Pn124) is 2 and the Torque Limit Selection (Pn521) is 3 or 6.
*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.
