*2. The Gain Switch Hysteresis Setting (Pn34) is defined as shown in the following figure.
Pn33
0
*3. The amount of change is the value within 166 µs.
Example: When the condition is a 10% change in torque in 166 µs, the set value is 200.
*4. This is the encoder resolution value.
*5. The meanings of the Gain Switch Time, Gain Switch Level Setting, and Gain Switch Hysteresis
Setting are different from normal if this parameter is set to 10. (Refer to Figure F.)
