Parameter Details
Explanation of Settings
(√: Enabled, −: Disabled)
Select the conditions for switching between gain 1 and gain 2 when the Gain Switching Input
Operating Mode Selection (Pn114) is set to 1.
The gain is always gain 1 regardless of the gain input if the Gain Switch input is not assigned to
any input if this setting is 2.
*1. The Gain Switching Delay Time in Position Control (Pn116) becomes effective when the gain is
switched from 2 to 1.
*2. The Gain Switching Hysteresis in Position Control (Pn118) is defined in the drawing below.
*3. The variation means the change amount in a millisecond (ms).
E.g. The set value is 200 when the condition is a 10% change in torque in 1 millisecond.
*4. This is the encoder resolution.
