Parameters Details
 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 SWITCHING mode in Position Control
(Pn115) is 2 and the Torque Limit Selection (Pn521) is 3 or 6.
Explanation of Settings
*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. When the Gain switching command of MECHATROLINK-II communications is 0, the gain switches to
1. When the command is 1, the gain switches to 2.
*4. 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.
*5. The unit (pulse) of hysteresis is the resolution of the encoder in position control. It is the resolution of
the external encoder in full closing control.
