8
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 Speed Control
(Pn120) is 2 and the Torque Limit Selection (Pn521) is 3 or 6.
Explanation of Settings
*1. The Gain switching delay time in speed control (Pn121) becomes effective when the gain is switched
from 2 to 1.
*2. The Gain switching hysteresis in speed control (Pn123) is defined in the drawing below.
*3. When the Gain switching command of MECHATROLINK-II communications (G-SEL) is 0, the gain
switches to Gain 1. When the command is 1, the gain switches to Gain 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.
