Diagrams of Gain Switching Setting
Switching between Gain 1 (3100 to 3104 hex) and Gain 2 (3105 to 3109 hex) occurs at the
following timing. For the position loop gain, switching occurs based on the setting of 3119 hex.
The details of the gain switching settings vary depending on the control mode used. For the
details of settings available in each mode, refer to Gain Switching on page 7-25.
Gain Switching Mode = 2: Gain Switching (GSEL)
Instant switching occurs when a gain switching command is issued from the network.
Gain Switching Mode = 3: Switching by Command Torque Value
If the absolute value of the command torque exceeds the sum of the Gain Switching Level in
Position Control (3117 hex) plus the Gain Switching Hysteresis in Position Control (3118 hex),
the gain switches to gain 2.
If the absolute value of the command torque exceeds the difference of the Gain Switching
Level in Position Control (3117 hex) minus the Gain Switching Hysteresis in Position Control
(3118 hex) for the time specified in the Gain Switching Delay Time in Position Control (3116
hex), the gain switches back to gain 1.
