• The inertia ratio of
Pr.880
is used when the speed controller on the model side calculates the torque current command
value.
• The torque current command of the speed controller on the model side is added to the output of the actual speed controller,
and set as the input of the iq current control.
Pr.828
is used for the speed control on the model side (P control), and first gain
Pr.820
is used for the actual speed
controller.
NOTE
• The model adaptive speed control is enabled for the first motor.
• Even if the driven motor is switched to the second motor while
Pr.877
= "2", the second motor is operated as
Pr.877
= "0".
