Switching Between Two Motors

 How to drive two different motors with different settings?
Q
 How to store separate setting configurations for two different motors?
 How to change between setting configurations for batch production?
 Turn the "2nd-motor control [SET]" for the input terminal function on to change target
A
parameters. This function makes it possible to switch between different parameter
configurations to control two different types of motors.
 The "2nd-motor control is selected [SETM] (60)" output terminal function turns on when the
[SET] function is turned on.
 Parameters in the 200s parameter number of function groups A, b, C, and H are the second
control parameters.
(Example) The second control parameter corresponding to the "Frequency input source selection,
1st-motor [A001]" is the "Frequency input source selection, 2nd-motor [A201]".
 These parameters do not change, even when changing [SET] during inverter operation. In this
!
case, parameters change after the output is cut off.
 Please allow at least one second for changes to occur if you want to switch the [SET] terminal
and immediately run operations.

2nd-motor control [SET]:
Turn this function on to switch to the second control
parameter.
2nd-motor control is selected [SETM]:
After [SET] is turned on, switching to the second
control parameter turns this signal on.
