Processing details
The value of the parameter (s2) is read from an inverter connected to the channel to be used (n) whose station number is (s1),
and output to (d1). For details, refer to Serial communication manual. (For the parameter numbers, refer to the each
inverter manual.)
Precautions
Three devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
