7. Operation with external signal
7.1 External operation
The inverter can be freely controlled externally.
Parameters must be differently set depending on the operation method. Make sure of the operation method before
setting parameters, and set parameters properly to the operation mode according to the procedure mentioned below.
[Steps in setting parameters]
