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.
