Drive mode 1 is used when the input set as 2
nd
source is not entered into multi-input
(I17~I24)
Drive mode 2 can input frequency setting and drive command as a 2
nd
setting value by
using multi-input terminal. In case of driving away from inverter by communication, it is
used when quit the communication and operate by inverter.
The switching method for Drive mode 1 and Drive mode 2 is as follows
If multi-input terminal set as Drive mode 2 is off, it used as Drive mode 1. If multi-input
terminal set as Drive mode 2 is on, it used as Drive mode2.
