Using Intelligent Input Terminals Section 4-5
The power to the inverter control part can be supplied externally as shown
below. Except driving motor, it is possible read and write the parameters by
keypad and via communication even the drive itself is not powered.
By having ability inverter doesn't block the current flowing into itself when it is
not powered. This may cause the closed circuit when two or more inverters
are connected to common I/O wiring as shown below to result in unexpected
turning the on the input. To avoid this closed circuit, please put the diode
(rated: 50 V/0.1 A) in the path as described below.
