(Note 1)
In the case of the box type with the control panel, the main
control PCB is connected with the control panel by a connector
(Connector No.:
eN
10), In this case, voltage and resistance
input signals from outside should not be used at the same time.
The following 5 types of frequency command input signals can be used for this inverter:
(1)
0 - 5 (6)V DC
(2)
0 - 10 (1 2)V DC
(3)
4 - 20mADC
(4)
0 - 20mADC
(5)
Resistance 0 - 135

For each frequency command signal, the following jumper positions are required:
