Analog input/output comparison chart
Note 1: -10 to +10V frequency setting input and torque limit setting input can be made only from
O2 terminal. They cannot be input simultaneously.
Note 2: SJ300 does not have interface power supply for negative voltage.
Please prepare external power supply when inputting negative voltage at O2 terminal.
(5) J-DG (Digital input PCB)
Please use SJ-DG.
