3.4.4 Changing the control logic
FR-E700SC frequency inverters offer the possibility of choosing between two types of control logic.
Depending on the direction of the flowing current, one distinguishes between:
●
In source logic, a signal switches on when a current flows into the corresponding signal input
terminal. Terminal PC is common to the contact input signals. Terminal SE is common to the open
collector output signals.
●
In sink logic, a signal switches on when a current flows from the corresponding signal input
terminal. Terminal SD is common to the contact input signals. Terminal SE is common to the open
collector output signals.
The input signals are set to source logic (SOURCE) when shipped from the factory. To change the con-
trol logic, the jumper connector above the control circuit terminal block must be moved to the other
position.
(The output signals may be used in either the sink or source logic independently of the jumper con-
nector position.)
