3.4.4 Changing the control logic
FR-D700 SC 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 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.
●
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.
The input signals are set to source logic (SOURCE) when shipped from the factory. To change
the control 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
connector position.)
