GE 2300 V, Medium Voltage GP Type G Drives manual Speed Reference Generation OvrRfSel

Function description

The Speed Reference Reverse function is part of the Speed Reference Generation function. It reverses the speed reference in response to a user request.

The speed reference input to the Speed Reference Reverse originates in the Local Speed Reference if Local mode active is True, or in the Remote Speed Reference if Local mode active is False. The value of Local mode active is selected with the DDI Remote/Local button.

The user request to reverse the speed reference is reflected in Reverse mode active. It depends on the value of Local mode active. If Local mode active is True, then Reverse mode active is set equal to Local rev request, which changes between True and False as the DDI reverse button is pressed. If Local mode active is False, then Reverse mode active is set equal to the signal selected by Reverse select.

When Reverse mode active is True, then the speed reference input is multiplied by –1 to obtain the speed reference output (Speed reference).
