Connecting-up
The optional board has two terminal strips for the signal cables.
Connect the signal cables at the corresponding connection; terminal X401/75
is provided for the shield.
NOTE
♦
The signal inputs of tracks A, B and zero of connector X401 are provided
internally with bus terminating resistors. These are powered up in the
factory setting (switches S1-1 to S1-3 closed).
♦
The switches of the bus terminating resistors are located on the optional
board behind connector X400. Of the four switches, the upper three in the
correct installation position are responsible for the bus terminating resistors
(in the sequence A, B, zero, counting from the top).
♦
The bus terminating resistors should normally be powered up. If several
boards are controlled with pulses from one source, all the bus terminating
resistors have to be powered down except for the last one in the row.
♦
The power supply for the encoders can be switched OFF with switch S1-4.
The encoders must then be connected to an external supply. As set at the
factory, the encoder supply is active (S1-4 open).
♦
The power supply to the encoders (5 V or 15 V) is adjusted by means of
parameter P150 (see Compendium, Function diagrams, Pulse encoder
evaluation).
