The HS35A encoder can be wired for single phase or two-phase

operation, either with or without complements, with or without markers.

See connector options and wiring diagrams.

CAUTION

When wiring for differential applications (A,A,B,B,Z,Z), A

and A should be wired using one twisted, shielded pair;

B and B should be in a second pair, etc. Failure to use

complementary pairs (say, using A and B in a twisted

pair) will reduce noise immunity significantly.

For encoder output that correctly reflects the direction of rotation, proper

phasing of the two output channels is important. Phase A channel leads

phase B channel for clockwise shaft rotation as viewed from the back

(non-mounting side) of the encoder for standard phasing options ("A",

"C", "E", "G", "J", "M", "U", & "W"). Follow instructions under corrective

installation as needed to reverse the direction of output or purchase

HS35A with reverse (Dynapar HS35) phasing (options "B", "D", "F", "H",

"K", & "N").

CORRECTIVE ACTION FOR PHASE REVERSAL

If Encoder Direction is Reversed:

Remove power.

Exchange wires on cable, either at encoder cable end, or at

speed controller end (but not both):

a.) Single Ended 2 Phase Wiring (see wiring diagram below)

Exchange A and B at the user end of the wires.

b.) Differential 2 Phase Wiring (see wiring diagram below)

Exchange either A with A in the phase A pair OR B with B in

the phase B pair but NOT both.

Apply power.

Verify encoder feedback is correct, using hand rotation of

shaft, or jog mode of the speed controller.

Interconnecting cables specified in the wire selection chart are based on

typical applications. Refer to the "Wiring Diagrams" below for suggested

cable types. General electrical requirements are: stranded copper, 22

thru 16 gauge, each wire pair individually shielded with braid or foil with

drain wire

* Maximum cable length (and line driver selection) is limited by several

factors: line driver protection, maximum RPM, PPR, output voltage

and cable capacitance. The open collector driver (option 2) is much

more heavily limited by output frequency on long cable runs, and is

not recommended for new applications. These factors may dictate

maximum potential cable length.
