ALPHA
For bidirectional operation of the encoder, proper phasing of the two
output channels is important. Phase A channel leads phase B channel
for clockwise shaft rotation as viewed from the anti-drive or accessory
end of the motor (M3 mounting end).
CORRECTIVE ACTION FOR PHASE REVERSAL
1) Remove Power.
2) 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)
Exchange A and B at the use end of the wires.
b) Differential 2 Phase Wiring (see wiring diagram)
Exchange either A with A in the phase A pair OR B with B
in the phase B pair but NOT both.
3) Apply Power.
4) 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 system drawing for specific cable
requirements where applicable.
Physical properties of cable such as abrasion, temperature, tensile
strength, solvents, etc., are dictated by the specific application.
General electrical requirements are: stranded copper, 22 thru 16
gauge (Industrial EPIC Connector options can use 14 AWG), each wire
pair individually shielded with braid or foil with drain wire, 0.05 uF
maximum total mutual or direct capacitance, outer sheath insulator,
1,000 ft. max. See Wire Selection Chart for some suggested cables.
NOTE
When using the industrial connector (“G”, “P”, “V”, “X”,
or “Z” options), the minimum wire size is 20 gage, and
20 gage (only) wire ends must be tinned with solder
before connection at the
screw terminals.
