Wiring – Encoder
1. Remove the connector cover.
2. Determine the encoder wiring configuration:
• Refer to Phasing
order – encoder channel A pulse leads channel B pulse.
• Refer to Encoder output types
type.
• For push-pull types, refer to the manufacturer's recommendation for the
connection. You can use single-ended or differential output.
3. Refer to Wiring diagrams – Push-pull type encoder
Open collector (sinking) encoder output
(sourcing) encoder output
and wire the encoder.
Notes:
• Normally, ground the cable shield only at the drive end.
• Do not route the encoder cables in parallel to power (for example, motor)
cables.
4. Verify correct encoder phasing. Refer to
on page 159 to determine if the encoder has a normal pulse
