Wiring – The Encoder Power
The OTAC-01 module does not supply power for the encoder. An
external power supply (as diagrammed below) is recommended. The
drive’s 24 VDC supply from terminals X1:10 and X1:11 can be used if
the total draw on the supply does not exceed 250 mA. Use the following
table to determine if the drive’s supply can be used.
1. Connect as follows:
Wiring – The Encoder
1. Determine the encoder wiring configuration:
• Refer to “Phasing” on page 8 to determine if the encoder has normal
pulse order – encoder channel A/1 pulse leads channel B/2 pulse.
• Refer to “Encoder Output Types” on page 9 to determine the
encoder’s output type.
• For push-pull types, refer to the manufacturer’s recommendation for
connection – either
single-ended
or
differential
can be used.
2. Refer to “Wiring Diagrams” on page 10, select the appropriate diagram,
and wire the encoder.
